Arrangement of a sensor in a holding device having a double ring seal, sensor, and method for mounting a sensor
An arrangement of a sensor in a holding device, the holding device having a passage opening and the sensor having a process connection at least partially inside the passage device, which achieves a reliable seal between the sensor and the holding device, wherein the holding device has an internal taper in a sub-region of the passage opening and the process connection has an external taper in a sub-region, which is constructed in a manner corresponding to the internal taper of the holding device and comes to bear against the same, wherein the external taper has a first section and a second section, wherein the first section and the second section are constructed from different materials.
1 . An arrangement of a sensor in a holding device, the holding device having a passage opening and the sensor having a process connection, which is arranged at least partially inside the passage opening, wherein the holding device has an internal taper in a sub-region of the passage opening and the process connection has an external taper in a sub-region, which is constructed in a manner corresponding to the internal taper of the holding device and comes to bear against the same, wherein the external taper has a first section and a second section, wherein the first section and the second section are constructed from different materials and wherein the first section and the second section of the external taper each directly bear against the internal taper of the passage opening.
2 . The arrangement according to claim 1 , wherein the first section is constructed from a dielectric material.
3 . The arrangement according to claim 1 , wherein the first section of the external taper is part of a lens for emitting a coupled HF signal.
4 . The arrangement according to claim 1 , wherein the second section is constructed from metal.
5 . The arrangement according to claim 4 , wherein the metal is provided with an abrasion coating on the outside.
6 . The arrangement according to claim 1 , wherein the second section is formed by a housing of the sensor.
7 . The arrangement according to claim 1 , wherein the external taper has a smaller angle in relation to the axial direction than the internal taper.
8 . The arrangement according to claim 1 , wherein the sensor and correspondingly the holding device form a stop, which delimits the maximum insertion depth of the sensor into the holding device.
9 . A method for mounting the sensor of claim 1 in a holding device having a passage opening, wherein when inserting the sensor into the holding device, an internal taper of the holding device and an external taper of the sensor are arranged such that they directly bear against one another and a first section and a second section of the external taper of the process connection are directly pressed against the internal taper of the passage opening and thus a double annular seal is created.
10 . The method according to claim 9 , wherein a maximum insertion depth of the sensor into the holding device is defined by a stop and/or a maximum screw-in force.
