Laser Thickness Measurement Principle

The measuring principle of the sikora laser series 2000 and laser series 6000 is based on diffraction analysis.

Laser thickness measurement principle.

Thickness measurement with laser. A cmos array detects the position of the returned beam and is converted into a distance measurement. The eddy current principle is used in models marked with n or fn n non ferrous e g. Reporting using the latest in laser triangulation technology.

The eddy current principle enables the non destructive coating thickness measurement on non magnetic metal substrates eg. The ultra compact ar100 comes with ranges from 10mm 0 4 in to 500mm 19 7 in with a single case size. The laser thickness gauge with high response and high measurement resolution provides thickness measurement of the overall length including the top edge of the steel plate being conveyed. The ar100 is one of the smallest laser measurement sensors in the world.

It is a turnkey solution which utilizes two synchronized systems that moves in and out of the pipe on either side. It provides fast and reliable thickness measurements and s p c. The laser projects a beam of light onto a surface which is then reflected back. Thickness is the simplest measurement done with laser sensors.

A fan shaped laser beam is directed onto a high resolution ccd line. Ultrasonic wall thickness measurement operating principle ultrasound is a pressure wave with a frequency greater than the upper limit of human hearing approximately 20 khz. The basic components of a laser ultrasonic system are a generation laser a detection laser and a detector. The laser thickness gauge is susceptible to the effect of mechani cal deformation due to temperature changes and vibra tion.

It is a non contact technique used to measure materials thickness detect flaws and carry out materials characterization. The agt800 laser pipe pole measuring system is designed for measuring wall thickness. Direct benefits realized through these measurements include. Laserlinc uses ultrasonic frequencies from 2 25 mhz to 50 mhz.

Laser ultrasonics uses lasers to generate and detect ultrasonic waves. The microtrak 3 tgs system uses the principle of laser triangulation to perform a one dimensional measurement of a target. Aluminium aluminium alloys lead bronze copper brass zinc die cast zinc tin. It can take 9 400 measurements per second and has a linearity of 0 05 of the full measurement range for most models.

The thickness value is detected to micrometer accuracy using only a single sensor. Besides measuring the diameter of a round product laser based measuring devices can also be used for measuring a wall thickness. When deciding the best way to measure thickness it is important to consider factors such as the material target and type of measurement range accuracy speed. Laser measurement sensors measure thickness of materials.
