PS sensor is designed for liquid pressure measurement in hydraulic drives, e.g. in longwall powered supports. It is designed for installation in underground workings of mines with methane and/or coal dust explosion hazard. Communication with the sensor is via RS485 interface. PS sensor is an intrinsically-safe device attached with type EC test certificate no. OBAC 14 ATEX 0123X (where X stands for specific application conditions -10ºC≤Tamb≤+40ºC).
