ESTIMATION OF UNCERTAINTIES IN THE DISTANCE SENSOR CALIBRATION

R. Palencar, E. Kurekova

Abstract:

Calibration of the ultrasonic distance sensor is described in the paper. Measuring range of the sensor is 100 - 600 mm. Design scheme of the calibrating device is presented. The calibrating device utilises gauge blocks as a standard. Nonlinear mathematical model of the calibration is presented. Matrix method for the unknown parameters estimation is described. Analysis of the type A and type B sources of the uncertainties is given as well as their evaluation.
