4.7.4 CO METERING AND REGULATION CIRCUIT
2
Short description:
The replaceable, connector-compatible, thermal conductivity detector (TCD with
auto-zero or infrared (IR) sensor) is integrated in the sensor block. CO
is μP-based .
CO gas input is metered by a solenoid. The gas flowrate is also restricted by a
2
capillary opening with a diameter of 0.7 mm, integrated in the valve block. Before
entering the unit, the gas passes through a sterile filter that can be accessed from
outside the unit for replacement.
