Strain gauge cells are the life of the industrial bridge weighing systems.

The load cells remain very reliable and accurate even after the weight bridge operations that are conducted in harsh climatic conditions.

To develop these cells is not an easy task and there are no easy ways. But,Strain gauge load cell- The life of high performance in bridge systems Articles there are several companies that try to develop the cheaper version of these products by cutting the corners and compromise with the quality. When short circuiting is used in any of the load cells, then the quality will suffer. Due to this the low quality cells never meet the required criteria for the bridges and they have a high quality of ownership for the bridges. The low quality enters the markets and unreliable manufacturers capitalizing on this by selling low quality products. From the appearance, the strain gauge load cell appears to be the same and then the similarity ends there itself. The problem arises when the manufacturers develop a load cell for the weights and perform the task very nicely. This is where the problem arises when other manufacturers are not able to deliver that level of quality.Here are some factors that are necessary for the manufacturers to look into and develop high capacity load cell-Optimized environmental sealingHigh quality material properties and heat treatment for critical load componentsWell manufactured loading and testing procedures100% product testingMechanical designThe mechanical design for the load cell is very important. The procedures of testing can make the performance better, but the original design must be very good. The design must be such that it can work effectively in the working environments. It must be such that the product must be tolerant towards off-axis, side, and angular loading etc. It must also ensure environmental sealing to avoid premature damage due to cable entry.Material SpecificationA strain gauge load cell works in a high density environment where the load must be repeatedly loaded and unloaded. Due to this the material selection and heat treatment for measuring the device also play a vital role.Strain GaugesThe gauge must match with the load measuring equipment particularly where linear characteristics are required.TestingThese cells have independent characteristics, so every cell must be repeatedly tested to avoid any kind of damage or problem. The process of testing must also include load cycling and temperature testing. If you want to know about pile test visit us online.
