Abstract

George Kelk Corporation, Toronto, Canada, has introduced a new sensor, the ACCUSPEED Laser Velocimeter, which represem the state-of-the-art in rolling mil speed measurement. ACCUSPEED offers several advantages over traditional laser doppler velocimeter (LDV) systems. LDVs are subject to a 'scatter' which has been measured to be as high as 3% of the reading. ACCUSPEED is not subject to this error, and can measure instantaneous velocity with an error less than 0.1%. This feature makes ACCUSPEED ideally suited for critical control applications, such as mass-flow AGC. ACCUSPEED's compact Optics Head is designed to be mounted 2,100 miliimeters(82.7 inches) above the material to be measured, twice the standoff distance of LDVs. Using a periscope assembly, it is also possible to locate the Optics Head above or below the strip with a shorter standoff distance. ACCUSPEED was originally designed for use as part of KELK's ACCUBAND Crop Optimization System. As such, ACCUSPEED's components were designed so they could be used in hot strip mill applications without requiring additonal environmentd protection. A unique User interface program gives quick and convenient access to ACCUSPEED during instaiiation, operation, and service. It incorporates a Configuration Module, an Operations Monitor, and a Diagnostics Module.
