System overview
A complete Rosemount CT5800 system consists of a gas handling system, the analyzer,
and the associated interconnecting wiring and gas piping.
Measurement data from the analyzer can be displayed in the process control center.
The Rosemount CT5800 is supplied by Emerson. The gas handling system may be provided
by either you or Emerson, depending upon the specific installation. The circuit breakers
used to control the application of electrical power to the analyzer, the interconnecting
wires, and gas piping are provided by you. In
colored blue, customer-supplied items are colored purple, and items that can be supplied
by either Emerson or you are green.

The analyzer is designed for industrial process applications requiring ATEX Zone 1
hazardous area certification and uses an Ex d flameproof enclosure. It contains an optical
system with multiple lasers and a series of optical components that provide an optical
path, a heated multi-pass analysis cell, and sample and outlet ports that can be connected
to a gas handling system, and control and analysis electronics. The number of lasers
installed depends upon customer requirements. The complete system operates Vac from
a 110/240 Vac 50/60 Hz supply.
Gas concentrations are measured using mid-infrared optical absorption spectroscopy. The
light sources are lasers, which are operated to produce wavelength sweeps that cover the
absorption lines of the gases. The light from each laser is routed through an optical path to
the analysis cell, which provides measurement of low concentrations of the subject gases.
An external sample handling system conditions the sample gas and draws it through the
analysis cell. The light exits the multi-pass analysis cell and is directed to a receiver in the
