WFRRN Electronic Dew Point Monitors
WFRRN range (Air Conditioning Technology)
For interrupting cooling when the relative atmospheric humidity exceeds approximately 98%.
If the surface temperature of the dew point sensor is equivalent to the dew point, a microscopic film of moisture forms on the surface. This film changes the resistance value of the dew point sensor to such an extent that the connected controller or monitor detects this change and disables the cooling. In this way dripping condensate water at maximum cooling and, therefore, moisture damage to the building, are avoided.
When the dew point sensor dries off again the resistance value increases and cooling is re-enabled.
For greatest effectiveness the dew point sensor should be assembled at the point where the dew point is most likely to be reached first along the cooling circuit. Usually this will be at the inlet coming into the room and/or near windows. If there is not one particular place where the dew point is most likely to occur it is possible to connect up to five dew point sensors in parallel to one controller or monitor.
