TSorter - Sawmill thickness gauge
The TSorter is a non-contact thickness and width measurement system for sorting of wood in sawmills. The timber can either be in the green or dry condition is measured in-process on the transverse conveyor.
|Thickness range||Thickness accuracy||Width accuracy (typical)||Laser measuring rate|
|0-200 mm||±0.1 mm||±1.0 mm||2000 Hz|
The thickness is measured with two PreciCuraSR sensors which use the principle of optical laser triangulation and will measure to any type of wood material. The width is measured by measuring the time the board takes to pass the lasers.
- Thickness measurement of planks on a transverse conveyor
- Thickness and width grading of wood
- Green timber sorting
- Thickness at planers
- Width and thickness sorting of sawn timber
The TSorter uses LIMAB’s standard PreciCura laser triangulation sensors which are a product of over 25 years experience of producing precision laser sensors. The unique laser sensors are robust, rugged yet very accurate and stable.
The laser measuring principle means that the timber is measured without contact. This eliminates regular maintenance and saves time and provides more reliable results.
Total process control
Continuous in-line monitoring of the timber thickness and width provides total process control allowing the boards to be graded and or sorted very efficiency.
Control system integration
The measurements from the TSorter can be used by the sawmill control system as part of the plant automation to improve efficiency and yield.
LIMAB provide a complete turn-key solution, one contractor takes full responsibility. The TSorter includes all the hardware and software needed for any factory installation. LIMAB provide commissioning, training and on-going product support and service.
