DESCRIPTION AND SPECIFICATIONS
1-1 OVERVIEW
This manual describes the CAT 100 Continu-
ous Analyzer Transmitter.
The CAT 100 is a 1 or 2 channel Continuous
Gas Analyzer with FOUNDATION Fieldbus
communications. Its Class I, Zone I (IIB) + H
2
approved enclosure makes it suitable for in-
stallation in hazardous environments. The
field mountable housing design allows the
CAT 100 to be mounted close to the process
instead of in a remote shelter. This feature
greatly reduces installation and utility costs
while improving process efficiency.
The CAT 100 can continuously measure 1 or
2 components in a single analyzer using a
combination of Non Dispersive Infrared
(NDIR), Paramagnetic Oxygen, Thermal Con-
ductivity, and Electrochemical sensors. The
CAT 100 also features an optional customized
sample-handling module.
1-2 TYPICAL APPLICATIONS
The CAT 100 Continuous Analyzer Transmit-
ter supports a variety of industry applications,
drawing on more than 40 years of develop-
ment and process expertise in sensors, digital
signal processing and software technologies.
The CAT 100 can satisfy the most demanding
single or multi-component analysis require-
ments. More than 60 gas components can be
measured including:
