A servicing device and more particularly an oiler or a filter device, for the preparation of a pressure medium, which comprises a capacitive sensor having at least one first electrode responsive to at least one operational parameter of the servicing device. An expendable material and more particularly a filter means or an additive for such a servicing device, which is renewable and is able to be utilized by the servicing device for the preparation of the pressure medium and bears a capacitively detectable code means, on the basis of at least one operational parameter of the servicing device is detected. Furthermore there is a capacitive sensor for such a servicing device.

Servicing device and furthermore expendable material and a capacitive sensor therefor

A device for detection of angular positions of a shaft adapted to be rotated about its longitudinal axis. An actuating member keyed on the shaft moves along an arcuate path during rotation of the shaft. At least one sensor is adjustably secured by means of a holding means on an arcuate guide of a sensor carrier so that it may be positioned along the path of movement of the actuating member. In order to render possible accurate resetting, on the sensor carrier teeth are provided on the sensor carrier following the curvature of the arcuate guide, such teeth being engaged by a setting gear wheel rotatably mounted on the holding means. On turning the setting gear wheel the holding means connected with the sensor is shifted along the arcuate guide
