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 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 di precisione di spostamento non-a-contatto, quale usare!?

The use of non-contact displacement technologies in the field of precision measurement is rapidly growing.

This rapid growth has pushed the development of new technologies, and also the adaptation of already existing technologies to meet the new measurement requirements and to improve measurement accuracies and resolutions.

It is therefore more important than ever to have a greater level of understanding of the strengths and limitations of each non contact measurement principle when selecting the correct sensor technology for the measurement task.

Nuovo laser di misura a 50KHz

Micro-Epsilon’s new high-end laser triangulation sensor is known as the optoNCDT 2300. The new series offers a measuring rate that can be set up to 50kHz. The sensor will be offered initially as a set of 5 models with measuring ranges between 2mm and 100mm. The new A-RTSC (Advanced Real Time Surface Compensation) feature is a development of the company’s already proven RTSC technology and, with its improved dynamic range, enables a more precise real time surface compensation during the measuring process.

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

Sensore di misura Magnetico-Induttivo fino a 45 mm

Micro-Epsilon's mainSensor (MAgneto-INductive sensor) is a new alternative in the field of wear-free distance measurement. The measurement object is represented by a small magnet, which can be easily attached via a hole drilled in any non-ferromagnetic support. Similar to Hall Effect sensors, the measuring principle is based on changes in the magnetic field strength.

Through a new method (patent-pending) there is a linear relationship between output signal and displacement change, and not between signal and magnetic field strength, as with a Hall Effect sensor. In this way, displacements of 45mm can be detected in high resolution.
