CAMBRIDGE, UK — SenGenuity announces the TempTrackr, a wireless temperature measurement system kit with six sensor capability, aimed at continuous monitoring of OEM and industrial process control applications. ' TempTrackr is 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. This wireless temperature measurement system is highly scalable and can accommodate up to 12 wireless temperature sensors with appropriate setup and configuration.

The system provides a passive, wireless and electrically non-invasive temperature monitoring solution for switchgear, overhead transmission lines and other electrical transmission and distribution equipment used in smart grid applications, rotating equipment and wireless food probes.

In contrast to traditional methods, such as infrared thermography, the kit provides a highly cost effective continuous temperature monitoring capability that requires little to no long term maintenance.

By making use of passive sensors, the system also provides a logistical and environmental advantage over battery-powered sensors by doing away with the need for constant battery replacement.

The kit includes six wireless temperature sensors (each capable of reading temperatures from -40 to 220C) a USB powered wireless transceiver, antennae, connectors and PC based application software.
