What is the function of explosion-proof electric contact pressure gauge?

The main function of the explosion-proof electric contact pressure gauge is to measure the pressure of non-crystalline, non-solidified explosive mixtures or various non-explosive media in places with explosion risks, and can be used in conjunction with electrical devices with corresponding explosion-proof performance or corresponding safety measures to achieve the purpose of automatic control and signaling (alarm) to the controlled system.
Specific functions include:
Pressure measurement: Suitable for measuring the pressure of gas and liquid media that are not corrosive to copper and copper alloys.
Automatic control: When the pressure reaches the set value, the movable contact of the electric contact pressure gauge comes into contact with the contact of the setting pin, connecting the circuit to control the start and stop of the compressor motor and other equipment.
Alarm function: When the pressure exceeds the normal range, an alarm can be issued in time to remind staff to take measures.
Explosion-proof performance: The explosion-proof shell can withstand the explosion pressure generated by the explosive gas mixture inside the shell when it explodes, and prevents the resulting heat energy from spreading smoothly outward, thereby preventing the explosion of the external explosive mixture.
In addition, explosion-proof electric contact pressure gauges also have the advantages of reliable action, long service life, and large contact switching power. Different types of instruments can be selected according to different use requirements, such as ordinary type, anti-corrosion type, and shock-resistant type.
