A processing system for clearance estimation in a rotating machine includes one or more sensors and one or more digital signal processors for calculating the estimated clearance. The processing system may include techniques for obtaining real-time clearance estimates and techniques for obtaining averaged clearance estimates. Aspects of the processing system may also include a method of switching between real-time clearance estimates and averaged clearance estimates depending on the operating conditions of the rotating machine. Other aspects of the processing system include the use of two digital signal processors: a first digital signal processor configured to receive signals from a clearance sensor and perform a first set of high speed processing tasks, and a second digital signal processor configured to receive signals from the first digital signal processor and perform a second set of lower speed processing tasks.

System and method for clearance estimation between two objects

A sensor system for measuring a clearance parameter between a stationary component and a rotating component of a rotating machine is provided. The system includes a clearance sensor to output a clearance measurement signal. A sensor memory is attached to the sensor for storing a first sensor information. A second sensor information is stored in a electronics interface memory. The first and the second sensor information are read and the clearance sensor is matched with a respective plurality of calibration data by an electronic interface based on the first and the second sensor information.
