Abstract
A pressure sensor includes a sensor housing that defines a chamber, a measuring element within the chamber, and a diaphragm that closes the chamber at a front end of the sensor housing. An accommodating body is spaced apart from the front end and configured to be inserted into a bore of a mounting body. The front end defines a sealing element configured at least locally conically on its outside for sealing the sensor housing in the bore.
Claims19
(canceled)
The pressure sensor according to claim 15, wherein the outer surface of the sensor housing defines a conical sensor housing portion that diverges away from the diaphragm in the direction of the accommodating body;
- and wherein the sealing element is arranged in the conical sensor housing portion.
The pressure sensor according to claim 15, wherein the sealing element is formed by a component separate from the sensor housing and connected to the sensor housing by a conically shaped form-fitting connection.
The pressure sensor according to claim 15, wherein the sensor housing is directly connected to the accommodating body.
The pressure sensor according to claim 15, wherein the sensor housing is connected to the accommodating body via an interposed, annular, heat compensation element, wherein the material of the sensor housing and the material of the accommodating body have different coefficients of thermal expansion.
The pressure sensor according to claim 15, wherein the accommodating body defines a tool engagement surface that connects the pressure sensor to the mounting body.
A pressure sensor arrangement comprising:
- a mounting body that defines a bore containing an interior space for housing a medium subject to pressure changes;
- a sensor housing defining a front side end and a back side end spaced apart along a longitudinal axis from the front side end, wherein the sensor housing defines a chamber that is hollow and disposed between the front side end and the back side end, wherein the front side end defines a diaphragm that closes the chamber at the front side end of the sensor housing;
- a measuring element disposed in the chamber of the sensor housing in operative connection with the diaphragm for detecting a pressure-dependent deformation of the diaphragm;
- an accommodating body connected to the back side end of the sensor housing and configured to be inserted into the bore of the mounting body and connected to the bore of the mounting body by means of a mounting portion defined on an external surface of the accommodating body:
- a sealing element configured for sealing the sensor housing in the bore of the mounting body, wherein the sealing element defines an external surface that is conical in shape, wherein the sealing element defines an internal surface that is connected to an outer surface of the sensor housing, wherein the outer surface of the sensor housing is disposed between the front side end and the back side end of the sensor housing.
(canceled)
A pressure sensor for disposition into a bore of a mounting body containing an interior space subject to pressure changes, the pressure sensor comprising:
- a sensor housing defining a front side end and a back side end spaced apart along a longitudinal axis from the front side end, wherein the sensor housing defines a chamber that is hollow and disposed between the front side end and the back side end, wherein the front side end defines a diaphragm that closes the chamber at the front side end of the sensor housing;
- a measuring element disposed in the chamber of the sensor housing in operative connection with the diaphragm for detecting a pressure-dependent deformation of the diaphragm;
- an accommodating body connected to the back side end of the sensor housing and configured to be inserted into the bore of the mounting body and connected to the bore of the mounting body by means of a mounting portion defined on an external surface of the accommodating body;
- and
- a sealing element configured for sealing the sensor housing in the bore of the mounting body, wherein the sealing element defines an external surface that is conical in shape, wherein the sealing element defines an internal surface that is connected to an outer surface of the sensor housing, wherein the outer surface of the sensor housing is disposed between the front side end and the back side end of the sensor housing.
