Condensation in Sample
System
Condensation will occur if the temperature of the
sample system or main pipe, at any point is below
(colder) than the DP temperature of the sample gas.
Once having formed, the sample reaching the sensor
will have a DP equal to the temperature of the
condensate, regardless of the DP at the sample point
