Product Introduction
It is used to measure the pressure of non-crystalline, non-solidified explosive mixtures or various non-explosive media in explosive dangerous places.
The explosion-proof electrical contact pressure gauge is designed in accordance with the relevant regulations and relevant standards of GB3836.1 83 "General Requirements for Explosion-proof Electrical Equipment for Explosive Environments" and GB3836.2 83 "Explosion-proof Electrical Equipment for Explosive Environments and Explosion-proof Electrical Equipment "d"" , And manufactured by the drawings and technical documents approved by the inspection agency.
The explosion-proof category of the instrument is Class II explosion-proof type B Class T4 group, and its mark is Exd II BT4.
The instrument is suitable for measuring the pressure of non-crystalline, non-solidified explosive mixtures or various non-explosive media in explosive places.
The instrument is used in conjunction with electrical devices (such as relays and contactors, etc.) that have corresponding explosion-proof performance or take corresponding safety measures to achieve automatic control and signal (alarm) purposes for the controlled system.
