    • A detector is provided for detecting the interruption of a light path, the detector comprising a light emitter, a light receiver, and a light guiding arrangement disposed opposite the light emitter and receiver. A gap is defined between the light guiding arrangement and at least one of the light emitter and receiver to receive a movable part capable of interrupting the light path there between. Also provided is a light guide for use with such a detector and a utility meter comprising such a detector. In one specific embodiment, an opto electronic detector for detecting rotation of a coding wheel in a utility meter is provided.
    • 提供了一种用于检测光路中断的检测器,该检测器包括光发射器,光接收器和与光发射器和接收器相对设置的导光装置。 在导光装置和光发射器和接收器中的至少一个之间限定间隙以接收能够中断其间的光路的可移动部件。 还提供了与这种检测器一起使用的光导和包括这种检测器的效用表。 在一个具体实施例中,提供了用于检测公用事业计量表中的编码轮的旋转的光电检测器。
