The Surface Range Extender is designed to measure the temperature of a metal surface, and also get maximum radio range (it is a variant of the Pipe Range Extender).
Placing a sensor flat on metal gives a very good measurement of the surface temperature, but as metal absorbs a lot of the RF energy, the radio range is severely degraded.
The surface range extender solves this by the use of a range extender embedded in a sensor accessory. The sensor is placed flat on metal, with the range extender lifted up from the metal surface. This design allows the radio waves to propagate better, hence achieving maximum range combined with great thermal coupling to the surface for accurate temperature measurements.
- Monitoring of motors and bearings, a temperature increase indicates maintenance needed
- Monitoring of high energy electric contacts (e.g. Smart Grid), temperature increase indicates overload or too high contact resistance. Maintenance needed to avoid breakdown.
- Monitoring of transformers, high temperature indicates an overload
- Monitoring of high energy fuses, high temperature indicates an overload
