4 Installation
4.1 Installation Location
Select a location that offers optimum measuring conditions. Air must be able to circulate freely around
the sensing element.
Temperature differences between the process and the location of installation do not affect the dew point
measurement. However, attention should be paid to the fact that changes in the pressure of a gas also
changes the dew point. If there is a pressure difference between the location of installation and the
process, the measurement can be several tens of degrees dew point off.
The exact effects of changes in pressure on the dew point can be simulated using the E+E humidity
calculator. Please find further details on our website www.epluse.com.
Leakage should be avoided, as ingress of moisture from the environment will interfere with the
measurement.
Upon delivery the sensor is protected by a cap that keeps the dew point sensor dry. The cap
should only be removed right before installation into the application.
