Amelioration of the resolution of a high precision electronic inclinometer Nivel20

Abstract

This paper presents a method to ameliorate the resolution of an electronic inclinometer Nivel20 which has resolutionone micro-radians (≅ 0.0000573 degrees) with the addition of the measuring position for the average of repeatedmeasurements. Using the piezoelectric to achieve a change in slope that is lower than its resolution. Capacitivesensor is used to measure the first step distance for the compensation system and system design software isused for automatic movement in the experiment. The results show that before the compensation, the accuracy ateach measurement position is ±2.5 micro-radians and after the compensation, the accuracy is ±0.15 microradiansthat is smaller than its resolution three times.
