METHOD OF MEASURING GAP BETWEEN MEASURING TRANSDUCER AND CONTROLLED SURFACE IN DYNAMIC MODES Russian patent published in 2008 - IPC G01B7/14 

FIELD: technological processes, measurement.

SUBSTANCE: invention is related to measurement equipment. Reference measurement is performed. The gap is measured at the value of not more than the reference. Additional measurement of gap is made, and values of measured gaps are corrected with consideration of reference and additional measurements results, and also value of gap reference measurement. At that results of reference and additional measurements of gap are determined as average values of subsequent measurements row with preset accuracy of approximation to limit value. Minimum value of gap reference measurement is found on the basis of inaccuracy of reference and additional measurements determination results, permissible accuracy of gaps measurements, inaccuracy of gap change by reference value, and also value of gap that is corrected.

EFFECT: reduction of gap measurements accuracy, reduction of manipulations number in the process of measurements and reduction of time spent for their performance.
