Tool for use during calibration of a sensor
A tool for use in connection with calibration of a load sensor, the tool comprising a first part comprising a first engagement member having a first contact surface to contact a lever of a load sensor, the lever being moveably mounted to a structure; and a second part comprising a second engagement member having a second contact surface to engage the structure, the second part being irremovable from the first part; wherein the second part is moveable relative to the first part along an axis between at least two selectively lockable predefined axial positions, each predefined axial position providing a predefined axial distance between the first contact surface and the second contact surface.
1. A tool for use in connection with calibration of a load sensor, the tool comprising:
a first part comprising a first engagement member having a first contact surface to contact a lever of a load sensor, the lever being moveably mounted to a structure; and
a second part comprising a second engagement member having a second contact surface to engage the structure, the second part being irremovable from the first part;
wherein the second part is moveable relative to the first part along an axis between at least two selectively lockable predefined axial positions, each predefined axial position providing a predefined axial distance between the first contact surface and the second contact surface.
2. The tool of claim 1 , wherein the first and the second parts are selectively lockable relative to one another in the at least two predefined axial positions by rotation of the second part relative to the first part around the axis to an interlocking position in which axial movement of the second part relative to the first part is prevented.
3. The tool of claim 1 , wherein the first and the second parts are selectively moveable between the predefined axial positions by rotation of the second part relative to the first part around the axis to a moveable position in which axial movement of the second part relative to the first part is allowed.
4. The tool of claim 1 , wherein the at least two predefined axial positions are defined by at least one protrusion formed on one of the first and the second parts, and at least two axially separated circumferential grooves formed in the other one of the first and the second parts, wherein the at least one protrusion is configured to selectively engage the circumferential grooves.
5. The tool of claim 4 , wherein the at least two circumferential grooves are connected by at least one connecting groove, wherein the at least one protrusion is configured to selectively engage the at least one connecting groove to move the second part between the at least two predefined axial positions.
6. The tool of claim 4 , wherein the at least one protrusion comprises at least two protrusions distributed around a circumference of the first or the second parts, the at least two protrusions being configured for simultaneous engagement with the same circumferential groove.
7. The tool of claim 4 , wherein the at least one protrusion is formed on the second part, and wherein the circumferential grooves are formed in the first part.
8. The tool of claim 1 , wherein the first part comprises an axially extending channel in which the second part is moveably received and from which the second part extends.
9. The tool of claim 1 , wherein the first part comprises a handle.
10. The tool of claim 9 , wherein the handle comprises recesses providing a structured gripping surface.
11. The tool of claim 1 , wherein the first engagement member comprises a radially extending base and two axially extending arms extending from the base, the two axially extending arms and the radially extending base forming a U-shaped slot for receiving the lever of the load sensor, the radially extending base defining the first contact surface.
12. The tool of claim 1 , wherein the second part comprises a rod and a circumferential shoulder extending radially outward from the rod, the circumferential shoulder defining the second contact surface to abut the structure when an end portion of the rod is received in an opening defined in the structure.
13. The tool of claim 1 , wherein each one of the first and the second parts is formed by material layers, wherein the material layers are stacked onto one another along the axis.
14. The tool of claim 1 , wherein the first and the second parts are made of the same material.
15. The tool of claim 14 , wherein the material is a metal material.
16. The tool of claim 1 , wherein the tool is configured to hold a lever of the load sensor in a fixed position during the calibration of the load sensor.
