Abstract
A sensor device for detecting a physical measurement variable is proposed including a sensor module as well as an electronic circuit module, wherein each value of the measurement variable is determined by comparison of an electrical voltage signal generated in the sensor module with a reference voltage generated in the circuit module and each value is output as a digital or analog coded signal at an output. Such a sensor device should solve the technical problem of making information about the amplitude of an internal electrical voltage signal accessible at all times for evaluation of the current tolerance situation. This is achieved in that the amplitude of this electrical voltage signal is represented by the period of a delay between the activation of the supply voltage for the sensor device and the output of the first valid measurement value.
