Temperature-Monitoring
The monitoring unit displays the measured cooling temperature of the sample gas (black hand) as well as
the defined lower and upper limits (green and red hands).
NOTICE: Temperature display! A dew point within 0°C and +10°C displayed on the control
unit is correct according to the possible working conditions (gas flow-rate, gas inlet
temperature, gas inlet dew point, ambient temperature, etc.). If the dew point goes under 0°C
or over +10°C a malfunction is reported over the potential free alarm contact.
