    摘要： Systems and methods for measuring displacement parameters of rotating shafts and couplings are disclosed. In some aspects, a measurement system includes a shaft extended in a longitudinal direction and a target wheel configured to rotate with the shaft. The target wheel includes sensor targets circumferentially distributed around the target wheel. Some of the targets are slanted in the longitudinal direction and some of the targets are parallel to the longitudinal direction. The measurement system includes a sensor array including at least three sensors mounted radially around the shaft and configured to detect the sensor targets as the target wheel rotates with the shaft. The measurement system includes a controller configured to receive sensor signals from the sensors and determine, based on the sensor signals, at least an axial displacement measurement of the shaft in the longitudinal direction and a radial displacement measurement of the shaft.

    摘要： An example device includes an inner element, an outer surrounding element, and a plurality of connecting flexural elements coupled between the inner element and the outer surrounding element. The inner element has a plurality of reflective surface areas that are configured to reflect light to a sensor. The outer surrounding element surrounds the inner element. The plurality of connecting flexural elements allow the inner element to move relative to the outer surrounding element.

    摘要： In an embodiment, a relative deflection detector may include at least two structural arcs, and a predetermined number of means for measuring position capable of determining the relative deflection in a first component. The at least two structural arcs may be for example, comprised of a first and second structural arc whereby the first and second structural arcs are attached to the first component at respective first and second predetermined locations and whereby each arc is comprised of a respective sequence of indicators, such as, for example, codes inscribed on the outer circumference of each arc. The first and second structural arcs may be positioned in concentric and coplanar relationship with each other. The predetermined number of sensors may be comprised of a first and second optical encoder sensor each positioned in proximate and coplanar relationship with the first and second structural arcs so as to read the first sequence of codes, second sequence of codes, or both, and thereby detect positions of each structural arc (e.g., a first position corresponding to the first structural arc and a second position corresponding to the second structural arc). The first and second positions may be used to calculate and thereby determine a relative deflection of the first component.

    摘要： A method to determine a characteristic on a turbine shaft is provided. The method includes disposing a reflective/absorptive target comprising a plurality of markings in a geometric pattern on the component. A light emitting source will then be focused onto a predetermined starting position on the target. The plurality of markings will linearly traverse across the light emitting source from the predetermined starting position. The reflected/absorbed light pulses from the plurality of markings will be detected and recorded. From the timing of the recorded light pulses, the characteristic of the component is determined. The geometric pattern comprises at least two non-parallel lines and a third line including the predetermined position. A system to determine a characteristic on a turbine shaft as well as a method to determine the torsional deflection of a turbine shaft are also provided.
