Wooden Door Online Thickness Measurement Posted in: AR700 Laser Displacement Sensor – Tags: , ,

One of Acuity’s customers manufactures wooden door at a rate of over 4,000 doors a day. The quality, fit and finish of the door must be as perfect as possible.

One of the issues doors can have is that they are too thick or too thin for a good fit in the door jamb. This customer is using 3 sets of Acuity AR700-4 laser displacement sensor in a dual opposed mode to make the thickness measurements to hold several thousand’s of an inch as the doors move down the conveyor line.

The line speed is about 3 feet a second and the AR700 models can easily measure thickness over 500 samples per second to provide a complete profile of the door as it is processed.
