Abstract
Embodiments described herein are directed to a sensing system. The sensing system includes a pair of sensors, a target, and a pair of magnets. The target is configured to move along an axis of movement with respect to the pair of sensors. The pair of magnets are coupled to the target. Each of the pair of magnets has a first end and a second end. Each of the second ends of the pair of magnets are positioned axially adjacent to one another in a system longitudinal direction. The pair of magnets provide a greater field strength for determining a position of the target.
Claims19
A sensing system comprising:
- a pair of sensors;
- a target moves along a linear axis of movement with respect to the pair of sensors;
- and
- a pair of magnets coupled to the target, each of the pair of magnets having a first end and a second end and each end having an opposite polarity, each of the second ends of the pair of magnets are positioned axially adjacent to one another in a system longitudinal direction,
- wherein the pair of magnets provide a symmetrical field strength in a system vertical direction from a nadir positioned between the pair of magnets for determining a position of the target.
A Hall effect sensor assembly comprising:
- a processor unit,
- a pair of Hall effect sensors spaced apart defining a gap, the pair of Hall effect sensors communicatively coupled to the processor unit;
- a target moves along a linear axis of movement with respect to the pair of Hall effect sensors;
- and
- a pair of magnets coupled to the target, each of the pair of magnets having a first end and a second end and each end having an opposite polarity, each of the second ends of the pair of magnets are positioned axially adjacent to one another in a system longitudinal direction,
- wherein the pair of magnets provide a symmetrical field strength in a system vertical direction from a nadir positioned between the pair of magnets for determining a position of the target.
A sensing system that measures a position of a target, the system comprising:
- a pair of sensors;
- and
- a pair of magnets coupled to the target, each of the pair of magnets having a first end and a second end and each end having an opposite polarity, each of the second ends of the pair of magnets are positioned axially adjacent to one another in a system longitudinal direction,
- wherein the pair of magnets provide a symmetrical field strength in a system vertical direction from a nadir positioned between the pair of magnets for determining a position of the target when the target moves along an axis of movement with respect to the pair of sensors.
