GMY400Bolt and Cable Stress Sensor
The bolt and cable stress sensor employs strain measurement technology to measure the vertical load stress in coal or rock masses. Under stress, the coal or rock mass deforms, transmitting the stress to the strain body, which also deforms. The strain gauge converts this deformation into a voltage signal. The force gauge is controlled by a single-chip computer and integrates multiple functions such as digital display and clock. It features a compact size, high precision, easy operation, low power consumption, and portability. Its unique low-power design allows it to be powered by dry batteries. The GMY400 bolt and cable stress sensor detects, processes, and displays the pressure signal of the sensor through a microcontroller.
