EE45 condensation monitors are used to monitor the forma-
tion 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 dew point monitor for
systems operating near the dewpoint.
Because of the temperature coupling between the condensa-
tion monitor and the environment, the relative humidity is a
measure for the dew point. The condensation monitor meas-
ures the relative humidity near the dew point 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...).
A special coating protects electronics and sensor against contamination.
The EE45 series can be mounted on pipes, ducts and walls.
