Abstract
In accordance with an embodiment, a sensor arrangement includes a pressure transducer configured to be in fluid connection with a volume region having a fluid, where the pressure transducer is configured to output a pressure signal in response to a pressure change in the volume region, the pressure signal comprising a signal curve that depends on the pressure change; a heating element configured to provide a defined temperature change of the fluid situated in the volume region, wherein the defined temperature change of the fluid brings about a corresponding pressure change in the volume region; and a processing device configured to ascertain a current functional parameter of the pressure transducer based on the signal curve of the pressure signal obtained in the volume region due to the defined temperature change provided by the heating element.
