Abstract
The device is constructed to position a measuring sensor, especially a sensor head at an angle to a sensor shaft, precisely at the point of measurement and in the direction of a fluid flowing in a test tube, in which there is an adjuster through which the measuring sensor, in a coaxial arrangement, can be adjusted via a first adjusting motor about its axis and/or by a second adjusting motor along its axis. A control device communicates with an electronic computer for controlling the sensor adjustment. An adjuster (4) is coupled to the sensor to rotate in unison therewith and has a rotatable pendulum which, in the position of rest transversely to the test tube axis defines the zero position of the sensor. Limit positions of the pendulum are predetermined from a relative movement of the adjuster about the axis which can be photometrically converted into position signals. The computer mathematically halves the angular adjustment calculated from the position signals received and sets the adjuster with the sensor to mechanical zero by the respective positioning stop command signals.
