一、 用途

I. Purpose

隔爆型电接点压力表的防爆标志你：ExdⅡCT4（标志Ex、隔爆型d、类型ⅡC、温度

The explosion-proof marks for Explosion-proof Type Pressure Gauge with Electrical Contact are as below: ExdIIC T4 (in which the Ex stands for mark, d stands for explosion-proof, IIC stands for category and T4 stands for temperature arrangement),

组别T4），适用于爆炸性气体环境中，测量温度低于70℃的介质压力。并通过电气信号装

which is applicable to the explosive gas environment with media pressure at 70 ℃ and below measured temperature.

置与具有相应防爆性能的电器件配套使用，对被测压力执行自动控制、报警、信号远传等多

The explosion-proof Type Pressure Gauge with Electrical Contact is equipped with multi functions as automatic control, alarm, signal distant transfer and other functions for the measured pressure with the help of the electric signal equipment and electrical equipment with the related explosion-proof performance for. The grade of gauge case is for IP65.

种功能,防护等级IP65。

二、 仪表结构与防爆原理

II. Gauge Structure and Explosion-proof Principle

仪表由隔爆结构的外壳及内装电接点压力表组成。工作中，当表壳内部的可燃性混合物

The gauge is composed of explosion-proof case and build-in pressure gauge with electrical contact. When the flammable gas mix in gauge case explodes caused

因受火花或电弧（电接点压力表的电气信号装置所引起）等作用而发生爆炸时，不会引起仪

by the spark or electric arc (generally caused by the electric signal device with pressure gauge with electrical contact),

表外现场爆炸性气体的爆炸，从而达到防爆的目的。

the explosive gas outside the case won’t explode accordingly, thus achieving the explosion-proof purpose.
