Über Sontex Radio
Sontex Funk (Radian) ist ein Funkprotokoll für die Gebäude- und Energietechnik. Es ermöglicht den drahtlosen bidirektionalen Datenaustausch zwischen Geräten wie Heizkostenverteilern, Wärme- und Wasserzählern sowie zentralen Erfassungssystemen.
Standard & Anwendungen
Sontex Funk (Radian) ist ein Funkprotokoll für die drahtlose Übertragung von Verbrauchs- und Messdaten in der Gebäude- und Energietechnik. Es wird vor allem für Heizkostenverteiler, Wärme- und Wasserzähler eingesetzt und ermöglicht die automatische Auslesung von Zählerdaten über Funk.
Durch die bidirektionale Kommunikation können Daten nicht nur übertragen, sondern Geräte auch aus der Ferne verwaltet werden. Die Technologie ist speziell auf Automatic Meter Readout-Anwendungen ausgelegt und wird häufig in Systemen von Sontex eingesetzt.
Technical performance
Being based on wired communication, its main advantage is the reliability. Unlike radio solutions that always are exposed to changing environments, being affected by other devices that uses the same spectrum and must penetrate changing physical environment, wired solutions are unaffected as long as the wire remains intact.
Bandwidth is limited but systems have excellent robustness against electrical disturbances, caused by e.g. lightning strikes, while at the same time allowing cable lengths up to several km using a standard 2 wire cable.
End devices, such as meters, are called slaves in M-Bus terminology. They are powered by an M-Bus master, typically a separate product or built into a more advanced gateway product. While this design allows meters to only need to rely on the M-Bus cable for both communication and power, it makes the collecting device unsuitable for battery power.
Both Wired and Wireless M-Bus supports
Two-way communication, but systems are, for technical reasons, most often thought of as “one way”, from the meter/sensor to a receiving system.
Encrypted meter/sensor data
Suitable applications
Wired M-Bus is still a very good and robust solution for applications using simpler meters/sensors and where the cost of cabling is acceptable. The latter is often a critical point making it more popular for e.g. new buildings rather than retrofit projects.
Sontex compatible M-Bus products
Sontex provides a wide range of devices to build complete M-Bus infrastructures, including meters, sensors, converters, gateways, and M-Bus masters. Their high-quality meters collect accurate data on heat, water, and electricity, while affordable sensors add valuable information to the network.
M-Bus gateways gather data from all meters and link it to Meter Data Management (MDM) software. These systems can be managed through both wired and wireless networks. M-Bus masters extend infrastructure capabilities, such as increasing cabling length or connecting more devices.
Sontex also offers pre-wired turnkey M-Bus solutions and accessories like splitters and adapters for easy installation and enhanced functionality.
