Electrical connection
The electrical connection should be carried out by only expert person-
nel who are familiar with relevant safety regulations. Only a oating
voltage source (DC or AC) is needed as a supply. When many dew
point controllers are to be connected to the same voltage supply, all
the devices should be wired in the same manner to prevent earth in-
terconnection.
Assembly
For application as condensation monitor, the sensor must be installed
at the coldest location. A representation of the room atmosphere must
be available. Air ows or heat sources can disturb the functioning.
While assembling, it should be ensured that the sensor part is in direct
thermal contact with the tube or the object. Perfect functioning is gu-
aranteed only if there is no air-gap between the tube and aluminium
prole of the sensor. Therefore, a sensor is suitable only for a specic
cross section of the tube.
Improvised assembly leads to inevitable malfunctioning.
The mechanical tment is carried out through a cable strap provided
with the device or by mounting with screws. To improve thermal con-
duction, some thermal compound should be applied in the sensor area
between the aluminium prole and the tube. Only silicon free thermal
compounds should be used and only a thin coat should be applied!
It is recommended to check the functioning of condensation mo-
nitor after assembly at site in order to bring out any possible as-
sembly errors and prevent subsequent damages.
To check this, the cool ceilings must be undercooled below the dew
point level for a short period. During water condensate formation, the
dew formation monitor must respond and the static power circuit should
get tripped.
