Beschreibung
Zusammenfassung:	A sensor arrangement comprises a first sensor element for converting a physical quantity into a first electrical signal and at least a second sensor element for converting said physical quantity into a second electrical signal. The first sensor element has a first sensitivity while said second sensor element has a second sensitivity different from said first sensitivity. The first sensor element is operatively coupled between terminals of said sensor arrangement and said second sensor element is operatively connected between said terminals of said sensor arrangement via a temperature controlled switching element so that in a first state of said temperature controlled switching element, said second electrical signal combines with said first electrical signal to form a sensor output signal, and in a second state of said temperature controlled switching element, the contribution of said second electrical signal to said sensor output signal is substantially reduced with respect to a respective contribution in sai
