Explosion-proof electric contact pressure gauge Beijing electric contact pressure gauge Explosion-proof electric contact pressure gauge manufacturer Explosion-proof electric contact pressure gauge price Explosion-proof electric contact pressure gauge Content introduction:
Explosion-proof electric contact pressure gauge produced by Beijing Pute Instrument Complete Factory >> 1. Overview:
The explosion-proof shell of the explosion-proof electric contact pressure gauge has good explosion-proof performance. Therefore, the explosion-proof electric contact pressure gauge can withstand the explosive gas inside the shell in addition to the influence of sparks or arcs during normal operation. The mixture is outside the explosion pressure generated when an explosion occurs 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 detection component: (
The elastic deformation of the spring tube in the measurement system
The elastic deformation of the spring tube in the measurement system drives the contacts in the electrical contact group to produce corresponding Action: (
Closing or opening
To enable the circuit in the pressure control system to be connected or disconnected to achieve the purpose of automatic control of alarms and on-site instructions.
Press. "Explosive Environment It is designed in accordance with the relevant regulations and standards of "General Requirements for Explosion-Proof Electrical Equipment" and "Explosion-proof Electrical Equipment for Explosive Environments Explosion-proof Electrical Equipment D" and manufactured with drawings and technical documents approved by the nationally designated inspection agency.
The explosion-proof category of the explosion-proof electric contact pressure gauge is Class II explosion-proof type group, and its mark is dⅡ.
The explosion-proof electric contact pressure gauge is suitable for measuring non-crystalline and non-solidified explosive properties in places with explosion hazards. Mixture or various non-explosive medium pressure.
2. Structural principle:
The explosion-proof electric contact pressure gauge is composed of a flameproof shell, a measuring system, an electric contact group, a regulating device and an outlet box.
