Compression Load Cell, Column type, 15 ton/30 ton/50 ton to 200 ton
fter purchasing one RJ load cell, you can buy a special digital panel meter to obtain readings directly, or buy a transmitter to output standard signal to PLC, DCS and other systems. Customized output signal is 0-5V, 0-10V, or 4-20mA.
Note: The load cell cannot be connected to both the transmitter and the controller at the same time — only one can be selected.
Compression load cells have capacity range from 15 ton, 20 ton, 30 ton, 50 ton, 100 ton to 200 ton. Load cell capacity can be customized according to customer requirements.

Wiring Method
Tips: Load cell working principle
Load cell is actually a kind of device to transform the weight signal into the measurable electrical output signal. At present, the commenly used load cell is the resistance strain load cell, which utilizes the principle that the resistance modifies accordingly when the strain gauge deforms. Load cell is mainly constituted by four parts, which are respectively the elastic component, strain gauge, measuring circuit and transmission cable.
