Pressure sensor for detecting the pressure of the medium

Abstract

The invention relates to a pressure sensor, in particular for a brake device, in particular to a pressure sensor for detecting the pressure of a medium, comprising a connection flange (3) with a fluid channel (33) for connection to the medium to be measured ), the pressure measuring unit (2) arranged at the end of the fluid channel (33), and the line carrier (4), wherein the pressure measuring unit (2) has a contact surface (20) for contacting, The contact surface is arranged at an angle (α) to the central axis (X-X) of the pressure sensor.

Description

technical field

[0001] The invention relates to a pressure sensor for detecting pressure, in particular in a braking system of a vehicle. Background technique

[0002] Differently designed pressure sensors are known from the prior art. Known pressure sensors are used, for example, in brake systems of vehicles in order to detect the pressure of the brake fluid. Here, DE 10 2007 031 980 A1 discloses a pressure sensor having a centrally arranged pressure measuring cell. Furthermore, a carrier element and a printed circuit board fastened to the carrier element are provided. In principle, such a pressure sensor has already proven to perform well, but further miniaturization of the pressure sensor is necessary in addition to cost-effective production for future brakes. Especially in high-priced vehicles, a plurality of pressure sensors will be used in the future, so the pressure sensors must have as little installation space as possible. Contents of the invention

Embodiment Construction

[0025] next reference Figures 1 to 7 A pressure sensor 1 according to a preferred embodiment of the invention will be described in detail.

[0026] Depend on figure 1 It can be seen that the pressure sensor 1 includes a pressure measurement unit 2 and a connecting flange 3 . The connecting flange 3 has a port 31 , in which a fluid channel 33 runs, via which the medium whose pressure is to be measured is fed. The fluid channel 33 has an angled fluid channel section 34 . A receptacle 32 for accommodating the pressure-measuring cell 2 is provided at the end of the bent fluid channel section 34 . The connecting flange 3 is connected to a hydraulic system (not shown) via a port 31 .

[0027] Furthermore, the pressure sensor 1 comprises a circuit carrier 4 on which a plurality of electronic components 5 are arranged. pressure measuring cell 2 especially as figure 2 It is shown hexagonally shaped and has a contact surface 20 on which a plurality of contacts 22 are designed. ...
