Laser diffraction sensors for diameter measurements Latest developments for very small wire Future developments

$15.00

The first sensors were developed between 1987 and 1988 to provide diameter measurement means working on-line for the steel cord industry. Recently CERSA has extended the range of measurement of these products to very small wires, down to 10 microns, with high accuracy. The results of trials in laboratory and factory are given. In the future, the company will develop, with the same principle, dies diameter measurement products and optical fiber diameter measurement.<
