Abstract

A sensor arrangement comprises a sensor responsive to a measurement parameter as a sensor signal and a signal processing means for the sensor signal, the signal processing means having a switching stage for comparison of the sensor signal with a comparison or switching value and for producing a switching signal in a manner dependent on the comparison. A functional stage is present, which constitutes one function of the sensor signal, is comprised in the signal processing means, such function including a time derivative of the sensor signal or a sensor signal value modified by an additive factor, and the output signal of the functional stage forming the comparison of switching value for the switching stage.
