MCT466-QC NIR Tester Description
3.1.
NIR tester Components
The MCT466-QC NIR tester is a reliable and sturdy at-line NIR device for use in harsh environments.
The MCT466-QC NIR tester is routinely used to measure moisture in samples taken from the production
line. However, other measurements can be made including oils, protein, film thickness, coating weights,
nicotine and sugars. The following are the main components of the MCT466-QC NIR tester:
3.1.1.
Light Source
A quartz-halogen light bulb running at reduced voltage generates infrared energy.
3.1.2.
Filter Wheel
Six infrared and visible filters are held in a circular disc. A single timing notch is machined in
the edge of the disc.
3.1.3.
Filter Wheel Motor
A precision brushless DC motor is used to accurately rotate the filter wheel in front of the
infrared light beam.
3.1.4.
Detector
A PbS (Lead Sulfide) detector is used to convert the infrared light energy into electrical pulses.
3.1.5.
NIR tester Electronics
The MCT466-QC NIR tester contains the following electronic components:
Power Supply:
A 90-260-volt auto selection supply provides DC power to operate the
NIR tester.
Main Board:
Single PCB “smart” circuit board containing central processing system,
analog and serial communications.
3.1.6.
Smart User Interface
High resolution 5.7” touch screen color display providing all set up, calibration and diagnostic
data from the tester. (Go to section 3.2 for details on the SUI)
