RLAnet
Benefits
- Quick and precise localisation of the leakage location
- Modbus RTU integration into the building surveillance
- Can be combined with the sensor cable or point sensor
- Monitoring lengths up to 500 m
- Up to 50 point sensors
- Available as factory pre-assembled wall box IP65
Description
The monitoring unit RLAnet operating with the sensor cable SCR and/or the point sensor PS as well as the optical point sensor PSO/PSO+. 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 signaling 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. The max. monitoring length is 500 m. Up to 50 point sensors can be installed.
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 can be handled. The typical application parametrization will also be managed by using this service-software.
