Split-type bidirectional wind speed and air volume sensor for mining is a fixed intrinsically safe sensor suitable for measuring wind speed and wind direction in 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.

It is suitable for coal mines containing explosive mixtures but no corrosive gases that damage insulation.

Explosion-proof type: mining intrinsically safe type, explosion-proof mark: Ex ia Ⅰ Ma.

The sensor has a reverse wind direction alarm function;

The sensor should be able to set the alarm point arbitrarily within the measurement range, and the difference between the alarm value display value and the set value should not exceed ±0.2m/s; 

The sound level intensity of the alarm sound signal at a distance of 1m should be no less than 80dB (A);

The light signal should be clearly visible at a distance of 20m in the dark.
