Circuit arrangement and method for controlling and evaluating signal detectors

摘要

A circuit arrangement ( 10 ) for activating a sensor and evaluating its signals, in particular for parametric sensors with complex impedances. The circuit arrangement comprises at least one sensor ( 2 ) for acquiring mechanical data. In order to minimize or largely prevent temperature caused disturbances in a constructionally simple layout, the measuring signal, the absolute temperature, and the gradient temperature of the sensor ( 2 ) are acquired simultaneously, preferably by means of a microprocessor or microcomputer ( 3 ). A corresponding method for activating sensors and evaluating their signals is also described.
