Optische Sensoren / Faseroptische Sensoren / Fiber Units

Faseroptischer "clamp-on" Füllstandsensor, für zuverlässige Überwachung ohne Medienkontakt bei minimalen Installationsaufwand. Limited space is a frequent concern in a wide range of industries. As a result, space saving has become an important aim of Azbil's fiber units. Several types exist: ◾Cylindrical shape is suitable for installation when space is limited, by attaching with the setscrew. Azbil's HPF-T038 is the smallest fiber unit head dia. (1.0 mm) in the industry. ◾Sleeve shape is used to maintain a small distance between the target object and the sensor in limited spaces. ◾Side view shape emits light to the side, its D-shape cut-out on the fiber unit head greatly reduces installation time and the time it takes to perform additional adjustments. ◾Flat shape is attached directly to the casing, additionally the cable lead-out is selectable from 4 directions. ◾If precision is your main concern, azbil's Coaxial shaped fiber unit is recommended for target object positioning or in combination with micro-spot lenses and other applications requiring highly precise positioning. ◾Improving detection performance yields many positive results. Because of irregular reflection inside a lens, some light is returned even when no workpiece is present, but it is a small amount compared with the light reflected when there is a workpiece. In HPF-LU sensors, the internal wall of the lens has a special feature that keeps this internal reflection to a minimum, so there is an increased amount of difference in light level when a workpiece is actually present. ◾Problems due to scratches on the lens are greatly reduced The micro-spot lens is made of hard glass, so problems caused by a drop in light level due to lens scratches made by collisions with workpieces can be greatly reduced. ◾Azbil's fiber units portfolio also contains heatproof, chemical-proof and vacuum-proof fiber units, offering solutions to any kind of harsh environments.
