The mining pressure sensor is an intrinsically safe instrument suitable for monitoring the negative pressure and atmospheric pressure of underground tunnels and gas extraction pipelines in coal mines. It is mainly used for monitoring wind pressure changes to ensure the normal ventilation, air distribution and gas extraction pipeline safety of the mine. The sensor circuit adopts a single-chip microcomputer design, which can display the detected pressure value on the spot and output frequency signals or RS485 digital signals for remote collection; it can remotely adjust the zero point and sensitivity, which brings great convenience to use and maintenance. Explosion-proof mark: mining intrinsically safe type, explosion-proof mark: Ex ia Ⅰ Ma.
