Simulation of weight on a load cell

Hello everyone, I would like to share a concern that I have. I work in the field of truck scale engineering, and what we typically do is measure the output voltage in the signals of the load cell. All readings are in millivolts. For example, at zero kilograms, we have readings of 1.8 mV, and at 3000 kilograms, we have readings of 3.6 mV. These are just numbers, not the actual weight. However, sometimes we encounter issues with some scales, particularly when the load cell shows faults after 10 or 20 tons.

I would like to know how I can simulate the weight on a load cell, receive the data, and determine if it is in good condition or not. We usually realize the problem when we send a truck with 50 tons and perform tests with real weight. Now, I want to provide a tool for technicians to simulate the weight and determine the current status of the load cells.

Do you want to simulate the load at the mechanical or electrical levels?

 

If mechanical, you can use hydraulic jacks to replicate the force equivalent of the truck weight.

 

If electrical, you can replace the load cell with load cell simulator to simulate a load.
