Model MH1 is a heavy duty general purpose compression load cell particularly well suited for hopper and tank weighing and many other large scale industrial applications, including weigh bridges for truck weighing. The simple, compact column design and rugged hermetically sealed construction of the model MH1 load cell assures its long term life in all types of field installations. The model MH1 load cell is often used in multi-cell installations, therefore its standard output tolerance is within 0.1%. The two additional sense wires feed back the voltage reaching the load cell. Complete compensation of changes in lead resistance due to temperature change and/or cable extension, is achieved by feeding this voltage into the appropriate electronics.
