GUD300 Roof Displacement Sensor for Coal Mines

GUD300Mining Roof Displacement Sensor—

The roof displacement sensor is a device used to monitor the displacement generated during roof rock layer separation, roof movement, and roadway shifting. It is primarily suitable for roadway roofs supported by bolts and anchor cables, as well as working faces where roof displacement measurement is required. This instrument features high precision, light-controlled display, and easy installation, making it an essential tool for coal mine pressure monitoring.
