In order to evaluate the absolute humidity content (e.g. MRW) of air, it is therefore often
advantageous to measure the dew point in the compressed gas (at higher pressure).
Because of the measuring principle of the capacitive polymer sensors used here, exact
measured values can be achieved same as measurement in expanded air.
Physical conditions in compressed air are certainly more complex due to the large number of
effects and opposite acting factors. Therefore, the instrument is an important medium in
order to understand the processes and optimise the systems. Only in such a way, one can
ensure an everlasting constant quality of compressed air.
