Embodiment approach

[0027] figure 1 A preferred embodiment of the device 10 according to the invention is shown therein, which is preferably fitted in a through hole 12 of a wall section 14. The device 10 also has a housing 16 which protrudes into the external environment 18 substantially in the region of the wall section 14 and penetrates the wall substantially only with a preferably rotationally symmetric pressure connector 20 through a through hole 12 provided for this purpose The section 14 extends into the chamber 22 for guiding the medium. The pressure connection 20 here preferably has a hollow cylindrical shape, so that the connection of the chamber 22 with the medium and the measuring chamber 24 arranged in the housing 16 is preferably established. The housing 16 of the device 10 is here preferably fixed to the wall section 14 by fixing elements not shown, in particular screws and / or bolts. In addition, the pressure connector 20 has an unnumbered groove on the outer peripheral surface of...

Abstract

The invention relates to an apparatus (10) for detecting the pressure and the temperature of a medium and to a method for producing such an apparatus (10). The described apparatus (10) has a temperature sensor (26) and a pressure sensor (28) arranged in a common housing (16), wherein the housing (16) also comprises at least one measurement space (24). The measurement space (24) is connected, via a pressure port (20), to a space (22) which accommodates the medium, wherein the pressure sensor (28) is arranged in the measurement space (24). The temperature sensor (26) also has connection lines (32). Corresponding connection contacts (38) are provided in the housing (16) for making contact with the connection lines (32) of the temperature sensor (26). At least one conical bushing (30) which opens into the pressure port (20) is also arranged in the housing (16) for the purpose of accommodating the temperature sensor (26), wherein the conical bushing (30) widens towards the pressure port (20). Provision is likewise made for a sealing compound (40) which surrounds the connection lines (32) of the temperature sensor (26) to be introduced into the conical bushing (30) at least in sections.

Description

Technical field [0001] This aspect relates to a device for sensing the pressure and temperature of a medium. Background technique [0002] Various sensors are known from the prior art for sensing at least one characteristic of a fluid medium in a measuring chamber. The fluid medium may be gas and / or liquid, for example. The at least one characteristic that can be sensed quantitatively or qualitatively may be any physical and / or chemical characteristic of the fluid medium or its flow. In particular, it is known to provide a sensor for sensing at least one temperature of the fluid medium. In the following, the present invention will be explained mainly with reference to a so-called combination sensor (pressure-temperature sensor) that can sense the pressure of the fluid medium in addition to the temperature. Such sensors are described, for example, in Konrad Reif's "Sensors in Motor Vehicles", first edition 2010, pages 134-135, FIGS. 3 and 4. In addition, such combined pressure...
