GFY15X Forward and Reverse Wind Speed Sensor for Mine
The GFY15X forward and reverse wind speed sensor for mines is an intrinsically safe fixed sensor suitable for wind speed and direction measurement in underground ventilation roadways, air inlets, wellheads (with fans) and other roadways in coal mines. Using the principle of differential pressure, the sensor has the advantages of no moving parts, high reliability, wide operating temperature range and high accuracy. In addition, the sensor can be calibrated with an infrared remote control, thus avoiding the interference to the flow field around during calibration, and making calibration more convenient and accurate.
With a single-chip microcomputer, the sensor circuit is capable of locally displaying the wind speed. Moreover, the sensor has multiple signal output modes for remote collection. The power supply circuit of the sensor is a switching power supply, to reduce the overall power consumption, which is beneficial to increase the transmission distance between the substation and sensor.
