Wireless and Passive SAW Temperature Sensors

14 April 2012

SENSeOR launches a new version of its best-seller temperature sensor TSA F151 for wireless measurements with infinite autonomy.

Sophia-Antipolis, France – March 29th 2012 – SENSeOR announces the launch of sales of TSA F191, a new version of its best-seller temperature sensor TSA F151. Designed for wireless passive surface temperature measurement, the new TSA F191 is easily installed on any metallic part thanks to two magnets.

TSA F191 includes the same sensor chip as TSA F151 and is similarly mounted in a compact aluminum fixture. Based on a unique-patented differential structure, SENSeOR’s SAW sensors are the most stable devices on the market.

These sensors enable new measurements, at the most critical hot points of the monitored equipment, like inside turbines or generators, on the rotating bearings or on the rotor. Totally passive, they feature infinite autonomy, require no maintenance, and are free from any electrical risk. They can be easily installed inside electrical equipment like switchgears, or in any remote machinery, even in the most inaccessible places.
