LASCAN DIA GAUGE
Lascan dia gauge is a good import substitute. It is a laser based non-contact diameter measuring instrument ideally suitable for high temperature, toxic radioactive or soft materials. It can be used for on-line measurement, process monitoring and control.
It is based on the principle of beam scanning. A fine beam of visible light from a laser diode is reflected by a high speed-rotating mirror on to a lens to produce parallel scanning beams. These parallel beams after interacting with the object are focused by receiver optics on to a photodiode. Any object kept in the measuring plane will obstruct the scanning beam for a period proportional to its dimension. The parallel beams are then focused by optical means on to a photodiode to generate a shadow pulse of the object, which is electronically processed to give the dimension of the object.
