Abstract: Pressure and temperature inside a high-pressure container (common rail) are measured by means an ultrasonic emitter or an ultrasonic receiver which can detect the pressure inside the high-pressure container in a medium on the basis of the transit time of a pressure pulse. To this end, the ultrasonic receiver receives the pressure pulse, which propagates inside an additional element that is disposed between the ultrasonic emitter or ultrasonic receiver and the medium, and this propagation is ascertained accordingly in order to calculate a temperature from it.
