ABSTRACT:
The invention relates to a waste water immersion probe (10) comprising a liquid-tight housing (11), a sensor (18) which is disposed in the housing (11) and a sensor window (20) formed on the housing (11). A wiper element (22) for cleaning the sensor window (20) is arranged on the outside of the sensor window (20), and the wiper element (22) is driven by a drive motor (24) which is arranged essentially in the housing (11). The housing is devoid of openings. A magnetic element (36, 37) is associated with the drive motor (24) and a magnetic element (34, 35) is associated with the wiper element (22) in such a manner that the magnetic drive motor element (36, 37) produces a magnetic field which transverses the housing wall and transmits a drive torque to the wiper element (22) without a shaft.
