Sensors
The operation of the colorSENSOR CFO controller requires sensors which are used at the measuring point. Depending on the measurement task, the sensors can be individually combined. Moreover, these high-quality sensors with glass fibre optics are characterized by small installation dimensions and robust materials. This makes them particularly suitable for mechanical stress and harsh ambient conditions such as high temperatures. Since the sensor head requires only little space, the sensor can also be used in confined conditions.
The angular illumination of the CFS1 enables a punctual illumination of the measuring object without influencing the surface. As a result, only the diffusely reflected portion of the surface colour is detected. The measuring arrangement is best suited for high-gloss and diffusely reflecting surfaces, since the direct reflection (surface gloss) does not influence the measurement.
In combination with the performance of the CFO controllers, the ring illumination delivers even more precision thanks to uniform illumination. This compact combination can be used universally, but is also suitable for special solutions (customer-specific adaptations). The homogeneous illumination offers advantages especially on strongly structured or shiny metallic surfaces and provides highest precision in colour differentiation of, e.g., white tones.
The transmission sensor can be used to measure transparent and translucent products such as filters, films and optical lenses. The measurement arrangement in transmitted light 180°: 0° provides even more precision in combination with the performance of the CFO controllers. Here, the distance variation between the test specimen and the receiver or illumination has no noticeable influence on the measurement result. The transmission sensor can be used universally, but is also suitable for special solutions (customer-specific adaptations).
The reflex sensor, in combination with the performance of the CFO controllers, provides even more precise distinction of the surface characteristics of materials. The measurement arrangement in the reflective sensor of the transmitter and receiver in 0°: 0° enables quality control not only based on colour, but also in combination with the reflection properties of the product surface. This is needed, for example, when sorting different materials such as stainless steel, steel, tin, zinc, aluminium, brass, gold or other colored parts.
