Application
The instrument is suitable for measuring non-tethered explosive mixtures or various non-explosive medium pressures in locations where there is a risk of explosion. The meter can be used with the electrical components (such as relays and receivers) that have corresponding explosion-proof performance to take corresponding safety measures, so that the controlled system can realize automatic control and signaling (alarm).
The meter has measurement control. The upper and lower control pressure values can be arbitrarily set. The action is stable and reliable, and it is widely used in industrial enterprises such as petrochemical, power station metallurgical water supply and electromechanical equipment.
Structural principle
The instrument consists of an explosion-proof enclosure, a measuring system, an electrical contact set, a device, and an outlet box.
The flameproof enclosure of the meter has good flameproof performance. Therefore, in addition to being able to withstand the explosion pressure generated by the explosive gas mixture inside the casing in the event of an explosion during the normal working process, it can effectively prevent the heat energy generated from spreading smoothly. However, only when the inside of the bald body spreads slowly along the tiny can image of the explosion-proof joint surface, the temperature passing to the outside of the casing has been lowered to below the ignition temperature of the explosive gas mixture, so Will lead to smoke
The working principle of the meter is based on the elastic deformation of the detecting element (the spring tube in the measuring system). The mechanical transmission causes the contacts in the electric contact group to generate corresponding actions (closed or opened to enable the circuit in the pressure control system to be Turn on or off to achieve automatic control of alarms and on-site instructions.
