Weighing scales come with load cells, an integral part that helps in measuring the weight. As load cells are internal parts of weighing scales, many people do not know much about them. Load cells are imperative and they serve crucial functions. Sometimes in a while, these load cells need to be replaced. In order to replace them properly, you need to understand the basics of load cells.
The basic structure of a load cell is simple and only consists of spring elements and strain gauges. If you look into a high-quality load cell from China, you will see the same kind of structure. The spring is often made out of aluminum or steel which makes it sturdy and elastic. The function of a spring element is to get suppressed with the application of weight and get back to the normal state with the withdrawal of the weight.
Though most of the times the change in shape of the spring element with the application of weight is minute but can be traced with a strain gauge. The deformation of the strain gauge is interpreted with the help of electronics and the weight of an object is finally measured.
How do load cells get affected by environmental conditions?
The climate and environment in which the load cells are used play a great role. A number of factors can change the accuracy of a load cell from China and bring discrepancy in the weight measurements. The ambient temperature sometimes significantly affect the weight readings coming from a load cell. This is due to that fact that with temperature change, every material changes its shape and load cells are no exception. To eliminate the discrepancy and error caused due to ambient temperature in different parts of the world, the weighing equipment uses temperature compensation mechanism to eliminate errors.
What are the main types of load cells available in the market?
There are a number of load cells that vary in their shape, size, and most importantly their application. The usually used ones are:
• Single point load cells – Single point load cells are generally found under platforms that are loaded with weight on top of them.
• Compression load cells – these load cells can be found under a steel structure that is burdened with weight from on top. These load cells are typically made to withstand heavy weight.
• Bending beam load cells – These load cells are just like the compressive ones but the only difference is that these do not have the extreme weight bearing capacities.
• Tension S-type load cells – These load cells work differently. The weight is suspended from these cells instead of placing the weight on top.
Conclusion – Load cells are extremely crucial parts of each weighing scale. Before buying a new load cell from China or replacing the old ones in your existing weighing equipment, you need to learn more about them. There are different types of load cells available in the market and you should be careful before buying one as a number of factors should be kept in mind. Therefore, it is advisable that you buy load cells from trusted manufacturers like the one from China named HiWEIGH. They provide an array of different load cells that are crafted in a way to meet industry standards.
