Abstract

A device for detecting the pressure and the temperature in the intake tube of an internal combustion engine, including a temperature sensor, a pressure sensor and a substrate each of which are secured in a housing with as little stress as possible with the pressure sensor secured on a substrate together with an evaluation circuit. The temperature sensor measures precise temperature measurement. In order to introduce a fluid medium that is under pressure, a neck part is secured to the housing and an adapter is joined both to the substrate and to the neck part via adhesive seals that decouple mechanical stress from the pressure and temperature detectors.
