Abstract

A pressure measuring device includes a pressure sensor element and an analog-digital converter. An output signal voltage of the pressure sensor element is a function of a temperature and is applied as an input voltage to an input of the analog-digital converter. The analog-digital converter is adapted to convert any input voltage from input voltage ranges which vary with a temperature into a digital value representing the input voltage.
