ADOS气体变送器GTR 196系列介绍

Application

The gas transmitter ADOS GTR 196 is suitable for continuous measurement of gases in normal areas and areas where there is a risk of explosion.

By employing 6 different types of sensor, noxious, explosive and non-combustible gases and vapours can be measured.

A current signal is generated that is proportional to the measured concentration of gas, which is transmitted to an evaluation unit placed in a safe area, away from any dangers of explosion.

The type test of the explosion-protected gas transmitter, is completed by the KEMA.

Test certificate: KEMA 03 ATEX 2403 X

Degree of protection: II 2 G, Ex demb [ia] IIC T6

Fields of Application

Chemical industry

Manufacture of paints and varnishes

Plastics processing plants

Sewage works

Gas-fired boiler systems

Liquid gas storage houses

Laboratories

Oxygen concentration measurements

Refineries

Cold storage houses (Ammonia monitoring)

Paint spraying booths

TOX sensor

The TOX sensor is a measurement system with an electro-chemical cell, where the sampled gas is measured by diffusion. In the case of oxygen measurement the oxygen content is reduced in an electrolyte, thus producing a small flow of current (electro-chemical process). At a constant air pressure, this current is directly proportional to the oxygen concentration in the sampled air.

应用

ADOS GTR 196 气体变送器适用于正常区域和存在爆炸危险区域的气体连续测量。

通过使用 6 种不同类型的传感器，可以测量有毒、易爆和不可燃气体和蒸汽。

生成与测量的气体浓度成正比的电流信号，该信号被传输到放置在安全区域的评估单元，远离任何爆炸危险。

防爆气体变送器的型式试验，由 KEMA 完成。

测试证书：KEMA 03 ATEX 2403 X

防护等级：II 2 G，Ex demb [ia] IIC T6
