Abstract
A location sensing assembly for sensing lateral motion of a conductive targetin an electromagnetic structure that actuates the conductive target. The location sensing assembly is shown having two embodiments. In a first embodiment, the sensing of the lateral movement of the conductive target is done using an inductive sensor. In a second embodiment, the sensing is done using a magnetic sensor. In both instances, the sensors are located in an enclosed environment with large magnetic fields passing therethrough.
Claims12
A location sensing assembly for sensing lateral motion of a conductive targetin an electromagnetic structure creating actuation of the conductive target, said location sensing assembly comprising:
- a signal generating circuit to produce an AC wave signal to create an AC electromagnetic field;
- an induced receiving circuit to receive the at least one modified AC electromagnetic field to induce a modified current;
- a signal receiver electrically connected to said induced receiving circuit to receive the modified current;
- and
- a signal analyzer electrically connected to said signal receiver to analyze the modified current to determine a linear location of the conductive target moving laterally within a structural frame securing the conductive target therewithin.
A location sensing assembly for sensing lateral position of a conductive target relative to an electromagnetic structure having a coil of conductive wire wound therein defining an inner coil diameter, a first side, and a second side, said location sensing assembly comprising:
- a first Hall Effect sensor disposed adjacent the first side of the coil for generating a first signal;
- and
- a second Hall Effect sensor disposed adjacent the second side of the coil for generating a second signal;
- and
- a control electrically connected to said first and second Hall Effect sensors to receive the first and second signals to compare them to identify the lateral position of the conductive target, such that each of said first and second Hall Effect sensors sense a change in the magnetic field when the conductive target moves with respect thereto.
