A LOW-COST INTERROGATION UNIT AND SIGNAL PROCESSING FOR A SAW IDENTIFICATION-TAG FOR A PRESSURE SENSOR
Andreas Stelzer, Robert Hauser, Leonhard Reindl, Rüdiger Teichmann
Abstract:
A solution for uniquely identifying any sensor connected to an evaluation unit without direct electrical connection to the existing measurement line is presented. The proposed solution is compatible with existing measurement systems, operates completely passive, and withstands temperatures up to 400°C as well as shocks up to 3500 g. The identification tag itself, which carries a unique serial number, is realized by a high-temperature stable surface acoustic wave (SAW) device. A low-cost radio frequency (RF) interrogation unit, which shares the existing sensor cable, is used for reading the sensor identification number.
