LaserSpeed models are also available to measure forward and reverse directions, as well as down to true zero speed (no motion).įor more information on the Beta LaserMike LaserSpeed non-contact encoder, visit About NDC Technologies and Beta LaserMike Products LaserSpeed is available in a range of models with measurement speeds from 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 (3.0 in). As a result of the higher measurement accuracies and tighter process controls, converters are realizing a number of production efficiencies and bottom-line advantages. LaserSpeed encoders 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. Length and speed measurements are captured with +/-0.05% accuracy and +/-0.02% repeatability. This information is translated into product speed and pulses are produced to determine the product length. As the product moves, light is scattered back to the LaserSpeed unit. This laser encoder projects a unique pattern on the surface of the product. The LaserSpeed encoder uses advanced, laser-based technology to precisely measure the length and speed of product during production without making contact with the material.
To solve this problem, manufacturers have installed the LaserSpeed non-contact encoder on their production lines to directly measure the length and speed of product.
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. 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. Most manufacturers depend on the accuracy of their drive speeds or mechanical contact encoders. Applications include continuous length measurement, differential speed control, cut-to-length control, product positioning, printing and coating application control, and other demands. LaserSpeed is widely meeting the converting industry''s growing demand for highly accurate product length and speed measurements, resulting in increased productivity, improved product quality, and decreased production loss.Ĭonverters of paper, film, and foil products have applications where they need to tightly control the length and speed of product during production. A data acquisition system effectively collects and processes the lay length data, and reports the measurement results.Orlando, Florida – Decem– NDC Technologies, a leading global provider of precision measurement and control solutions, will be exhibiting the Beta LaserMike LaserSpeed® non-contact length and speed encoder at ICE USA in Orlando Florida from February 10 - 12, 2015 at the Orlando Convention Center (Booth 901). Systematic lay variations that are typically caused by twinning and cabling operations can be readily observed and measured. Providing high-data rate capabilities, LayScan precisely determines the variations in lay length within each lay. The system uses optical, noncontact measurement technology to perform online, high-speed lay length measurements with the highest precision to within 1 mil. Beta LaserMike's LayScan system accurately and consistently measures the lay length of twisted pairs used in telecommunication cables.
