Evaluation of measurement uncertainty of dynamic calibration device for linear displacement sensors
At present,the existing methods for calibrating linear displacement sensors are static and dis-continuous measuring methods,which have shortcomings such as low efficiency and poor accuracy.This article designs a dynamic calibration device for linear displacement sensors based on a laser interferometer as the main standard,and evaluates the measurement uncertainty of the device.The results show that the device effectively improves calibration efficiency and accuracy.
