Abstract
A proximity transducer system including an eddy current effect proximity probe, a proximity electronics module coupled to the probe, a monitoring system and a two-wire, current interface connecting the proximity electronics module to the monitoring system is disclosed. The proximity transducer system is operative for measuring position and vibration of a component to be monitored. The current interface is made up of a pair of wires, e.g., a twisted pair, and is adapted for providing power to the electronics module and an electrical signal from the proximity electronics module that is representative of (e.g., proportional to) the length of the gap between the probe and the component being monitored. That signal has a DC component that represents a steady state distance and an AC component that represents active movement of the component, such as vibration.
