Abstract: A position sensor monitors relatively fast moving objects with signal conditioning for reduced power and reduced wiring. A transducer and related circuitry generate a dynamic signal proportional to a position of a moving object and also generate one or more low frequency or static (DC or zero frequency) error signals. The low or zero frequency error signals are removed and a position signal is generated using only two connections to a remote sensor monitor, thus allowing ease in multiplexing and reduced wiring. Circuit options allow placing less circuitry on the sensor itself for small size or more circuitry on the sensor for less control requirement.

Abstract: A sensor monitoring system and associated methods are provide that preferably include a plurality of sensors connected in parallel across a single pair of wires that include resistances of equal value placed in series between each sensor. This allows each sensor to measure the voltage dropped between itself and the monitoring system to determine its relative placement on the bus to autonomously assign itself a number to delineate to the monitoring system its relative location on the equipment or item being monitored. The sensors modulate their internal resistance to change the current on the bus to transmit their status to the monitoring system.

Abstract: A proximity sensor is carried within a small diameter package and includes a magnet for providing a desirable magnetic field for operation of proximity sensing circuitry carried along a central axis to allow for a maximum sensor signal output with no change due to a relative rotation angle between the sensor and a target being monitored. Electrical contact pins include an offset positioned near the central axis for permitting a desirable small gauge insulated wire to be connected the sensor.
