Wood Moisture Measurement Locations
Measurement of:* Moisture 0 – 35%
- Forming Lines * Core/Face - Blender - Dry/Wet Bins - Blenders - Dryer Input/Output
* Particleboard/MDF - Weigh Belt* Green Wood Moisture
- Incoming/Wet bin storage* Resin Trending (Phenol, MDI,
Urea)* Wax Trending

Reasons for Moisture Measurement in Wood
Fiber• Quality Control
–Consistent Board Quality• Improved Dryer ,Press and Blender
Operation & Control–Drying Efficiency –Blending Efficiency–Energy Savings
• Weight Belt
- Use % moisture to correct weigh belt.

•Installation
•Calibration
![Page 28: Wood Composite Industry Psc Presentation](https://reader035.fdocuments.in/reader035/viewer/2022062614/54670562af7959ba5e8b488f/html5/thumbnails/28.jpg)
5 Simple Steps
1) Precalibrate at Factory - Standard
2) Install On-Line3) Run product at target moisture4) Grab Samples and get lab values
5) Adjust Zero Trim offset
![Page 29: Wood Composite Industry Psc Presentation](https://reader035.fdocuments.in/reader035/viewer/2022062614/54670562af7959ba5e8b488f/html5/thumbnails/29.jpg)
Pre - Calibration • Pre - Calibration at PSC factory with
Customer supplied samples.
• Trim offset needs to be fine-tuned online at target moisture–Due to differences between the online
process dynamics vs. lab environment–Possible differences due to lab
methods
![Page 30: Wood Composite Industry Psc Presentation](https://reader035.fdocuments.in/reader035/viewer/2022062614/54670562af7959ba5e8b488f/html5/thumbnails/30.jpg)
Easier Customer Calibration - Calibration
Transfer• All sensors can have the same span–Same sensor –Detectors have same output
characteristics –Same algorithm, filters, settings–Same application, product
• Zero needs to be fine-tuned at target–Small differences between sensors
taken out with Zero offset.

Calibration Check Standards
• Use to verify instrument stability.– Can be used for calibration
transfer
• How Many ?– 1 check: Good– 2 checks: Better (Span and Zero)– 3 checks: Redundant
