| Abstract: | Operational principle and high-speed calibration system of intelligent combinatorial eddy-current sensors based industrial computer are presented in this paper. The system can automatically fulfill channel selection, zero excursion restriction and modification error automatically, and measure multi-point displacement rapidly and accurately. It can also calibrate measuring channels in short period of time rapidly. The influences of temperature on precision of sensors temperature and digital filtering on noise signal are also analyzed. |
