This electric contact pressure meter is designed according to GB3836.1. B83. The general requirement of the explosion-proof electric equipment on explosive environment, and GB3836.2. B3, the explosion-proof electric equipment and flame-proof electric equipment on explosive environment. Meanwhile, it is manufactured according to the chart and technique document approved by the identified testing organization.

The explosion-proof type of meter is kind B grade T4 Group. The mark is Exd II BT4.

The meters can apply to measure pressure of non-crystal and non-concretion explosive intermixture or diversified no-volatile medium.

The meters could automatic control and signal alarm if they work in the electric apparatus parts with explosion-proof or other safety(for example, relay, contactor, etc. )
