The Selection of the load cell is such a difficult task…But not to require worry about it; this write up would help you to choose the right one…
First have look about some aspect that should be determined before to selection procedure.
- Decide the utmost load ,weight or force that you want to measure
- Capacity with response to the application
- Accuracy level as per requirement
Normally it is the device that control the force or measure weights of different objects thus you require the decide the deadline figures for some factors. Such as the maximum load, predictable weight as well as what would be the maximum force that you want to measure or control by the existing device. Once you decide these things we are able to move forward to next step in the selection process. We have already concluded the applicable force or weight for our application; currently you have to pick the load cells which is suitable to the on hand application because there are different options available with response to the different applications.
The next step is the most important critical part, because the most significant application of the said device is precision. Individuals are pursuing it only for its highly accurate working procedure. You have to choose the load cell accuracy level as per your allpication; just a simple example you are providing it to the manufacture of jewelry weighing scale manufacturer you require the extremely accurate with zero tolerance; same for other side if it is for any industrial scale manufacturer which are used to measure the weight of machines or goods that require the low exactness level.
Some time the loading situations would exceed the determined capacity of load cells; at this type of conditions the overload protection is essential for any system. You should must check the overload protection is provided or not manufactures specifications.
Hope this would be helpful to you…!!!

The present scenario, the electronic weighing machines are basic need of the every most minuscule shop. It is widely use for the applications where the high precision is the paramount factor such as jewellery shops; the load cell is the most significant part of this types of highly accurate electronic weighing scales. Actually load cell is the sensor that senses the force or weight of the object and after I that it provides the output in digital indicator.
Essentially this is one type of transducer that converts the mechanical force in to the digital result. Let’s have some detailed knowledge about the working principle of the said device.
Basically the load cell works on Wheatstone bridge theory. The Wheatstone bridge is an electrical circuit having the two parallel voltage divider circuits basically utilizes to measure the unidentified resistance.
R1 & R2 is the first and R3 & R4 is the second voltage divider circuit. The output would found at the middle nodes of the both voltage dividers. These circuits are able to sense the negligible variations in resistance that is the reason for the unbeatable accuracy. The load cells is not only use for weighing machines but also widely use in load testing equipments, industrial scales and many others. The some of the utilities of the existing machine are as per below.
• It is broadly cell utilized for the research, expansion and testing of the newly designed machine or device; the load sensing is used to determine the operational forces, structural capability of equipment and overload potential.
• The enclosed sensor is capable to sense the smallest variation of values respect to the specified true value to it; for the reason that it is the best suitable device for calibration devices.
• This are also vastly use in jewelry shops where the negligible difference is not acceptable.
It is capable to deliver the extremely accurate result compare to any other devices ; thus because the unique features this are becoming more and more recognized instrument for testing of various equipments, for precise weighting systems, For press pressure control and many other applications.
