  • Product name: Bit cutter diameter measurement
  • Product number: LSG-1040
  • Added time: 2016-03-05
  • Retail price:

Laser scan micrometer LSG-1040S


1, Outline of LSG-1040S:

Product use optical scanning measurement method, non-contact measurement method to measure the objects of diameter, width and thickness, ovality. Product is suitable for wire, cable, pipes or rods on-line measurement and monitoring. Product is suitable for quality inspection, material classification etc. Instrument has external access interface can be accessed DPM series displayer and controller, PLC or computer.

2, Principle of measurement,

The laser beam emitted from the semi-conductive laser “a” is deflected by the fast rotating octoangular prism “b” driven by the motor “c”. After scanning and passing the lens “d”, the beam becomes a beam of parallel light running through the measurement zone (gate). If the object to be measured “e” is located in the gate, it will block part of the parallel light. After the parallel light is transmitted through the focusing lens “f”, the blocked part will be transformed into a low level electric signal while the unblocked part will be transformed into a high level electric signal by the photoelectric tube “g”. The outer diameter of the tested object in the direction of the scanning light may be calculated from the scanning time of the low-level electric signal.
