Title
(EN) SMART LINEAR ANGULAR POSITION SENSOR
(FR) DETECTEUR INTELLIGENT DE POSITION ANGULAIRE LINEAIRE
Abstract
(EN)
A smart angular position sensor includes electronic circuitry (300) for automatically compensating for errors in the output signal of the sensor. The electronic circuitry (300) includes an electronic memory (306) for storing predetermined compensation values used to compensate the output signal of the sensor. The predetermined compensation values are determined by comparing the output signal of the sensor with ideal values at predetermined angular positions. The deviation of the actual values relative to the ideal values is used in determining the compensation values. The compensation values are stored in the electronic memory (306) and are used to automatically compensate the output signal of the sensor.

Le détecteur intelligent de position angulaire linéaire comporte des circuits électroniques (300) afin de compenser automatiquement les erreurs survenant dans le signal de sortie du détecteur. Les circuits électroniques (300) se composent d'une mémoire électronique (306) servant à stocker des valeurs de compensation prédéterminées utilisées pour compenser le signal de sortie du détecteur. Ces valeurs sont déterminées en comparant le signal de sortie du détecteur avec des valeurs idéales à des dispositions angulaires prédéterminées. L'écart entre les valeurs réelles et les valeurs idéales sert à déterminer les valeurs de compensation. Ces valeurs de compensation sont stockées dans la mémoire électronique (306) et sont utilisées pour compenser automatiquement le signal de sortie du détecteur.
