Condensation Monitor ANDKDW2 and ANDKDW2EXT or condensation sensors are typically mounted to cooling and cold water pipes (pipe mounted), cooling ceilings or other cooled surfaces.
Both models offer reliable detection of condensation and protect the objects against the former.
The ANDKDW2EXT has an external measuring point and can easily be mounted in confined spaces.
ANDKDWs can be used as monitors on cooling ceilings and pipes and the additional internal switching output is capable of activating heatings or other actuators.
