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 BZ6013. The internal gas-circuits 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.
