Abstract: A compressed air conditioning apparatus (2) and a load control device (1) equipped therewith are proposed, the compressed air conditioning apparatus (2) comprising a switch-on valve (14) with 3/3-valve functionality. By means of the switch-on valve (14), an outlet passage (22) leading to a load device (A) can, among other aspects, be optionally supplied with compressed air or disconnected from the compressed air supply. By means of a pressure sensor (24) and/or a flow sensor (25), actual pressure and/or flow data can be recorded and compared to reference data previously stored in a teaching mode. As a function of the comparison result, an electric diagnostic signal can be generated, offering, among other aspects, the opportunity for monitoring leakage from the load device (A) or excessive air consumption.

Abstract: 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.
