A digital eddy current proximity system including a digital impedance measuring device for digitally measuring the proximity probes impedance correlative to displacement motion and position of a metallic target object being monitored. The system further including a cable-length calibration method, an automatic material identification and calibration method, a material insensitive method, an inductive ratio method and advanced sensing characteristics.

Method for measuring a gap between a proximity probe and a conductive target material

Digital eddy current proximity system: apparatus and method

A method and apparatus for controlling temperature stability of an inductor by using a magnetically coupled metallic object is disclosed in which a metallic object is magnetically coupled to the inductor by a magnetic field emanating therefrom. In one embodiment, the apparatus is tailored for use in a proximity probe of a machine monitoring system and includes the metallic object magnetically coupled to a sensing coil for controlling a resistance versus temperature profile including compensating for a proximity effect resistance of the coil.

Method and apparatus for controlling the temperature stability of an inductor using a magnetically coupled metallic object

A transducer mounting apparatus (10) is disclosed which includes a two-piece mounting bracket (20) and a verification device (100). The two-piece mounting bracket (20) includes a precisely machined base plate (22) and sliding plate (60). At least one transducer (150) is mounted to the sliding plate (60) and the sliding plate (60) is slideably coupled to the base plate (22) for precisely mounting and slideably positioning at least the one transducer (150) adjacent a 'target' to be monitored thereby. The verification device (100) couples to the base plate (22) and is employed in a method for calibrating and verifying the operation of at least the one transducer (150) prior to at least the one transducer (150) being mechanically locked into position by rigidly securing the sliding plate (60) to the base plate (22).
