13. PSC Sensor Performance
• Accuracy: (subject to application and product type)
– lab method, sampling technique, sensor location and
real-time process variability are all additional variables
to consider
– Moisture Range +/- 0.1-1.5%
– Response Time: 1-999 seconds
– Repeatability: +/- 0.2%
• Lamp Life 5-10+ years.
• Stability
– Excellent: +/- 0.1%/yr
• Height Sensitivity
– 15-40 cm (6-16”) Excellent

14. MCT300-WP State-of-the-Art
* Maintenance Free
Single Circuit Board
sensor design

15. Superior Single Detector Design
• An Advanced Feature. A single
thermally cooled detector circuit
maintains integrity and
robustness of both the internal
and external signals eliminating
erroneous readings due to
external effects differing the
detector response over time

16. Excellence in Measurement
* Backscatter, Single or Multi-Component intelligent NIR gauge
* Unrivalled measurement accuracy, stability and capability
∗ high speed measurement offering enhanced accuracy
∗ up to 3 component analysis
* Pre-calibrated measurements
* Calibrated on % wet weight and measure % wet or dry wt.
* Easy to use, Multi-lingual Operator Interface
* Active diagnostics
* No Routine Maintenance
* Networking gauge using “AnyBus” communication standards with
connectivity to the process. ProfiBus, DeviceNet, Ethernet Etc...
* Inbuilt cooling panel and product temperature

20. 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

21. 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.

27. •Installation
• Calibration

28. 5 Simple Steps
1) Precalibrate at Factory - Standard
2) Install On-Line
3) Run product at target moisture
4) Grab Samples and get lab values
5) Adjust Zero Trim offset

29. 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

30. 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.

31. 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
