Eddy current probe for measuring the approach distance of an electrically conducting object has temperature compensation for the probe connection cable in the form of an additional compensation cable

摘要

Circuit arrangement (1) for temperature compensation of an Eddy current approach sensor in which the sensor (2) is linked to the analysis unit (3) via a connection cable (4). To compensate for temperature change effects affecting the connection cable a compensation cable (5) is provided. An Independent claim is made for a temperature compensation method for an Eddy current approach probe in which the effect of temperature variations on the connection cable between the probe and the analysis circuit is compensated using a compensation cable.
