The metals fabrication business is one of the oldest industries in the world. Large mills are automated, but some smaller mills still rely on hand-held micrometers to gage metal thickness. AR200 laser measurement sensors are ideal 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 based on a simple mathematical formula that takes into consideration the separation distance of the two sensors.

The limit swithces on the AR200 sensors can be used to detect the location of a lap welds where two strips are joined.

The CMOS detector in the AR200 allows the sensor to accurately measure to a variety of colors, including dark steel.
