EE46 condensation monitors are used to monitor the formation of condensation on chilled ceilings and to prevent condensation at critical spots of heating-, ventilation- and air conditioning systems. It is also used as a dewpoint monitor for systems operating near the dewpoint.
Because of the temperature coupling between the condensation monitor and the environment, the relative humidity is a measure for the dew-point.

The condensation monitor measures the relative humidity near the dewpoint using its high-quality capacitive RH sensor. At reaching the switching point of 90% RH the output will provide an early warning signal for the initiation of control steps (increasing the initial water temperature, reducing the cooling capacity, switching on the heating, etc...).
