| Title of Invention | VISIBLE WAVELENGTH LASER DIODE BASED DIAMETER GAUGE. |
|---|---|
| Abstract | Visible diode laser based diameter gauge with large stand off distance adapted for non-contact method of on-line measurement especially for use in stand rolling mills having means for extending the distance between source and detection upped about 5 mitres or so, visible laser diode for simplified installation and adapted for large stand-off measurement, means for detecting the presence and absence of moving rod/bars in steel rolling mills and the like, means for estimating the ovality/shape of the rod. The non-contact method of on-line diameter measurement is very much useful in steel rolling mills for bar and rod products in measuring the diameter/width of the rod/bar. It is also useful in wire and cable industry for on-line inspection and measurement of the diameter of cables and wires. It can also be applied in cigarette industry for measuring the circumference of the cigarettes. The non-contact method is useful where the object is moving or very hot. |
