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 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.

摘要： Self-calibration of a multiple channel clearance sensor system, which in one embodiment includes at least one sensor for measuring at least one clearance parameter signal between a stationary object and a rotating object of a rotating machine. The sensor output is processed as a clearance parameter by an offset correction section configured to determine an offset error in the clearance parameter signal which is used by a level shifter. The level shifter is also switchably coupled to the clearance parameter signal wherein the output of the level shifter, which may be amplified and digitally converted, is processed by a signal level analyzer to determine a channel gain signal.
