Abstract
An inductive sensor device for sensing the level of a liquid within a reservoir. The inductive sensor device includes a rotor pivotally connected to an overmold housing. Further, an inductive coupler is mounted to the rotor. Moreover, a float is connected to the rotor to pivot the inductive coupler by the at least one receiving coil to determine the level of liquid within the reservoir.
Claims19
A sensor device for sensing the level of a liquid on a reservoir comprising:
- a rotor pivotally connected to a housing;
- an inductive coupler mounted to the rotor;
- a float connected to the rotor to pivot the inductive coupler by the at least one receiving coil to generate a signal indicating the level of liquid in the reservoir.
A sensor for measuring a level of fluid, the sensor comprising:
- at least one printed circuit board containing at least one transmitting coil and at least one receiving coil;
- a rotor positioned adjacent to the single printed circuit board, the rotor having a coupler, the rotor connected to a float contained within the liquid, the coupler in communication with the single printed circuit board to measure angular displacement of the rotor in response to movement of the float.
A sensor for measuring a level of fluid, the sensor comprising:
- at least one single printed circuit board containing at least one transmitting coil and at least one receiving coil;
- a rotor positioned adjacent to the single printed circuit board, the rotor having a sensing coupler, the rotor connected to a float contained within the fluid, the coupler in communication with the single printed circuit board to measure angular displacement of the rotor in response to movement of the float;
- at least one transmitting coil providing an electric current, the transmitting coil produces an electromagnetic field when energized;
- the sensing coupler in the rotor is a resonator and generates an induced magnetic field which is received by at least one receiving coil;
- and
- at least one single printed circuit board that detects the changes in the magnetic field generated by the sensing coupler and determines a position of the rotor.
