RDW 03

Monitoring Electronics without Locating
  • Rapid detection of leaks
  • Monitoring lengths up to 1000 m
  • Up to 50 point sensors
  • No system calibration required
  • Simple integration into the building surveillance
  • Can be combined with sensor cable and point sensor


The system detects even small liquid leaks quickly and reliably.
There is an optical and acoustic alarm signal.
At the same time potential-free contacts are set for signals to the building services management and control tasks.
The max. monitoring length is 1000 m. Up to 50 point sensors can be installed.
