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.
