Beta LaserMike LaserSpeed Non-Contact Gauge Measures Length & Speed with Highest Accuracy and Delivers Production Savings to Converters

NDC Technologies, a leading global provider of precision measurement and control solutions, indicates its Beta LaserMike LaserSpeed® non-contact gauge has helped numerous converters to accurately measure the length and speed of products during production to avoid costly product overages and shortages, as well as reduce product scrap and rework.

Converters of paper, film and foil products have applications where they need to tightly control the length and speed of product during production. Applications include continuous length measurement, differential speed control, cut-to-length control, product positioning, printing and coating application control, and other demands. Most manufacturers depend on the accuracy of their drive speeds or mechanical contact encoders. But, mechanical encoders can lose contact on various product surfaces due to slippage or web vibration, and require frequent calibration because of mechanical wear and tear. A contact encoder with inaccuracies as much as 2% can cost a converter a significant amount of money due to product give-away, waste, maintenance and system downtime. To solve this problem, manufacturers have installed the LaserSpeed non-contact gauge on their production line to directly measure the length and speed of product. It is a direct replacement for error-prone mechanical contact encoders.

The LaserSpeed gauge uses advanced, laser-based technology to precisely measure the length and speed of product during production without making contact with the material. It projects a unique pattern on the surface of the product. As the product moves, light is scattered back to the LaserSpeed gauge. This information is translated into product speed and pulses are produced to determine the product length. Length and speed measurements are captured with better than +/-0.05% accuracy and +/-0.02% repeatability. LaserSpeed gauges are used in a wide range of web and packaging converting processes for precisely measuring product length and speed at the slitter/rewinder, regulating coating/laminating applications, controlling critical length cutting operations, and monitoring web tension of products, to name a few. As a result of the higher measurement accuracy and tighter process control, converters are realizing a number of production efficiencies and savings.

LaserSpeed is available in a range of models with measurement speeds from 0.0 m/min up to +/-12000 m/min (39,400 ft/min), standoff distances up to 1000 mm (39.4 in), and measurement depth of field up to 100 mm (4.0 in). LaserSpeed models are also available to measure forward and reverse directions, as well as down to true zero speed (no motion). In addition, NDC Technologies offers a European certified length measurement system that meets MID (Measuring Instruments Directive) 2014/32/EU requirements.
