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 intera ct 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.
