Now sensor response
can be verified every
24 hours automatically.
Combustible Gas Detectors are used
in a wide variety of industrial plants
to detect gas leakage or buildup
before it reaches explosive levels.
These detectors rely on thermal
oxidation of any combustible gas or
vapor on the surface of a heated
catalyst. In other words, they simply
burn the gas and measure the heat
released in the combustion process.
While this type of sensor is generally stable and
reliable, it is also subject to poisoning by silicon vapor,
lead compounds, and other environmental contaminants.
To detect loss of sensitivity, most users test
combustible sensors either weekly or biweekly to
ensure response. The procedure is simple, but requires
manpower to perform the test.
ATI’s Auto-Test Combustible Gas Transmitter
eliminates the need for frequent response checks. This
transmitter performs an automatic gas test on the
sensing element every 24 hours. The result is a
combustible gas detector system with a level of
reliability beyond that of any other system available.
This daily sensor response verification is as close to a
fail-safe detection system as you can find, with the
added benefit of greatly reduced manual testing.
