Disclosed is a measurement system magnetic coupler. The system comprises reader head apparatus for establishing a measurement related to the location of a physical structure moveable along a predetermined path. The system also includes a magnet for coupling the reader head apparatus to the physical structure by magnetic attraction between the magnet, the reader head apparatus, and the physical structure.

Measurement system magnetic coupler

Disclosed is a measurement system having multiple display orientations. The measurement system comprises a reader head having a reader element, and a display module. The reader element is configured for lateral movement with respect to a calibrated reference member for making a measurement relative to a reference position on the calibrated reference member. The display module is for displaying a measurement and includes coupling hardware for connecting the display module to the reader head so that the display module can be read horizontally independent of whether the reader head is oriented horizontally, vertically, or in some other direction.

Measurement system having multiple display orientations

Disclosed is a measurement system having reader element standoff. The system comprises a calibrated reference member for use with a reader head in making a measurement. The system also includes a reader head comprising a reader element configured to move laterally with respect to the calibrated reference member for making the measurement relative to a reference position on the calibrated reference member. Also, standoff structure is provided for establishing a variable standoff distance between the reader element and the calibrated reference member while substantially invariably maintaining a fixed lateral position of the reader element within the reader head.

Measurement system reader element standoff

Disclosed is a measurement system for providing a direct reading of a position on either side of a reference position. The system comprises a reader head including a reader element configured to move laterally with respect to a calibrated reference member for making a measurement relative to a reference position. The measurement system also includes mode display apparatus for increasing or decreasing the measurement which is displayed as the reader element moves away from or toward a selected side of the reference position.

Bi-directional direct read measurement system

Disclosed is a capacitive measurement system. The system comprises structure for generating a plurality of waveforms, a calibrated reference member for use with a reader head in making a measurement, and a reader element configured for lateral movement with respect to the calibrated reference member. The calibrated reference member comprises one element of a capacitor. The reader element comprises a plurality of reader regions comprising the other element of the capacitor. The reader element also includes structure for receiving two signals resulting from coupling of the two capacitor elements. The system functions to detect a phase shift level between the two signals and to determine magnitude of lateral movement in a particular direction from the magnitude of the phase shift.
