Abstract
An apparatus for detecting the pressure and temperature in the intake tube of an internal combustion engine. A temperature sensor and a pressure sensor are secured to a carrier together with an evaluation circuit in a common housing with as little strain as possible. The housing includes at least two chambers separate from one another, one of which forms a pressure chamber that communicates with the intake tube via a stub and is sealed off from the environment in which the pressure sensor is secured. The other chamber serves to secure the temperature sensor therein by use of connection elements, and sealing adhesive connections that decouple mechanical strains for securing the carrier and sealing off the pressure sensor.
