Abstract: In an inductive sensor a ferrous core is provided and has generally opposed first and second ends. A winding assembly surrounds the core. First and second magnets are coupled to the first and second ends of the core and are oriented relative to one another so that like magnetic poles are opposing one another along a length defined by the core.

Abstract: An orientation sensor includes a sensor body. At least four magnetic sensors are coupled to the sensor body. The sensors are positioned in a non-planar arrangement, one relative to the other. A processor is in communication with the magnetic sensors. The processor is programmed to compute, based on signals generated by at least three of the sensors, the magnitude of a vector oriented in a direction substantially coincident with an inclination direction of a magnetic field in which the sensor is located.

Abstract: A performance measuring system for a rotating shaft comprises a first annular support assembly to be coupled adjacent to a first end of a rotating shaft inwardly of associated shaft bearings. A second annular support assembly is to be coupled adjacent to a second end of a rotating shaft inwardly of associated shaft bearings. A third annular support assembly is to be coupled to the rotating shaft between the first and second support assemblies. A laser source is mounted on the first annular support assembly. A laser detector is mounted on the second annular support assembly. First and second magnetic sensors for detecting the Earth's magnetic field are mounted respectively on the first and second annular support assemblies. An accelerometer is mounted on the third annular support assembly for generating a fourth detection signal.
