EE046
Condensation Monitor
EE046 condensation monitor helps prevent condensation on
chilled beams and other critical cold spots and is appropriate
for mounting onto plane surfaces and on pipes with max.
50 mm (2”) diameter. It features the well-proven E+E HC105
SMD humidity sensor.
Condensation on a surface occurs when the relative humidity
(RH) of the air close to the surface reaches 100 % RH.
Because of very good thermal coupling with the surface,
EE046 measures directly the RH of the air at surface
temperature.

The relay output gives an early warning when approaching condensing conditions, before
condensation actually happens. It indicates also a power supply failure or a broken cable.
A status LED indicates normal operation, alarm or power supply failure.
The E+E proprietary coating protects the humidity sensor against dust and dirt.
