| Zusammenfassung: | The utility model provides a mine explosion-proof pressure sensor. A thread at the detection end of a pressure transmitter is in screwed connection with a thread in a counter bore; the upper end of an upper cover is fixedly connected with the lower end of a cable communication joint; an elastic sealing ring is arranged on the lower part inside the cable communication joint; a compression nut is in threaded connection with the cable communication joint; and a gasket is arranged between the elastic sealing ring and the compression unit. According to the mine explosion-proof pressure sensor, the pressure signal and the electric signal of an ordinary sensor are subjected to explosion-proof processing according to underground electrical appliance specification requirements, so that the sensor is completely isolated from explosive gas, the explosion-proof requirement is met, and the explosion-proof transmission process of the pressure signal and the electric signal to be detected is finished. Accordingly, the mine |
