Column Sensor/ SM4 Column Sensor
Product Categories Column sensor
SM4 column load sensor is designed for pumping well power diagram test. It is a load sensor with high anti-interference performance. The product adopts standard mv signal output and fully sealed design, and can work in harsh environments such as high temperature, high cold, high humidity, and high radiation. It is currently widely used in pumping well power diagram measurement systems. It is widely used in major oilfield pumping wells, bare rod force measurement, truck scales, track scales, hopper scales, and other metering equipment.
