Details
Mining intrinsically safe drilling stress sensor is mainly used for the detection of rock stress in coal mines. It has the characteristics of small size, easy operation, intuitive display and strong data processing function. The sensor adopts RS485 communication method to transmit the monitored pressure data to the mining intrinsically safe data transmission substation in real time, and then transmits it to the mining information transmission interface on the well through CAN communication method. The transmission interface transmits it to the server through RS232 communication method for stress data analysis and processing.
