Pressure gauge with good explosion-proof performance

Explosion-proof electric contact pressure gauge consists of explosion-proof housing, measuring system, electric contact group, regulating device and outlet box. The explosion-proof shell of the pressure gauge has good explosion-proof performance. Therefore, the explosion-proof electric contact pressure gauge is not affected by sparks or arcs during normal operation. In addition to being able to withstand the explosion caused by the explosive gas mixture inside the shell, outside the explosion pressure, and can effectively prevent the resulting heat energy from spreading smoothly outwards, but can only slowly spread outwards along the tiny gaps inside the shell along the explosion-proof joint surface. At this time, the instantaneous temperature transmitted to the outside of the shell has dropped below the ignition temperature of the explosive gas mixture, so it will not cause an explosion. The working principle of the explosion-proof electric contact pressure gauge is based on the…
