The condensate that accumulates comes out via the condensate nozzle on the
heat exchanger 5 (see Fig. 8).
The condensate is removed automatically by the peristaltic pump, which is
incorporated as an optional extra.
The measuring gas outlet temperature is measured using the Pt-100 temperature
sensor in the cooling block 7 of the sample gas cooler, and displayed in digital
form in °C on temperature controller 9 (see Fig. 8). The sample gas outlet tempera-
ture is set in the factory to +3 °C.
The temperature controller sends out a status signal if the temperature rises
above / falls below the respective limit values of +3 °C ± 3 °C as set up in the
factory. This signal is present at a floating change-over contact that is rated up to
250 V AC / 2 A.
The set point for the sample gas outlet temperature can be set at the temperature
controller:
Press key P; the set point is displayed. Use arrow keys to adjust the set point.
Press key P; the new set point is stored.
