1.3 Main Features of the Transmitter
The 2000 XTC Thermal Conductivity Transmitter is sophisticated
yet simple to use. It provides a 4-20 mA output signal proportional to
the concentration of one component of a gas mixture. The signal is
based on the difference between the thermal conductivity of the sampled
gas compared to calibration points. The main features of the analyzer
include:
Integral isolated safety barrier classified as intrinsically safe
for hazardous area use.
Nema 4X, IEC 60529 and IP 66 rated sensor housing
ATEX approved for EEx ib IIC T3 (Europe)
4-20 mA signal output proportional to the concentration of
one of the gases in the mixture.
Long-lifetime solid state thermal conductivity sensor
Temperature controlled cell block provides excellent zero
and span stability over a wide temperature range
Versatile analog signal processing IC.
Easy installation
1.4 Operator Interface
The user does not interact with the transmitter directly. The
standard 2000 XTC Thermal Conductivity Transmitter provides a 4-20
mA output signal proportional to the concentration of the gas being
analyzed. This signal can be used to drive devices such as displays,
concentration alarms, user-supplied devices, or it can be monitored
using a chart recorder.
