Details
The bidirectional wind speed sensor for coal mines is a fixed intrinsically safe sensor suitable for measuring wind speed and wind direction in underground ventilation tunnels, air vents, fan shafts and other tunnels in coal mines. The sensor adopts the pressure difference principle and has the advantages of no moving parts, high reliability, wide operating temperature range and high accuracy. In addition, the sensor uses infrared remote control adjustment to avoid interference with the flow field around the sensor during the calibration process, making the calibration more convenient and accurate.
