Micro-Epsilon Group Transmission Sensor for Translucent Objects colorSENSOR CFS3-A11

With the transmission sensor, the light emitted by the controller is sent from one side (backlight) at an angle of 180° (parallel) to the surface of the object to be tested. The transmitted light component (material color) of the sample is detected by the sensor from the opposite side at 0° (parallel) to the surface and transmitted to the controller via an optical fiber. Backlighting also makes it possible to measure in relative terms the colors of liquids in a glass tube or glass body, such as apple juice or detergent, with a repeatability of ΔE ≤ 0.3. The sensors are available with different ranges (distance between transmitter and receiver) and different spot sizes. Other working distances, sheaths and cable lengths are optionally available. The transmission sensor enables the measurement of transparent and semi-transparent products such as filters, films and optical lenses. The measurement arrangement in transmitted light 180°:0°, combined with the performance of the CFO series, provides even more precision. Here, the fluctuating distance between the test object and the receiver or illumination has no noticeable influence on the measurement result. The transmission sensor can be universally used but is also suitable for special solutions (customer-specific adaptions). Due to the standard FA connection, the optical fiber is also compatible with other controllers (previous series such as LT or WLCS). The transmission sensor offers many advantages in terms of performance and installation possibilities. Due to the external controller, less installation space is required at the measuring point.
