TSorter – Thickness and width measurement system for correct sorting

TSorter is an in-process non-contact thickness and width measurement system. It is a complete stand-alone measurement system and can easily be exchanged or be integrated with different types of control systems in any sorting line


Basic Specification

Board shapesBoard dimensions
SquaresMinimum: 3 x 30 x 500 mm (0.1” x 1.2” x 19.7”)
Maximum: 300 x 1.000 x 6.000 mm (11.8” x 39.4” x 236”)

Operating Principle

LIMAB TSorter is equipped with two PreciCura lasers using the principle of optical triangulation. The sensors are placed against each other to ensure high measurement accuracy even with heavily bouncing boards. Almost any wood surface can be measured insensitive to color variations.


The TSorter measures thickness and width of any type of boards, planks or panels in a transversal or lineal process for sorting.

Control of average dimension
The TSorter measures the thickness and/or width of any types of boards, planks or panels in a transversal or lineal process for control of average dimension.

Sensor set-up
The TSorter measures the product thickness by using two PreciCura laser sensors. The sensors can be any model from the PreciCura range whether SR, MR or LR. The width as well as thickness will also be measured by connecting an optional encoder.

Non-contact measurement
The laser measuring principle ensures that the product is measured without contact. There is no product compression, scratches, dirt marks or wear.

Measurements are displayed and used for sorting, verification and product size documentation. The system is equipped with a display and keyboard for displaying the measured values as well as help during calibration and installation.

High accuracy
The system always deliver 0,10 mm (0.004”) thickness accuracy, even with bended boards or effects from vibrating older conveyors.

A sophisticated statistical filter helps to ignore splinters and other surface irregularities to improve measurement accuracy.

The display gives the user a feedback that the system is working correctly. It also shows main output data of thickness and width.

Simple integration
Easy to install in new and existing production lines.

No moving parts, no mechanical wear, long durability.

Non-contact measurement for best results                      .

The system can use any of the PreciCura SR/MR/LR sensor depending on the distance to the target.
