Abstract

Apparatuses, systems, and associated methods of assembly are described that provide for improved probed assemblies for use in sensors configured to convert between motion and electrical signals. An example probe assembly includes a probe rod defining a first end. In an operational configuration, the probe rod is at least partially received by a sensor device. The probe assembly further includes a probe head that receives the first end of the probe rod. The probe head mates with the first end so as to secure the probe rod therein. The first end of the probe rod is further welded to the probe head via a butt welding technique.

First claim

The invention claimed is:

1. A probe assembly for use in sensors configured to convert between motion and electrical signals, the probe assembly comprising:
a probe rod defining a first end, wherein the probe rod is configured to, in an operational configuration, be at least partially received by a sensor device; and
a probe head configured to receive the first end of the probe rod, wherein the probe head is configured to mate with the first end so as to secure the probe rod therein,
wherein the first end of the probe rod is welded to the probe head via a butt weld in which the first end and the probe head are joined in the same plane.

2. The probe assembly according to claim 1 , wherein the first end of the probe rod further defines a first threaded element and the probe head further defines a second threaded element such that connection between the first threaded element and the second threaded element is configured to secure the probe rod within the probe head.

3. The probe assembly according to claim 1 , wherein the probe head defines an opening configured to at least partially receive the probe rod therein such that the first end of the probe rod is substantially aligned with an exterior surface of the probe head.

4. The probe assembly according to claim 1 , wherein the first end of the probe rod is substantially aligned with an exterior surface of the probe head.

5. The probe assembly according to claim 1 , wherein the probe rod further defines a second end opposite the first end, wherein the second end defines a third threaded element.

6. The probe assembly according to claim 1 , wherein the probe rod further defines one or more spacers disposed at least partially around the probe rod.

7. A sensor device for converting between motion and electrical signals, the sensor device comprising:
a bobbin tube, wherein the bobbin tube defines a hollow interior;
a probe assembly received by the bobbin tube, the probe assembly defining:
a probe rod defining a first end; and
a probe head configured to receive the first end of the probe rod, wherein the probe head is configured to mate with the first end so as to secure the probe rod therein, and wherein the first end of the probe rod is welded to the probe head via a butt weld in which

the first end and the probe head are joined in the same plane; and
one or more coil elements wound around the bobbin tube, wherein the one or more coil elements are configured to magnetically interact with the probe assembly.

8. The sensor device according to claim 7 , wherein the first end of the probe rod further defines a first threaded element and the probe head further defines a second threaded element such that connection between the first threaded element and the second threaded element is configured to secure the probe rod within the probe head.

9. The sensor device according to claim 7 , wherein the probe head defines an opening configured to at least partially receive the probe rod therein such that the first end of the probe rod is substantially aligned with an exterior surface of the probe head.

10. The sensor device according to claim 7 , wherein the first end of the probe rod is substantially aligned with an exterior surface of the probe head.

11. The sensor device according to claim 7 , wherein the probe rod further defines a second end opposite the first end, wherein the second end defines a third threaded element.

12. The sensor device according to claim 7 , wherein the probe rod further defines one or more spacers disposed at least partially around the probe rod.

13. A method of manufacturing a probe assembly, the method comprising:
providing a probe rod defining a first end, wherein the probe rod is configured to, in an operational configuration, be at least partially received by a sensor device;
providing a probe head configured to receive the first end of the probe rod;
mating the probe head with the first end so as to secure the probe rod within the probe head; and
welding the probe rod to the probe head wherein the first end of the probe rod is welded to the probe head via a butt weld in which the first end and the probe head are joined in the same plane.

14. The method according to claim 13 , wherein the first end of the probe rod further defines a first threaded element and the probe head further defines a second threaded element such that mating the probe head with the first end further comprises connecting the first threaded element and the second threaded element.

15. The method according to claim 13 , wherein the probe head defines an opening configured to at least partially receive the probe rod therein such that the first end of the probe rod is substantially aligned with an exterior surface of the probe head.

16. The method according to claim 13 , wherein the first end of the probe rod is substantially aligned with an exterior surface of the probe head.

17. The method according to claim 13 , wherein the probe rod further defines a second end opposite the first end, wherein the second end defines a third threaded element.
