Log Scanner specifications

The Log Scanner is built on the same X-ray principles as the Flow Scanner and covers the conveyor belt between the debarking drum and the chipper.

The standard product can be configured for different tree types, flow rates, temperature ranges, belt specifications, interface requirements and area restrictions. Modifications and customisations can be made to the existing design for site specific installation requirements. 

Harsh environment?

Don’t worry. We have a number of optional compatible heating and cooling units to handle the toughest environments.

Heating unit

Internal regulated heating of critical elements to cover ambient temperatures below +10 ℃ but higher than -10 ℃.

Large heating unit

Internal regulated heating of critical elements to cover surrounding temperatures below +10 ℃ but higher than -20 ℃.

Cooling unit

Internal regulated additional cooling units for critical items, plus increased internal heat exchanger capacity, for surrounding temperatures up to 50 ℃.

Foreign object detection accuracy
The confidence of detecting foreign objects depends on type of log flow and is related to what rate of false detections is acceptable. Typically above 95 %.

The Log Scanner is extremely robust with up-times exceeding 99 %.

Radiation safety
Complies with local legislation for personel protection. Shut-off when entering belt area for removing objects. Emergency stop. Safety interlocks for service maintenance.
