SL-RC3 Compression load cell
Product description：
SL-RC3D A typical standardized column sensor with high cost-effectiveness, using a small-sized thick metal processed sleeve and a fully welded sealing process for the upper and lower cover plates, which enables the sensor to work normally in very harsh environments. The rocking column design ensures the optimal performance of weighing accuracy, and the weighing equipment can still maintain a good level of accuracy even when the weighing platform generates biased loads and lateral forces when moving forward, backward, left, and right.
Main Features：
Material: Alloy and stainless steel
Hermetically sealed to IP68
Self-restoring column design
Wide range of capacities from 7.5t through to 300t
High input resistance
Calibration in mV/V/Ω
