Optical sensor i.e. turbidity sensor, for use in e.g. dishwasher, of household equipment, has light-sending and light-receiving elements arranged in subspace of housing interior, and measuring section running on part of route distance

摘要

The sensor (10) has a measuring component (38) with a light-sending element (40) and a light-receiving element (42). The component is arranged in a housing interior, and defines a light measuring section (16) running from the light-sending element to the light-receiving element. The component runs on a part (18) of route distance outside the housing. The light-sending element and the light-receiving element are commonly arranged in a first subspace (70) of the interior. The measuring section runs on the part of the route distance through second and third subspaces (72, 74) of the interior.
