Specifications

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

MCT300-WP State-of-the-ArtSingle Circuit Board

sensor design

* Maintenance Free

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

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

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

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

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

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
