The 201T series transmitters are able to detect a wide range of toxic and explosive gases. The 201T gas detection transmitter can work in an addressable network mode with the 301C controller through an RS-485 Modbus link. They can also be used

in a stand-alone conguration with

an optional 4-20mA or alarm relay outputs.

The catalytic sensors of the 201T can be used to detect hundreds of

different gasses and inammable

vapour concentrations. Toxic gasses are detected by way of electrochemical cells, while metal-air battery cells are used to detect oxygen. Moreover, a second generation of semi-conductor detectors offer a highly effective solution for a variety of different applications.
