GPD(D) Series Mining Explosion-Proof Multi-Channel Pressure Sensor
The GPD(D) series mining explosion-proof multi-channel pressure sensor integrates eight calibrated digital sensors, processing signals into digital values while monitoring sensor status. Data such as sensor ID, pressure, status, and temperature is transmitted via CAN or RS485. With two wire exits for easy parallel connection, multiple units can share a single cable, reducing installation space and maintenance costs. Housed in a stainless steel explosion-proof enclosure (Exdb Ⅰ Mb), it complies with GB/T3836 standards.
