1.2.2 NDIR Module and UA1372 Module (Optional) Measuring System
This block is the heart of the monitor. It contains the Infrared source
the sample cell and the Detector with specialized optical filters and
processing electronics necessary to do highly accurate measurement
of gas concentrations.
The UA1372 are connected to the NDIR module for data transfer to
the Controlling PC Software.
Measurement samples are sucked into the measurement chambers
via the Gas Inlet or the Zero Gas Inlet, depending upon the
command from the BZ6014. The internal gas-circuits (see figure 1.1 )
are arranged such that samples pass through the measurement
chamber in a continuous flow and directed from the NDIR sample cell
to the UA1372 Module to the Electrochemical Sensors. Exhaust gases
are expelled via the gas outlet. The Zero Gas used for zero
calibration of the NDIR Module and for Span Calibrating the Oxygen
Sensor is drawn via the Zero Gas inlet.
