Abstract: A sensor positioning device, having a holding module, with a sensor receptacle, fastening element and spring element, the sensor receptacle being mounted movably relative to the fastening element along a compensating axis. The spring is arranged between the fastening element and the sensor receptacle to cooperate therewith, to create a restoring force during movement of the receptacle relative to the fastening element. A measurement connector with an abutment is configured for arrangement onto a process container, and is configured for releasable arrangement on the holding module. The sensor positioning device is configured such that, when the measurement connector is arranged on the holding module, the sensor receptacle is movable relative to the fastening element along the axis, and a pressing force of the sensor receptacle onto the abutment of the measurement connector is created by the spring. A sensor unit, for turbidity measurement, is provided having the sensor positioning device.

Abstract: The invention relates to an interchangeable fitting with a fitting housing (12), a removable measurement probe (14) which is movably guided axially in the housing (12) for insertion into a container, a shut-off element (16) which closes the fitting (10) relative to the interior of the container, and a guide means (22) which can be guided to move axially in the housing (12) for holding and guiding the measurement probe (14) in the fitting housing (12) between a measurement position in which the measurement probe (14) has been inserted into the container, and a stand-by position in which the measurement probe (14) is located within the fitting housing (10), the measurement probe (14) comprising a measurement probe body (15) and a sensor (26), the measurement probe (14) being fixed with its measurement probe body (15) on the end face (23) of the guide means (22), and the sensor (26) being mounted on the free side of the measurement probe body (15) which points in the direction to the container and the cross sect
