Product Description


Application description

This explosion-proof electric junction prod pressure meter is designed according to GB38361.B83,the general requirement of the explosion-proof electric equipment on explosive environment, andGB3836.2.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 meters is Ⅱ kind B grade T4 Group. The mark is ExdⅡBT4.

The meters can apply to measure pressure of non-crystal and non-concretionexplosive intermixture or diversified novolatile 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.).

Main technology data

Precision grade: 1.6.

Scale range:



Control mode: upper and lower limit slow action junction switch. 

Maximal working voltage: DC220V or AC380V.

Contact power: 10VA.

Working position: vertical setting. 

Using condition: -10-50°C, relative humidity not exceed 80%, the explosive intermixture should lower than Ⅱkind B grade T4 Group, working oscillation and the medium pulsation should have no effect on meter action.

Temperature effect: displayed value will not exceed 0.4%/10°C, setting point will not exceed 0.6%/10°C(using temperature deviate 20±5°C).

Weight: 6Kg.


The meter is composed of flame-proof shell, measuring system,electric junction group, adjusted device and outlet box.

The flame-proof shell of the meter has favorable flame-proof performance. It can not only stand the explosion pressure of the explosive intermixture in the shell but also prevent the heat energy form diffusing.The energy can only gradually and slowly diffuse along the cranny of the explosion-proof connection.The instant temperature transmitted to the outside has been reduced to under the ignition point of the explosive gas intermixture. So the explosion will not happen.

The working principle of the meter base on measuring the flexibility of the component, drive the contact in the electric junction group act through the mechanical transmission (open or close) in order to turn-on or break the circuit of the controlling pressure system. So it can realize automatic control alarm and spot indication.
