Take the load off your mind with Bilanciai load cell

Categories:

If weighbridge were an organization, loads cells would be the most important employees. They are the ones who are stressed the most and the expectations from them are the highest.

Practically, any weighment would be incomplete without a load cell. So a good load cell is a primary requirement.

Just like a good employee, a good load cell makes a huge difference in the performance and accuracy of the weighbridge.

Let’s take an example –

When a load of 300 kg is weighed and the error encountered is about 15 kgs. Our assumption here generally is that this inaccuracy is constant. Surprisingly, we may find that when we weigh 300 kg the error is also intensified for about 15 times. One tries to calibrate the weighbridge to nullify 15kg slip-up. This is surely not an error to be neglected.

This is surely not an error to be neglected.

Clearly, your business is at stake when the weighment is not procured accurately.

At this point, a good load cell comes to the rescue. With multiple features benefiting your weighment, they provide a direction to follow.

Do all load cells work as efficiently and worth the price paid for it?? What makes one load cell better than the other??

Bilanciai is one such company which has a set benchmark for the quality standards of weighing solution products.

Bilanciai load cell comes with 8 strain gauges provides better reproductivity and repeatability. The protection from lightning is one of the essential elements that make it a class apart. However other features that make Bilanciai load cells more effective then others are:

  • Self-stabilized – Prevents the cell from self-rotating and twisting.
  • IP-68/IP-69K Protected – Dust Protected, Protected against submersion of water and high pressure water sprays down upto 2 Hrs.
  • Traceable – Traceability of each cell by serial number and barcode.
  • Protection from Radio Frequency – Filter circuit is provided inside the Load-cell.to protect from Radio Frequency.
  • Heavy-duty protection  – Effectively removes debris.
  • Lightning Protected – Provide a Special Insulation between the Bridge and Lower Surface, lightening protection circuit also provided inside the Load-cell.
  • Inclination up to 5 Degrees – 8 Strain Gauges gives the facility to work accurately up to the inclination of 5 Degrees of a Loadcell (15mm from vertical Position).

“Every good business knows the plight of a weighbridge showing incorrect measurements. ”

Load cell systems are crucial for accurate weight readings. Without precise and highly durable load cells, you cannot weigh with confidence.

 

Durable, well-designed load cells, sensors and weigh modules from Bilanciai can withstand heavy-duty loads while remaining highly accurate and reliable.  

Hence, choosing a good load cell with proper calibration can assist in achieving weighing accuracy.

So take the load off and comply with Bilanciai load cell for all your weighing solutions.

Achieving manipulation free weighbridge - Emula - Intelligent junction box for weighbridge - Tulsiweigh

You cannot undermine the importance of an efficient weighing solution for your manufacturing and procurement demands. Weighbridges are the cornerstone of such solutions. The biggest challenge is  – No matter how efficiently you maintain, there is always challenge to have a manipulation free weighbridge.

There is a constant demand for manager/owners who try to have a manipulation-proof weighbridge.

Technologies have been a constantally to us in providing a solution to curb such mishaps. But sadly not always we can take the benefits. The primary reason being, the cost of change of current technology is an expensive affair.

For example – An analog signal in analog weighbridge is prone to manipulations. The solution is to convert the weighbridge to a digital one. A weighbridge can be converted to digital by replacing the analog load cells with digital ones. This would demand a huge investment from an organization.

Though digitization is also the answer to the ever-increasing demand for secure and efficient weighing operations the cost of implementation of the same is the biggest impediment.

Can there be a technology that can add efficiency to weighbridges and be cost-effective in totality?

Emula is such a product from the house of Bilanciai that can convert analog signals in weighbridge to digital and hence curb out manipulation.

When it comes to weighbridge solutions, Emula gives you the required breakthrough. An intelligent junction box that can convert your analog weighbridge to digital weighbridge is like the need of the hour. A data reliable instrument that can easily transmit data over long distances and identify each cell by an individual calibration and coefficient.

Let us look at the reasons behind calling Emula the perfect weighbridge solution.

  • The Calibration King – It allows rapid calibration during installation.
  • Solitary Diagnostics – Each individual cell is monitored allowing faults to be signaled immediately using the weighing terminal.
  • Remote Control –  The operation can be verified remotely allowing system calibration to be performed without on-site intervention.
  • A fraction of a cost – EMULA can be connected to a Di0de series terminal to obtain all the benefits of digital technology without having to change existing weighing cells.Thus giving you maximum benefit at minimal cost. This saves you the cost of new digital load-cells.

Emula is not here to replace load cell.

Load cells play a very important role in determining the performance of your weighbridge. Your choice of load cell guarantees optimum performance of your weighbridge.

 

Is your weighing accuracy being hampered due to the choice of load cell ?? Our next blog will tell you which load cell to choose and why.

What are customers looking for from weighbridge service providers

Categories: Tags:
weighbridge service providers

Tulsi Weigh have been into weighing industry since last five decades. We have not only seen the evolution of it but at many places even administered them. With both experience and data of various industries we have found that service has to complement the product. Here we would like to share what should be your thought process to choose the right services for your weighbridge.

There is no way one can ignore the significance of measuring the weight of goods for a business to run properly. Weighing determines –

  1. The correct quantity
  2. Security of goods
  3. Logistic time
  4. Production forecasting

These are just few of the most important thing that is determined by a simple act of weighing.

Think of it this way – If the process of weighing is missing we fail to forecast manufacturing, delivery time, and measure of the quantity itself.

This makes the process of weighing not only necessary but critical as well.

We have emphasised on the point on how to maintain your weighing bridge. Not only as a supervisor but also as an owner. We have been talking about creating maintenance processes that will help you in a long run.

What we would take up today is beyond the periphery of the owners of weighbridge. You would be needing services pertaining to weighbridge. This is because of the unforeseen and non-controllable factors.

  1. The monsoon is a challenge for the weighbridge. The pit often collects water and affects the load cell.
  2. Operational wear and tear and calibration faults
  3. Lightening
  4. Power surge or error in power supply

These are few of the reasons when your weighbridges need professional engineers to look at the issues and resolve them.

As we discussed how critical weighing is for businesses and this leads us to be very thoughtful in choosing service providers for weighbridge services.

With our experience we have seen that customers are benefited the best when the weighbridge service providers can –

  1. Provide services within 24 hours
  2. Provide spares whenever required without delay

Both of the above points though looks obvious as a services provider is still very challenging. We will take up in our next article as how can you partner with your service provider so that you can get a better service in return.

Why do we consider the above points as challenges to weighbridge service providers?

  1. Having a network of engineers spread across multiple region is challenging. It tremendously increasing the operational efforts and cost.
  2. Having spares stocked locks the budget of service providers. Assume that they have stored spares and have not been utilized for months is a dormant asset. They could have rotated the money for operations.

Though there is a constant tussle in bringing up efficiency, the winner is always the one who could forecast and plan. We would take up an article on how we do that internally that has helped us to achieve the above two. This takes time and experience but once you achieve it becomes a rewarding asset.

 

 

Weighbridge Software- What you need for weighing

Categories: Tags:
weighbridge software-weighing software

In this article we will take up weighbridge software. We will try to understand the benefits that you can avail from them. If chosen well, weighbridge software will boost your efficiency of the weighing process.

One of the most important component of your weighing bridge is the software. They add the extra leg to your machine that smoothens or uplift the business processes attached to weighing. Currently most of these weighbridge software are beautifully designed for specific industries. But in general, what benefits that you must look for in the software that you procure.

Three features in weighbridge software to look for

Vehicle Information and tracking –

This is one of the most looked for feature in weighbridge software. The software can keep the stored tare, registration numbers and other details necessary for the trade.

Let us understand how does this feature help in the weighing process.

For loading a vehicle, first we measure the weight of the empty vehicle and then measure the vehicle with the load. If the tare weight is stored, we reduce one step from the weighing process. Even during unloading, the weight of the vehicle measured with the load will suffice to determine the goods weight as the tare weight is already present in the weighbridge software.

As we had mentioned earlier in our article on “errors of weighing”, we must not rely on the stored tare weight blindly and verify the data once in a while by measuring the empty vehicle.

If you have weighbridges at multiple point, the vehicle data serves for tracking purposes.

One of our clients optimised his loading time by tracking the entry and the exit time of the vehicles.

Some of the advance software allows to tag the tracking with cctv camera footage which is also useful in keeping a check.

 

A user-friendly ticketing interface –

There is a high possibility that your weighbridge operator will be spending most of his time here. A clear and easy navigation system of the ticketing interface will make the ticketing process faster. Make sure that auto search while typing feature is enabled to access vehicle information, customers and addresses.

Ease of getting multiple prints is a good option to have it in your ticketing module of the weighbridge software.

A lot of logistic company needs various features like barcode generation, invoicing, auto sms etc. on the ticketing module for easy integration with other business processes as well.

 

Reporting and Backup

Your data is important and if your software can back-up the data on cloud then nothing like it.

Your weighbridge is a source of business intelligence. Reports, hence is a very important aspect of weighbridge software. The software may not be designed for advance reports so option of having the data exported to excel, open-office or a database format will be beneficial. This will help other associated software to analyse your data and derive insights.

 

These are the three features that you must definitely look for in your weighbridge software. A lot many business processes can also be addresses through these software depending on the industry your weighbridge serves.

Weight difference in weighbridges – A realistic weighing scenario in India

Categories: Tags:
weighbridges in indian scenrio

This article will help you understand how to get the best output from your weighbridges in realistic scenario in India. We look into how weight difference in weighbridges is a constant challenge to businesses and how to overcome it.

Having your weighbridge displaying accurate weight is very challenging. Weighbridges are a precision instrument that measures trucks with load. And this is quite a task for instrument that needs to deliver precision.

It is important understand the common practices in regards to the weighbridge. This will give us a clear picture how prevalent is the “weight difference” situations.

You may not have tried this but if you recheck your weighbridge’s calibraweight difference in weighbridges in indian scenariotion with the same weight that was used to calibrate it last time, you will find that there is a weight difference.

Or say you have calibrated your Weighbridge- A against Weighbridge-B a few months back. You have matched the weight measured in A to be same as that of B by nullifying the weight difference between them. If you think that the weight difference of A and B will be same then you might, to a great extent, be wrong.

This does not mean that there has been a mistake in measuring the weight, it simply means that your weighbridge needs a recalibration.

Recalibration is not the challenge. The challenge is when or how can one identify that the weight difference in weighbridge demands recalibration.

Let us look at another very realistic scenario in terms of weighbridge usage that leads to a weight difference in weighbridges.

We have been almost blaring in each of our article regarding the importance of managing linearity issue. We find consistently businesses ignoring it.

You can know more about linearity in this blog better.

If we put it straight forward – You are draining your profits if you overlook non-linearity error in your weighbridge.

The ideal way to get your weigh bridges calibrated is by using test weights. As it is tough to find test weights we rather use a way around.

We calibrate one weighbridge against another with a single truck load. Now the non-linearity in simple terms mean that the weight difference in weighbridges differ with different weight.

The correct way of calibrating weighbridges against a mother weighbridge is to follow a five step process. In the 5 step process the weight difference in weighbridges in full spectrum of its capacity is measured and compared against the mother weighbridge. It is then calibrated against different weight range. This way your weighbridge is covered against the linearity issue.

In case you are getting your load cells replaced make sure that you get pre calibrated load cells.

Depending on the frequency of weighbridge usage it is a good practice to calibrate your weighbridge once or twice in 3 months.

As always stressed, keep a proper maintenance schedule/process of your weighbridge. After all your weighbridge is responsible for the most fundamental process of your business – weighing.

Different errors that can occur in a load cell.

Categories: Tags:
load cell

This article we will discuss the different errors that can occur in a load cell. This is slightly technical and best understood in consultation with your weighing engineers.

The more you understand your load cell the better you can determine the dynamics of weighing.

This article will help you to understand different load cell errors and in turn help you choose the right components and manage the environment that determines the final weight output displayed by your weigh bridge.

Here we will be considering different factors that determine the final output from your load cell. It will be a good idea to consult with your weighing engineers to understand these factors better. As this is going to help to zero down the right load cell that would fit your requirement.

The more you understand your load cell the better you can determine the dynamics of weighing.

Factor-1 – Error amplification

Load cells may amplify an error with increase in weight. This is termed as non-linearity issue.

The impact of this issue can be best understood with an example. When you weigh a load of 200 kg let’s say the error of 10 kg is encountered. We at times assumethat this error is constant. But to our surprise we may find that when we weigh 2000 kg the error is also amplified 10 times. We may have calibrated the weighbridge to nullify 10kg but with 2000kg measurement the error of 90kg still remains in the measurement. This is surely not an error to be neglected.

There are load cells that are pre-calibrated to tackle such non-linearity errors. This is one of the major factor that differentiates load cells based on cost.

As a consumer you may be startled by the price difference of load cells in the market. One major factor that drives the price of the load cell is determined how good a load cell is handling such linearity issues.

Linearity issues is a major factor that determines the cost of load cells

Factor 2 – Hysteresis

Do you know that your load cell may have different reading for the same weigh applied to it? This differdifferent types of errors in load cellence is encountered when the load is increased to a specific weight and second when the weigh is being decreased to that weight. Technically it is called Hysteresis.

This comes in affect when we need to fill a shipment to a particular weight or empty a container toa certain weight.

Most of the load cells are calibrated against hysteresis and linearity issue together and called as combined error.

Factor 3 – Error with time and frequency

Load cells may display some error while repeatedly measuring weight. This is one factor that must be accounted for as well to mitigate any error in the final output.

Load cell also shows difference with time, when the load remains on the cell for a long time. This is called creep effect.

Factor 4 – Temperature changes

Temperature changes the sensitivity of the load cell. Most of the load cells are temperature-compensated to reduce errors.

But if the weighing cycle exposes the load cells to low temperature (at night) and high temperature at day time is wise to account for errors due to temperature change.

 

Load cell maintenance of your weighbridges

Categories: Tags:

Your weighbridge is a huge machine. It can take the load of heavy trucks for your business needs. But what needs to be understood is that at the end of the day, your weighbridge is a precision instrument. The core functionality of the weighbridge of providing the correct weight is possible due to the load cells present in it. This article will serve you as the load cell maintenance guide.

 

Load cell maintenance and why do you need it –

 

We have talked a lot on how weighbridge errors can steal away your business profitability earlier. Faulty load cells can be a major reason for the same. So for your weighbridge to perform uniformly, your load cells need to be serviced and calibrated periodically from a competent company.

load cell maintenance for weighbridges

 

 

What are the safety tips for load cell maintenance –

 

  1. Keep the weigh bridge clean – Your weighbridge will age faster if it is not relieved of the dust and mud. Make it a point to keep the weigh bridge clean. Use an air blower to keep the area across load cell free of dust.

 

  1. No flooding – Make sure that you have an efficient drainage system to get rid of the water from the pit. Water and moisture poses threat to your load cell.

 

  1. Welding is not cool – Just let us know in case you need any welding repairs to be done on your weighbridge. Do not try to do electric welding on your weighbridge by a welder. As the welder may not know how to get the welding done without destroying the load cell. Welding requires high current and that can destroy the load cell easily.

 

  1. No compromise on electric source – Weighbridge needs a stable and a good quality power source. Providing a dedicated and stable power source will be a good idea to provide a long life for your machine. One better way is to avoid sharing the power source which is attached to machinery that destabilises power.

 

  1. Do not avoid servicing – Servicing is insurance towards getting quality output from your weighbridge. Tie up for an annual maintenance with a competent company and be assured of good health of your weighbridge.

  1. Calibration – Calibration is an important aspect of your weighbridge. In fact you are legally obliged to maintain accuracy of your weighbridge in case you are using it for business purposes. You can also go through our article which deals with calibration and maintenance of your weigh bridge. As a rule of thumb calibrate your weighbridge in case you have repaired or replace components like load cells or weight indicator.

 

NOTE: It is usually a trend in organization to calibrate their weighbridges against a common weighbridge. Let’s call it the mother calibration for the organization. It is advised to calibrate that weighbridge against light, medium and heavy categories of weight.

 

Example. For a 60 ton weighbridge –

Light weight is: 5to 10 ton

Medium: 20 to 30 ton

Heavy: 50 to 60 ton

 

This is recommended to avoid linearity problems. if you do get your weighbridge calibrated with only one vehicle because of unavailability at site it will cause weight difference later and it will trouble you. Though the best way is to perform with right test weights for the whole procedure but is rarely possible as it’s not available.

 

We have been helping organizations to weigh accurately since 5 decades. You can write to us or comment us below and we will be glad to help you.

 

Owners guide for weighbridge maintenance

checklist weighbridge maintenance

 

 

Your weighbridges work in a very tough environment. Dust, water, slurry, debris are its common impediment to your correct weigh measurement. And to ensure accuracy and reliability of your weighbridge, periodic maintenance is a necessity. We have been stressing how “weighing” is the fundamental of the business process, this insists us that weighbridge maintenance must be a habit that organizations must develop.

 

 

  1. Make it a habit –

    Your weighbridges are exposed to lot of dust, mud, water etc. These are not so favourable to the accuracy of your measurement. The exposure depends a lot on the kind of industry your weighbridge serves. But the fundamental remains the same. Accurate weighing is a demand of every industry your weighbridges are in. We have discussed extensively as how it hits the profit directly if you lose your weight against weighbridge errors.  It pays to organization in a long run that put an effort to make sure their weighbridges are cleaned regularly. Invest on the equipments that help you clean your weigh bridges. Having a water supply close by for a jet clean and a pump to drain out water from pit is a profitable habit for owners of weighbridges

NOTE: Jet cleaning may not be suitable for your load cells in case they do not belong to the protection class IP69K. You can use air jet instead of water jet for cleaning.

 

  1. Periodic Cleaning –

  1. On daily basis – This is to get you weighbridges ready for its daily operation. Make sure the water is pumped out in case the pit is filled with water due to rain. Or make sure to get the dust off the load cell after a windy day with air blower. This is better done with a checklist depending upon the environmental condition and the industry your weighbridge is subjected to.
  2. Fort night – This is to make sure that the weighbridge is not affected by any sort of errors due to debris etc during the two weeks of operation. Edge-middle-edge test is a good way to understand that. Measure the weight of the truck placing it at the middle of the weigh bridge. Now take the weights placing the truck more towards the front, then towards the end, then to the side edges. Note the weights during all such positions and see if there are any variations in the weight.
  3. Monthly habit – Jet clean (use water only if your load cell can resist jet-water cleaning else use air jet instead) your weighbridge and give a close check up to identify any damages on the platform or load cells. Arrange for any rectification your weighbridge demands.

 

  1. Advance cleaning –

    Make sure to get your weighbridges cleaned by professionals. We recommend our clients to go for such advance cleaning one after the rainy season. This process becomes much easier and without a headache for clients with AMC.

We are keen to hear from you your weighbridge maintenance challenge. Let us know and we can help you to resolve it. You can also share how you have been able to keep your weighbridge healthy in our comment section for everyone’s benefit.

Who is stealing your weight?

Categories: Tags:

The most fundamental element of manufacturing, delivery, procurement and production is – Weighing.

We keep this repeating in an alarming rate because we do not want you to miss the point. The weight of the trucks measured determines profitability or loss for your business.

Take it this way – Your business needs you to get 10 trucks of load to your factory. You measure the weight and clear the material for production. What you missed is the 200Kg calibration error your weigh bridge has inherited in a span of time. In a month you end up losing 6000 kg of raw material for production.

That indeed is a loss.

If you lose weight, you lose money. That’s the fundamental.

 

We will take up 4 scenarios to help you understand the hidden thieves that keep stealing your weight. So lets see the causes of error in measurement of weight in weighbridges –

 

  1. Position Matters – A truck scale or a weighbridge is a platform where the truck is driven in to measure its weight. The platform where the truck stands have load cells below it. These load cells send electrical signal to a junction box. The junction box calibrates it and displays the weight. Simple isn’t it?

It is to note that the same truck would weigh different if the truck is not placed on the platform correctly. The truck would not weigh correctly if it is more towards the edges. That is called corner difference and that is an error.

Make sure that the error is nullified and so that the truck weighs the same if placed on the platform be it edges or in the middle.

 

  1. That pit has dirt / water – The two major factors that steal the weight where maintenance is a challenge – Dirt and Water. If your pit has water or the load cells are covered with dust, it is very likely that the weight-thieves are right down there and needs to be removed.

 

  1. The feel-good calibration – Nothing hurts business more than a process that is out-rightly wrong. We get request to calibrate a weighbridge based on another weighbridge. Why? –
  • Because when the load comes from point A to point B they have to be same. As the weighbridges in point A and B are located far apart and when there is a fair transportation how can the truck measure different in both the points.
  • Because one of the weigh bridges is calibrated, we can just calibrate others based on this one.

The efficient practice is to get your weigh bridge calibrated with proper weights and get certified. Simple!

Go for pre calibrated digital load-cells as that will reduce the effort of getting standard weights

NOTE:  it is very difficult and literally cumbersome to get more than 15 tons of test weight

4. The business of re-calibration – The habit of matching the weight of the load of the trucks leads to multiple re-calibration of the weighbridge by the person doing the weight reading. This is a nasty practice in businessand causes the maximum amount of weight theft. And this is the exact reason why we introduced anti-theft within our weigh bridges. This mechanism not only prevents the re-calibration but also monitors the re-calibration (attempts) made. We provide a dynamic locking password which is not a standard so cannot be known by anyone. It is software based and should be only given to a trustworthy person.

NOTE: If you let out the mechanism publicly to all staff then you can never know what is happening with your weight of the weighbridges.

In case you would like to know how we can reduce weigh thefts with our anti theft mechanism then – tap on – Tell me about Anti theft mechanism in weigh bridges.
