Uno strumento musicale basato su un sensore laser

I sensori laser a triangolazione della serie optoNCDT sono usati tipicamente in applicazioni industriali per misure senza contatto di spostamenti, distanze e posizioni. Presso l’Università di Brema in Germania, invece, il sensore laser è utilizzato per uno strumento musicale. Lo strumento è realizzato con un meccanismo rotante e un sensore laser di spostamento. Un qualunque oggetto può essere fissato nel dispositivo e ruota attorno al suo asse. Il sensore di spostamento scansiona la sua forma. L’informazione della distanza è convertita in una frequenza acustica e riprodotta tramite un altoparlante. Lo strumento può suonare un gran varietà di oggetti della vita quotidiana, in cui la sua forma determina melodia e ritmo. “Suonare questo strumento richiede un misto di esperienza, intuizione e coincidenza” spiega il Prof. Dennis Paul, il suo inventore.

Sensore capacitivo per misure di spazi e fessure (gap sensor)

The new capacitive sensors from Micro-Epsilon capaNCDT CSG are specially developed to measure gap width. Sensor electrodes are applied to the top front and back on a circuit board that has a width of 20cm. Using the sensor electrodes and the differential method, the gap width can be determined very precisely while moving the sensor into the gap. A special feature is the sensor’s flexible probe. This also enables the sensor to be used in applications where the measurement object is difficult to access. Using the capaNCDT CSG, gaps of 0.9mm up to 4.9mm can be measured at a resolution of up to 90nm. However, metal objects and a clean measurement gap are required for these sensors. In terms of the electronics for the capaNCDT 6500, signals of both electrodes are immediately calculated with the gap width. Furthermore, the sensor can be replaced or connected to any other electronics supplied by Micro-Epsilon. With the same sensor dimensions, the new capaNCDT CSE offers a measuring range that is 2.5 times larger. As the CSE sensors are equipped with a shielding electrode which is set back, the sensor dimensions are considerably smaller. Therefore, these sensors show significant benefits while also offering the same measuring range. Since the sensors are cylindrical in their design, and have a connector on the back, they are very flexible in terms of their use. As usual, the sensors can be either connected to any other Micro-Epsilon electronics or easily replaced.

Sensore laser di distanza a basso costo

Low cost laser distance sensor offers high reliability

The new optoNCDT ILR 1030 complements Micro-Epsilon's existing range of economical, low cost distance measurement sensors. The new sensor offers a measuring range between 0.2m and 8m on diffuse reflective surfaces, even as high as 50m when using a reflector plate. Special features of this model include its high measurement speed of 100Hz, which also enables length measurements with different objects in the measuring range, as well as the high reliability of measurements on different target materials.

The optoNCDT ILR 1030 is the smallest laser distance sensor in its class. The sensor operates on the time-of-flight principle. It is also insensitive to external light influences and can even measure under artificial lighting. The sensor provides a constant resolution over the entire measuring range. The sensor operates at temperatures between -30°C and 50°C. The full benefits of the optoNCDT ILR 1030's price advantage become clear with small to large OEM orders. The sensor measures with a visible, class II laser pulse, enabling easy alignment on the target. The sensor can be set up and configured directly using the keypad on the housing. The software provided enables the user to make additional adjustments.

Sensore laser di spostamento a luce blu

Displacement sensors with a blue laser

Micro-Epsilon presents at first a triangulation sensor that utilise Blue Laser technology. In numerous applications, Blue Laser sensors are superior to standard sensors that use a red laser diode. When measuring on metals, particularly annealing metals and organic materials such as wood, skin, foodstuffs, veneers, etc., the wavelength of the blue-purple laser offers significant benefits. In contrast to a red laser, the reduced wavelength of the blue laser light does not penetrate the measuring object. The blue laser generates a minimal laser point on the surface and therefore offers stable, precise results on measuring objects that are normally considered as critical. The design of triangulation sensors with Blue Laser technology is a complete re-design. The sensors are equipped with new high-end lenses, new intelligent laser control and evaluation algorithms. Laser sensors with Blue Laser illustrate the ongoing development of numerous standard commercially available laser sensors.

For example, the optoNCDT 1700 industrial standard laser sensor provides this new Blue Laser technology. Depending on the measuring object and measuring range, the appropriate sensor can be selected with either red or blue laser light.

Sensori a Filo Micro-Epsilon - Guida alle Applicazioni

Draw-wire displacement measurement is classified as a contact measurement method. Every draw-wire sensor consists of the basic wire elements, drum and spring motor (combined as mechanics) and a potentiometer or encoder for the measurement signal generation.

Draw-wire sensors are ideal for applications with large measuring ranges, small sensor dimensions and when a low cost solution is required. Depending on the sensor design, the wire is normally an extremely thin steel wire, which is sheathed with polyamide. The wire is around 0.8mm thick on average, depending on the type of stress forces involved.

Benefits of draw-wire sensors are:

- Very compact design compared to the measuring range

- Telescopic measurement principle

- Very robust sensors

- Measuring wire can be deflected using deflection pulleys

- Low cost solution
