Abstract

Eine SAW-Identifikationseinheit (3) für einen kapazitiven und/oder piezoelektrischen Sensor (1) mit zumindest einem Messwertaufnehmer umfasst ein eine Sensorkennung repräsentierendes SAW-Ele-ment (3a) und zumindest einen Anschluss (5, 10) für einen hochfrequenten Abfrageimpulse. Um für Sensoren mit beliebigem Aufbau und Eigenschaft das eigentliche Sensorsignal möglichst wenig zu beeinflussen und dennoch eine deutliche Identifikation zu gewährleisten, und diese mit wenig Aufwand einfach und sicher mit einer Abfrageeinheit zu koppeln, ist ein definierter Abschluss (3b) für Hochfrequenzimpulse auf der dem Anschluss (5, 10) für die Hochfrequenzimpulse abgewandten Seite des SAW-Elementes (3a) vorgesehen.A SAW identification unit (3) for a capacitive and / or piezoelectric sensor (1) with at least one transducer comprises a SAW element (3a) representing a sensor identifier and at least one connection (5, 10) for a high-frequency interrogation pulse. In order to influence the actual sensor signal for sensors of any structure and property as little as possible and yet to ensure a clear identification, and to couple these easily and safely with a query unit with little effort, is a defined conclusion (3b) for high-frequency pulses on the connection (5, 10) for the radio-frequency pulses facing away from the SAW element (3a).
