Compression Load Cell, 300kg/1000kg/25 ton/50 ton to 100 ton
After 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, 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.
The compression load cell is a device used to measure pressure changes. Its working principle is based on the Piezoresistive Effect. When pressure is applied, the piezoresistive material physically deforms. This deformation causes the material's resistivity to change, producing a voltage signal. By measuring changes in this voltage signal, information about pressure changes can be obtained. Compression load cells have capacity range from 300kg, 500kg, 1000kg, 10 ton, 25 ton, 50 ton to 100 ton. Load cell capacity can be customized according to customer requirements.

Tips: Can Compression Load Cells be used in multi-load measurement systems?
Yes, compression load cells can be used in multi-load measurement systems where multiple load cells are combined to measure forces in different directions or parts of a system. In such systems, the data from multiple load cells are combined to provide an overall force measurement, often used in testing or monitoring systems in industries such as aerospace, automotive, and structural engineering. For instance, in large-scale testing setups, multiple compression load cells are used to measure different parts of a structure or machine under load, allowing for more comprehensive force measurement.
