Abstract
The invention relates to an optical measuring device, more particularly for measuring turbidity in a medium comprising a housing, more particularly of metal, at least one sensor arranged in the housing including at least one radiation source for beaming at least one optical beam into the medium to be investigated, and at least one detector for detecting the scattering or reflections of the beam in the medium, at least one optically transparent element in a housing wall for beam emergence/incidence from/into the housing, at least one vibrator mechanical coupled at least to the optically transparent element, wherein a) the vibrator is arranged between the sensor and the optically transparent element, and b1) the vibrator contains at least one opening or passageway for beam passage and/or b2) the beam is steered between and through parts of the vibrator(s) into/out of the housing. This achieves a compact optical measuring device for reliable measurement even in heavily polluted media.
