INSTALLATION
Please note
: CS Instruments recommends the indirect installation with measuring
chamber
Advantage
: Easy mounting and dismounting of the probe without interruption of the line.
Quick response time due to quick coupling.
Optimum sensor protection.
Indirectly in the compressed air system
Connect probe with measuring chamber to the com-
pessed air pipe by means of a quick coupling. In case
of compressed air containing oil and dirt particles a pre
-filter should be installed in front of the measuring
chamber. Compressed air flows continuously (at 7 bar
approx. 1 l/min expanded) in the capillary pipe of the
measuring chamber. The reaction times for the humid-
ity reading are shorter than in case of a direct mount-
ing.
Directly in the compressed air system
Screw in probe with G 1/2" thread pressure-tight in the
center or at the top of the compressed air pipe. Take
care that measurement is effected close to the com-
pressed air flow. U-bend pipes or non-flowing com-
pressed air result in very slow reaction times for the
moisture reading.
Measurable gases:
In general, humidity can be measured in all non-corrosive gases. In case of measurements in-
corrosive gases please consult CS Instruments GmbH.
