The GPD60 hydraulic support pressure transmitter is a new type of pressure transmitter specifically designed and manufactured by our company for comprehensive mining equipment in coal mines. It consists of a high-stable strain gauge pressure sensor paired with a high-performance dedicated amplifying circuit, encased in a stainless steel shell. The GPD60 design meets safety requirements for underground hazardous environments, boasts a robust structure, withstands strong impacts and vibrations, and has strong anti-electromagnetic interference capabilities. The GPD60 pressure transmitter is suitable for use in flammable and explosive environments and is designed for detecting and controlling fluid pressure in mines with risks of gas and coal dust explosions.
The hydraulic support electrical control system for coal mines is now widely applied.
