TSorter

Sawmill Thickness Gauge

Overview

The TSorter is a non-contact sawmill thickness and width measurement gauge for sorting wood in sawmills. The timber can either be in the green or dry condition is measured in-process on the transverse conveyor.

Operating Principle

The thickness is measured with two PreciCuraSR sensors, which use the principle of optical laser triangulation and will measure any type of wood material. The width is measured by measuring the time the board takes to pass the lasers.Sawmill Thickness Gauge

Application

  • 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

PreciCura Technology

The TSorter uses LIMAB’s standard PreciCura laser triangulation sensors, which are a product of over 25 years of experience in producing precision laser sensors. The unique laser sensors are robust, rugged yet very accurate and stable.

Non-Contact Measurement

The laser measuring principle means that the timber is measured without contact, eliminating regular maintenance, saving time and providing more reliable results.

Total Process ControlSawmill Thickness Gauge

Continuous in-line monitoring of the timber thickness and width provides total process control allowing the boards to be graded and or sorted very efficiently.

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.
