The optical micrometer family is now composed of two groups. Firstly, the well-known optoCONTROL ODC sensors: They perform such measuring tasks as edge detection, turbidity, position in the light band or segment detection with the aid of a light curtain between transmitter and receiver.
The sensors of the optoCONTROL CLS-K series are a new arrival: These also work with a transmitter and receiver - though together with a light guide.
The electronic circuitry of the CLS K sensors is mounted at a certain distance to the object, while the flexible light guide is led directly to the object. There the sensor works on the transmitted light principle, similar to a light barrier or - when in reflex mode - like a push-button. This arrangement results from the nature of the measuring system if, for example, the object does not allow transmitted light operation. Optical fiber micrometers are simple sensors for determining dimensional sizes as gaps or edges. The sensors are also suitable for objects made of glass when a UV light source and appropriate fiber-optic cables are used.
