Claims

[Claims for Utility Model Registration] (1) A housing, a sensor transducer in the housing, a support member that supports the sensor transducer, a pressure sensing element provided at one end of the housing, and a pressure sensing element provided at one end of the housing, and a connection between the sensing element and the transducer. a force transmitting member extending axially within the housing between the sensing element and the sensor transducer for effecting force transmission, the transducer being configured to output an output signal representative of the pressure applied to the sensing element. In response, the housing and the support member fit into each other such that the relative axial positions of the housing and the member are fixed by permanent plastic deformation of the housing, such as at pressures greater than atmospheric pressure in the combustion chamber of an internal combustion engine. A high pressure sensor that detects 2. The high pressure sensor of claim 1, wherein the pressure sensing element comprises a diaphragm having an edge clamped by a folded annular shoulder of the housing. 3. A high-pressure sensor as claimed in claim 1, characterized in that it comprises a guide member of the force transmitting member, which is cup-shaped and has an edge fixed to a corresponding edge of the housing. 4. The high-pressure sensor of claim 1, wherein the support member is an insulator having an annular recess, and the permanent plastic deformation of the housing is located within the recess. (5) a metallic annular housing having a diaphragm at one end, an insulator carrying a transducer, a conductor connected to the transducer, and a push rod coupling motion of the diaphragm to the transducer to produce an electrical output; a sensor, the insulator being locked into a tubular housing and forming a connection device for external connection to the sensor conductor. (6) A sensor substantially as herein described with reference to and illustrated in the accompanying drawings.
