Promotion Leak KNX basic

Leakage Sensor for Water/Pipe Break Detection

The Leakage sensor Leak KNX basic for the KNX building bus system recognizes water, e.g. in case of a pipe breakage. If there is water between the electrodes of the probe, an alarm message will be sent to the KNX bus.


  • Detection of water on the probe
  • Alarm signal sent to the KNX bus with a text message
  • 4 AND and 4 OR logic gates with each 4 inputs. Every switching incident as well as 16 logic inputs in the form of communication objects, may be used as inputs for the logic gates. The output of each gate may optionally be configured as 1 bit or 2 x 8 bits
  • Configuration is made using the KNX software ETS 5
