Honeywell VA201T Vulcain Gas Detection Transmitter

Vulcain Gas Detection Transmitter

The 201T gas detection transmitter is designed to meet or exceed safety requirements in a variety of commercial and industrial applications.

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 configuration 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 inflammable vapor 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 offers a highly effective solution for a variety of different applications.
