Title:
METHOD FOR THERMALLY COMPENSATING A GAGING DEVICE AND THERMALLY COMPENSATED GAGING STATION
Document Type and Number:
WIPO Patent Application WO/2010/004011
Kind Code:
A3
Abstract:
Thermal drifts compensation method in a gaging device (1) with a transducer; the compensation method includes the steps of : determining and storing, in the course of a calibration operation, values of a thermal compensation coefficient (K) upon variation of a temperature (T) of the gaging device (1); detecting, in the course of a gaging operation, a current reading (X) of the gaging device (1); detecting, in the course of the gaging operation, a current temperature (T) of the gaging device (1); determining, in the course of the gaging operation, the current value of the thermal compensation coefficient (K) by means of the values of the thermal compensation coefficient (K) previously determined and stored in the course of the calibration operation as a function of both the current temperature (T) of the gaging device (1) and the current reading (X) of the gaging device (1); and correcting, in the course of the gaging operation, the current reading (X) of the gaging device (1) by means of the current value of the thermal compensation coefficient (K).
