<p>Bearing with a magnetic sensor having a self-compensating detecting circuit, such as a velocity sensor applied to a bearing and to a rotating shaft, consisting of the combination of the following elements: a magnetic semiconductor sensor delivering an analog output signal proportional to the speed of rotation of the shaft, a bearing, mounted on the said shaft, a device for fixing the sensor on the bearing, an encoder with magnetic poles, whose poles are arranged alternately in such a way that each north pole is between two south poles and each south pole is between two north poles, a self- compensating detecting circuit for processing the output signal from the velocity sensor so as to obtain a numerical signal proportional to the speed of rotation of the shaft; this detecting circuit consisting on the one hand of a device compensating for external factors causing a drift of the output signal from the sensor and on the other hand including means for processing relatively small output signals from the sensor. …<IMAGE>… </p> |
