The representation refers to the plug with the view of the contacts
as shown. The colors of cable depend on the batch and therefore
are not xed. Plug used: Westerplug 6-pole, 4-pole used (6P4)
Areas of application
• For cool ceilings to avoid condensation on tubes or cool panels.
• In the glass panels of indoor swimming halls or display windows
for keeping it frost free and ice free with optimum energy input.
• In water treatment plants or industrial installations for detecting
„sweating“ of cold pipeline network.
• To prevent condensate formation in the outside walls or steel
doors of halls and stockrooms and to protect the brick work.
• After any repair of cement ooring or at roofs, it is used to
detect any type of building leakage.
• For detecting condensate formation in the sensitive electronic
components of swithgear panels or machines.
• For moisture and leakage monitors: The potential free static
switch contact is compatible with all common commercial alarm
equipment and signalling systems.
Functional description
The condensation monitor is an electronic Hygrostat which is meant
to sense dew formation or beginning of water condensation on cooled
objects. As soon as the measured value of surface humidity
exceeds a certain limit (approx. 94 % RH), it opens the relay contact
and trips the static switch contact (safety function). For example, this
signal can be used for switching on a heater.
With the new measurement philosophy and application of a special
sensor with logarithmic characteristics, it is now possible to regulate
very close to the dew start point. With the help of this technology, now
the maximum cooling performance of the ceilings can be achieved,
without the risk of condensate formation.
During product development, reliable mode of operation was the most
important criterion. The circuit is protected against overvoltage, rever-
se polarity and faulty connections. In addition to the humidity sensing
element, which reacts to the critical air humidity values below the con-
densation limit, there is a safety circuit which detects the dew occu-
rence and independently trips the static power circuit. With the opti-
mised AC-circuit technology, the sensor experiences even a short time
contact with water without getting destroyed due to electrolysis effect.
A sinter lter over the sensor element protects it from accumulated dust
and ensures many years of operation without cleaning or maintenance.
The model with attached tubular sensor can be directly mounted on the
inlet of the cooling panels with minimum tment expenses.
