Tag: load cell

Load cell is based on the principle that resistance changes when the resistance strain gauge pasting on the surface of elastomer is forced deformation. Load cell converts the change of resistance to mV signal so as to complete the process of converting external force into electrical signal. According to its principle and structure, the fault of strain gauge load cell is often caused by some human or natural factors.

The calibration of load cell and digital display controller is mainly to confirm the weighing signal of zero point and full range of the load cell. That is to say, telling the digital display controller what are zero weight signal and full range weight signal received from the load cell. In this way, the digital display controller will display the value according to the detected weight, or export the matching weight signal to the PLC/DCS control system.
