Abstract
A multi-stage irreversible sensor coupling is provided. A sensor body includes a sensor and has a sensor body wall and at least one sensor body engagement feature. A clip barrel is configured to slidably engage the sensor body and has at least one clip barrel engagement feature. A wedge clip is configured to slidably engage the clip barrel and has at least one wedge clip engagement feature that is configured to urge the at least one sensor body engagement feature into cooperative engagement with the at least one clip barrel engagement feature when the wedge clip, clip barrel, and sensor body are fully engaged together.
Claims20
A multi-stage irreversible sensor coupling comprising:
- a sensor body having a sensor, the sensor body having a sensor body wall and at least one sensor body engagement feature;
- a clip barrel configured to slidably engage the sensor body, the clip barrel having at least one clip barrel engagement feature;
- and
- a wedge clip configured to slidably engage the clip barrel, the wedge clip having at least one wedge clip engagement feature that is configured to urge the at least one sensor body engagement feature into cooperative engagement with the at least one clip barrel engagement feature when the wedge clip, clip barrel, and sensor body are fully engaged together.
A process variable measurement system comprising:
- a sensor disposed within a sensor body;
- a controller disposed within an electronics housing;
- measurement circuitry electrically coupled to the sensor, the measurement circuitry being disposed within the electronics housing and coupled to the controller, the measurement circuitry being configured to measure an electrical characteristic of the sensor and provide a digital indication of the electrical characteristic to the controller;
- and
- wherein the electronics housing and the sensor body are coupled together via a multi-stage irreversible coupling.
A method of manufacturing a sensor coupling, the method comprising:
- providing a sensor body having a sensor;
- providing a clip barrel;
- providing a wedge clip;
- moving the clip barrel axially with respect to the sensor body until a collar of the clip body contacts an end of the sensor body;
- and
- moving the wedge clip axially with respect to the clip barrel until a wedge clip interference feature engages an internal wedge portion of the clip barrel.
