(SenGenuity: Hudson, NH) -- SenGenuity, the sensors division of Vectron International, announced that its TempTrackr Wireless Temperature Measurement System Kit is now capable of reading six independent, passive, wireless temperature sensors. Each sensor operates in a unique frequency band, which prevents cross talk with other sensors and provides them unique identification within the system architecture.

Based on surface acoustic wave (SAW) technology, the sensors require no batteries or external power supply. They are powered by electromagnetic bursts generated by a wireless transceiver, which serves to power the sensors and listen to response signals generated by them. A change in the frequency of the response signal is indicative of a change in the temperature being measured.
