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.

The invention claimed is: 1. A sensor arrangement comprising: a sensor producing a sensor signal in response to a measurement parameter; and a signal processing means for the sensor signal, said signal processing means having a switching stage and a functional stage, said switching stage comparing the sensor signal with an output signal produced by the functional stage and producing a switching signal dependent on the comparison, wherein said functional stage includes a differential stage and a threshold value stage, said differential stage forming a first time derivative of the sensor signal, and said threshold value stage comparing said first time derivative of the sensor signal to a threshold value and generating said output signal depending on said comparison of the first time derivative of the sensor signal to the threshold value. 2. The sensor arrangement as set forth in claim 1, wherein the switching stage comprises a window comparator. 3. The sensor arrangement as set forth in claim 1, wherein the differential stage further forms a second time derivative of the sensor signal and wherein the output signal of the threshold value stage is used to form a turn-off or turn-on signal by the switching stage. 4. The sensor arrangement as set forth in claim 1, wherein the switching stage comprises an AND gate. 5. The sensor arrangement as set forth in claim 1, wherein the output signal of the threshold value stage is used to produce a turn-on signal by the switching stage when a value of the first time derivative is below the threshold value. 6. The sensor arrangement as set forth in claim 1, wherein the measurement parameter is in the form of a position or a movement or a pressure or a force or a flow rate. 7. A sensor arrangement comprising: a sensor producing a sensor signal in response to a measurement parameter; and a signal processing means for the sensor signal, said signal processing means having a switching stage and a functional stage, said switching stage comparing the sensor signal with an output signal produced by the functional stage and producing a switching signal dependent on the comparison, wherein said functional stage comprises a differential stage and a function part stage, said differential stage forming a first time derivative (s′) of the sensor signal and said function part stage forming the function s0−k×s′, and generating the output signal of the functional stage based on said function, s0 being a predetermined measurement parameter limit switching value and k being a predetermined factor. 8. The sensor arrangement as set forth in claim 7, wherein the switching stage comprises a window comparator. 9. The sensor arrangement as set forth in claim 7, wherein the switching stage comprises an AND gate. 10. The sensor arrangement as set forth in claim 7, wherein the measurement parameter is in the form of a position or a movement or a pressure or a force or a flow rate. 11. A sensor arrangement comprising: a sensor producing a sensor signal in response to a measurement parameter; and a signal processing means for the sensor signal, said signal processing means having a switching stage and a functional stage, said switching stage comparing the sensor signal with an output signal produced by the functional stage and producing a switching signal dependent on the comparison, wherein the functional stage includes a memory stage for storing the sensor signal at a predetermined point in time and an addition stage for adding the sensor signal stored in the memory stage to an offset value, the addition stage generating the output signal of the functional stage based on said addition. 12. The sensor arrangement as set forth in claim 11, wherein said predetermined point in time for storing said sensor signal in said memory stage is determined by a trigger signal received by said memory stage upon detection of a predetermined measurement parameter being reached. 13. The sensor arrangement as set forth in claim 11, wherein the switching stage comprises a window comparator. 14. The sensor arrangement as set forth in claim 11, wherein the switching stage comprises an AND gate. 15. The sensor arrangement as set forth in claim 11 wherein the measurement parameter is in the form of a position or a movement or a pressure or a force or a flow rate.
