The ‘TempTrackr’ multi-point wireless temperature measurement kit from Aspen Electronics is able to monitor the temperature of remotely located equipment and installations, or where power and communication to the sensor are restricted.
Developed by Vectron International’s SenGenuity division, and manufactured in Germany, the starter kit contains three passive wireless temperature sensors, capable of measuring temperatures between 0 and 120oC from a maximum interrogation distance of 1.78m.
The surface acoustic wave based sensors require no power source as they harvest energy from bursts of RF emitted by a wireless interrogator which excite resonators within each device.
The system can read multiple independent sensors in parallel, while the use of independent frequency bands (between 428 and 439MHz) ensure each can be individually identified.
