16 Gas sampling and gas conditioning technology 14.1a-ME
The current cooler temperature is displayed on the multi-functional control unit TCU mounted on the
front panel. The setpoint temperature of the cooler can be set by pressing keys. In the event of
warnings or faults, plain text information appears on the display and is also indicated by LEDs (e.g.
cooler within the setpoint range and no other alarms - green LED, flow alarm (option) - yellow LED,
temperature ± 3° C from the setpoint and humidity alarm (option) - red LED).
The fine filter downstream of the cooler (different filter types available) provides for the necessary
separation of solids. The condition of the filter can be judged from the outside. To protect the
downstream analysers against liquid penetration and to increase the operating reliability of the whole
system, according to the selected filter type, a suitable liquid alarm is possible or already integrated
into the filter.
A group alarm or on request individual alarms including mA output for the cooler temperature at the
output terminals is available wired. Via potential-free contacts for the group alarm or the individual
alarms (cooler temperature, flow, fluid in the system), an alarm message and shutdown of the sample
gas pump, if present, occurs.
Integrated sample gas pumps are available in three performance levels to choose from N3/5/9 KPE.
The flow meter FM40 arranged in the sample gas outlet with a measuring range adapted to the pump
power can be supplied for flow monitoring with a flow sensor FA-20mo. In addition, each sample gas
line can be equipped with a second sample gas outlet or bypass flow meter and flow control.
In the event of an aerosol problem, a liquid particulate filter CLF can be added downstream of the flow
meter in the sample gas outlet.
Via expansion modules for the control unit TCU two further temperature controllers are available e.g.
to regulate heated lines or gas probes. Here too external sample gas pumps can be connected and
individual sample gas probes can be backflushed.
