GPD5(A) Mine Differential Pressure Sensor

The GPD5(A) mine differential pressure sensor is an intrinsically safe instrument suitable for monitoring the air pressure of ventilation systems of coal mines. It is mainly used to continuously monitor changes in the pressure inside and outside the ventilator room, air leakage of old tanks, and tightness of partitions.

Product overview

The GPD5(A) mine differential pressure sensor is an intrinsically safe instrument suitable for monitoring the air pressure of ventilation systems of coal mines. It is mainly used to continuously monitor changes in the pressure inside and outside the ventilator room, air leakage of old tanks, and tightness of partitions.

With a single-chip microcomputer, the sensor circuit is capable of locally displaying the pressure and sending various signals for remote collection. The zero point and sensitivity can be adjusted remotely. In addition, the system has the functions of fault self-check to facilitate the use and maintenance.
