AIR CONDITIONING TECHNOLOGY
DEW POINT SENSOR, TPS
TECHNICAL DATA
APPLICATION
Storage temperature:
−20 to +70 °C
These dew point sensor were developed in conjunction with alre dew point monitors and cooling ceiling controllers for the specific pur- pose of detecting and signalling the dew point. In this way, they prevent dripping condensa- tion water from reaching the cooling circuit parts, if installed correctly.
Sensor wire extendible up to:
50 m with 2 x 0.5 mm²
Connecting cable:
10 m
Accessories:
For use with dew point sensors (e.g., WFRRN) or climate control- lers with dew point monitoring (KTRRB, KTRRU, KTRRUu, KTRVB, KTFRL, KTFRD)

Important note: The inflow channels of TPS-1 and TPS-2 are closed at the factory to avoid dirtying during assembly. After assembly, they must be shortened with a knife until they are flush with the wall or ceiling to ensure air circulation. The air ducts should be arranged such that soiling during operation is avoided. It is important that the air surrounding the sensor has the same temperature as the room air to be cooled. If the humidity and temperature of the air to be cooled (ceiling cooling system) is different from that of the air surrounding the sensor, condensation may be detected prematurely or too late. As regards TPS-3, contact with the PCB paths must be avoided to prevent long-term corrosion. Attention in case of sensor extension: Parallel laying to conductors carrying a mains voltage can result in faults. The use of shielded conductors reduces sensitivity to electromagnetic fields.
Mode of operation – dew point sensor: if the surface temperature of the dew point sensor is equivalent to the dew point, a microscopic film of moisture forms on its surface. This film changes the resistance value of the dew point sensor to such an extent that the con- nected controller or monitor detects this change and disables the cooling. In this manner, dripping condensate water at maximum cooling, and hence mois- ture damage to the building, are avoided. When the dew point sensor dries off again, the resistance value increases and cooling is re-enabled. To ensure that a pending undershooting of the dew point is detected in time, 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. Generally, these locations are at the inlet coming into the room and / or near windows. If the place where the dew point is likely to occur cannot be unambiguously determined, it is possible to connect up to 5 dew point sensors in parallel to one controller or monitor.
