Abstract
A proximity sensor system can include a target assembly having one or more first targets comprising a first material having first magnetic permeability and one or more second targets comprising a second material having a second magnetic permeability. The system can include an inductive proximity sensor positioned relative to the target assembly to sense an inductance of the target assembly. The inductive proximity sensor and/or the target assembly are configured to move relative to the other.
Claims20
A proximity sensor system comprising:
- a target assembly, comprising:
- a target axis;
- one or more first targets comprising a first material having first magnetic permeability on the target axis;
- and
- one or more second targets comprising a second material having a second magnetic permeability on the target axis, wherein the one or more second targets are spaced from the one or more first targets on the target axis;
- and
- an inductive proximity sensor positioned relative to the target assembly to sense an inductance of the target assembly, wherein the target assembly is linearly shaped and the inductive proximity sensor moves linearly along the target axis of the target assembly for determining position of the inductive proximity sensor along the target axis.
A slat skew system, comprising:
- a proximity sensor system comprising:
- a target assembly, comprising:
- a target axis;
- one or more first targets comprising a first material having first magnetic permeability on the target axis;
- and
- one or more second targets comprising a second material having a second magnetic permeability on the target axis;
- and
- an inductive proximity sensor positioned relative to the target assembly to sense an inductance of the target assembly, wherein the target assembly is linearly shaped, and wherein the target assembly is attached to a slat, and wherein the inductive proximity sensor is mounted to a wing structure, and wherein the inductive proximity sensor moves linearly along the target axis of the target assembly having at least two targets spaced apart along the target axis for determining position of the inductive proximity sensor along the target axis.
A method, comprising:
- moving an inductive proximity sensor linearly along a target axis of a target assembly that is linearly shaped and having a first target made of a first material on the target axis and a second target made of a second material on the target axis;
- and
- determining if the inductive proximity sensor is disposed in proximity to the first target made of the first material or the second target made of the second material of the target assembly.
