Sensors of luminescence: they allow to detect invisible marks to the human eye
The sensors of luminescence issue light UV with a wavelength of 380 nm. If the light issued strikes a luminescent object reflects light inside a rank of wavelength of 420 – 750 nm in accordance with the luminescent substance used. This fluorescent effect is used by the luminescent sensor to detect marks that invisible to the human eye.
Applications:
- Checkup by presence of labels
- Alignment of aerosols without visible marks
- Verification of authenticity of the product (detection by contrast)
- Control of saws in the industry of carpentry
luminescent Substances: the luminescent substances can be applied to almost all(ej. Labels and cardboards), and can be added to a lot of substances such like ink, oil or fat. The use of an optical filter makes possible to select which rank of wavelength (that is to say, which colour) will be visible for the sensor.
You adjust them they are realizar with pulsadores of the Teach-In, with Teach-In external or through RS-232.
Through the interface RS-232 can activate the functions of the sensor. Incidentally it can extract the value of intensity of the light.
