sets standards in long term accurate, non-contact speed and length measurement.


Being capable to measure speed and length with a typical accuracy better +/-0.3% (1σ;length>5m), VLF262 is the ideal gauge for replacing contact tachometers which tend to measurement errors caused by slippage, chatter or vibration, dirt build-up and day to day wear problems. The most compact and easy to handle in class VLF262 uses proven laser doppler technology. Thus it has no moving parts, is maintenance free and permanently calibrated, resulting in significant time and money savings. Beeing designed for machine integration, the smartsensor does not use a external processing unit like the standard VLF260 system.

VLF262 works at almost any moving objects, such as web, coils, tubes, rods, sheets, plates,… and is suited for a wide range of applications, including continuous online control, cut-to-length control and differential speed measurement of:
• Textile, non-woven and leather
• Steel, aluminium, metal
• Wire, cable and fibre
• Plastic, film, foil and tape
• Paper and corrugated products
• Rubber and synthetic materials
• Wood, glass, ceramics

• Direct replacement for tachometers
• Non-contact measurement
• Non-marking, no slippage
• Independent of mat., surface, colour
• High accuracy and repeatability
• No parametration necessary
• Permanently calibrated
• Compact package; easy to handle
