摘要： A clearance sensing system for a rotating machine includes a plurality of sensor probes disposed within a stationary shroud of the rotating machine. Each of the plurality of sensor probes is adapted to measure a parameter indicative of an axial and a radial displacement of a rotating component within the shroud and to produce a signal that corresponds to the parameter. In certain embodiments, this parameter may include a capacitance between the rotating component and the sensor probe. The clearance sensing system further includes a circuit that receives the signal from each of the plurality of sensor probes and determines (a) the axial displacement of the rotating component within the shroud and (b) a radial displacement of the rotating component relative to the shroud.

摘要： A clearance measurement system is provided. The clearance measurement system includes a reference geometry disposed on a first object having an otherwise continuous surface geometry and a sensor disposed on a second object, wherein the sensor is configured to generate a first signal representative of a first sensed parameter from the first object and a second signal representative of a second sensed parameter from the reference geometry. The clearance measurement system also includes a processing unit configured to process the first and second signals to estimate a clearance between the first and second objects based upon a measurement difference between the first and second sensed parameters.

摘要： A technique for operating a sensor system is provided. The method includes exciting a first sensor with a first excitation signal at a first frequency and exciting a second sensor with a second excitation signal at a second frequency. The technique also includes combining a first measurement signal generated from the first sensor with a second measurement signal generated from the second sensor to determine a sensed parameter. The technique may be employed for reducing crosstalk between closely proximate sensors, such as capacitive probes, and may serve to determine distances within operating machines, such as turbine systems.
