Non-contacting sensors

Abstract

A system and method for measuring the deflection angle of a cable from an initial position is disclosed. The cable is energized with an alternating electric current that creates a magnetic field associated with the cable. Pickup coils are positioned adjacent to the cable and oriented to measure the deflection of the cable in different directions. In an initial position, the magnetic field of the cable is parallel with and does not interact with pickup coils. In the deflected position, the magnetic field of the cable intersects and interacts with the pickup coils. The interaction of the magnetic field with the pickup coils induces a voltage in the pickup coils that indicates the angle of deflection of the cable. Also disclosed are methods and devices for providing a more durable and rugged sensor capable of detecting forces along a single axis. Still other embodiments disclose methods and devices for determining the orientation of a surface or object with respect to another surface.
