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
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.
