UTILCELL / 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
