Laser Thickness Measurement Principle

The ar100 is one of the smallest laser measurement sensors in the world.

Laser thickness measurement principle.

Laserlinc uses ultrasonic frequencies from 2 25 mhz to 50 mhz. It is a turnkey solution which utilizes two synchronized systems that moves in and out of the pipe on either side. The laser projects a beam of light onto a surface which is then reflected back. 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.

Laser measurement sensors measure thickness of materials. Direct benefits realized through these measurements include. One sided thickness measurement of transparent materials. Laser ultrasonics uses lasers to generate and detect ultrasonic waves.

A fan shaped laser beam is directed onto a high resolution ccd line. The confocal chromatic measuring principle enables thickness measurements of transparent materials such as glass. The eddy current principle is used in models marked with n or fn n non ferrous e g. The microtrak 3 tgs system uses the principle of laser triangulation to perform a one dimensional measurement of a target.

The laser thickness gauge is susceptible to the effect of mechani cal deformation due to temperature changes and vibra tion. The controller provides an editable expandable materials database. Thickness is the simplest measurement done with laser sensors. Besides measuring the diameter of a round product laser based measuring devices can also be used for measuring a wall thickness.

It can take 9 400 measurements per second and has a linearity of 0 05 of the full measurement range for most models. The ultra compact ar100 comes with ranges from 10mm 0 4 in to 500mm 19 7 in with a single case size. Reporting using the latest in laser triangulation technology. Aluminium aluminium alloys lead bronze copper brass zinc die cast zinc tin.

A cmos array detects the position of the returned beam and is converted into a distance measurement. 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. It is a non contact technique used to measure materials thickness detect flaws and carry out materials characterization. The eddy current principle enables the non destructive coating thickness measurement on non magnetic metal substrates eg.

The basic components of a laser ultrasonic system are a generation laser a detection laser and a detector. The thickness value is detected to micrometer accuracy using only a single sensor. The measuring principle of the sikora laser series 2000 and laser series 6000 is based on diffraction analysis. 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.
