Rated 5.00 out of 5 based on 1 customer rating

The monitoring unit RLAnet is a component of the BARTEC Water leakage detection system. It is operating with the sensor cable SCR and/or the point sensor PS. The system detects minor liquid leakages fast and reliable.

Quick and precise localization of the leakage location
Modbus RTU integration into the building surveillance
Can be combined with sensor and point sensor

The monitoring unit RLAnet is a component of the BARTEC Water leakage detection system. It is operating with the sensor cable SCR and/or the point sensor PS. Further components of the BARTEC Water leakage detection system are the monitoring units RLW, RDW 03 and RDA 01, also the accessories. The system detects minor liquid leakages fast and reliable. An optical and acoustic signal arises. Simultaneously the potential-free contact switches. This can be used for signalling to PLC or to a building control unit. The leakage is being localized exact by 1 meter and get visualized on the 4-digit display. Thus a leakage will be found by a service person quick and true.

Visualization The service-software (for WINDOWS-PC) calls the system status via RS485 in real-time. The data is available in MODBUS RTU protocol. Up to 250 MODBUS addresses will be handled. The typical application parametrization will also be managed by using this service-software.
