Operating instructions
The pressure dew point probe
Place the measuring chamber on the humidity probe
adapter and screw on tightly by hand.
The humidity probe can also be used without the PTFE
sintered cap, in which case the response times are
shorter. However, the probes can become dirty or
damaged during assembly or application.
If possible always use a sintered cap with the probe. A
metal protection cage (Order no. 0554.0755) can be
used with absolute oil-free compressed air.
Connect the probe to the instrument
In order to obtain a real measuring value, let
compressed air escape from the outlet for about 10
seconds.
Connect the humidity probe to the compressed air
plant. Compressed air flows out of the capillary wire
(shortening of the response times).
6
Make sure that the measuring chamber and
the valve are not dirty.
The reduction of pressure at the outlet leads to a
physical reduction in the pressure dew point value.
See the table in appendix B.

Valve to
control the
air flow rate
Using the valve you are able to control the air
flow rate which flows off to get an optimized
response time with the humidity sensor
