Metals fabrication is one of the oldest industries in the world. Large mills are automated, but due to cost constraint some smaller mills still rely on hand-held micrometers to gauge metal thickness. AR200 laser displacement measurement sensors from Acuity, USA are an ideal and a cost-effective way for measuring steel strip thickness to fine resolutions.

Steel passes between two opposing non-contact laser sensors. A computer or PLC receives the sensors' output and calculates a resultant material thickness. The calculation is based on a simple mathematical formula that takes into consideration the separation distance of the two sensors.

The limit switches on the AR200 sensors can be used to detect the location of lap welds where two strips are joined. The CCD detector in the AR200 laser allows the sensor to accurately measure to a variety of colours, including dark steel.

The AR200 laser has a resolution of up to 2 microns and a linearity of +/-0.2% of span. Users of the AR200 laser can configure the zero and span anywhere in the measurement range and set the sample rate from 0.2 to 1250 samples/ second. The AR200 laser comes calibrated and is simple to set up and use.
