The Proton InteliSENS SL non contact speed and length gauge offers an accuracy of 0.05 per cent – "far greater than encoders or tachometers," it is claimed. Using a Class 2 laser diode source and a proprietary geometric optical design, the gauge generates a laser 'doppler' pattern on the surface of the measured web. The reflected signal is then collected by receiving optics and processed by correlation DSP technology.
Said to be easy to integrate with existing control equipment, the new gauge's non contact technology eliminates the possibility of marking or damage to the product's surface, making it ideal for extensible materials such as thin film and for non woven applications. Measurement accuracy is unaffected by material surface or colour, so clear highly porous materials do not present a problem. It can therefore be used in the production of corrugated products, plastics films and tapes, textiles, foil, and for inkjet print/marking control.
With no moving parts, the Proton SL needs no calibration and can be used anywhere in a web based process that currently uses a pulley, roller, wheel, gear mechanism or encoder to measure speed, length or position. The gauge can be connected to drive or cut-to-length controls; communication options include Profibus, RS232 and Ethernet IP connectivity.
