Industrial Process NIR Applications
The MCT460 Online NIR Smart Sensor is used to continuously measure and control moisture, coat weight, film thickness, and product temperature during the manufacturing process. The sensors are capable of a closed-loop control of belt speed, paper re-moisturisers, and other processes where moisture variation is controlled. The MCT460 Series can also be easily integrated into existing control systems with industry-standard IO protocols, adding data to maximise process efficiency. Some examples of industrial products that can be measured are:
Typical Applications:
- Fertilizers
- Paper products
- Wood products
- Converting: hot melts, pressure-sensitive adhesives
- Tobacco
Additional Applications:
- Extruded plastics
- PVB film
- Textiles
- Crumb rubber
- PVC powders
- Ceramics
- Detergents, soaps
- Ore
- Biofuels
How It Works – Control Moisture to Within 1/10th of a Percent
The MCT460 Series NIR analyzers are integrated into key areas of a production process to continuously monitor incoming raw materials or control processes on the production line. Each option is designed to integrate seamlessly over belt conveyors, auger/screw conveyors, or bins & chutes to analyze moisture, oil, and other on-line measurements.
The MCT460 scanning process is simple but reliable:
- Light from the lamp is directed through a rotating wheel at 2000rpm containing NIR filters selected for the application
- NIR light is directed onto the product being measured
- The light reflected off the product is captured by a mirror within the unit and focused onto a Peltier Cooled Lead sulfide detector.
- The detector’s output is taken by the on-board “smart” circuit board and compares to the internal reference beam. This is then converted into a percent of moisture, oil, and other parameters.
System Components
The MCT460 is an industrial-grade cast aluminum or electroless-nickel enclosure that includes a local display, which has all the power, digital, and analog inputs for operating the system. This allows for a simple installation process for most applications.
Options are available for stand-alone and system configuration.
Installation
Over-Belt Conveyor
MCT460 sensors are mounted 200-450 mm (8-18 in) above the conveyor, ideally with continuous product flow.
Augers & Screw Conveyors
Installing the MCT460 on top of augers and screw conveyors allows for a measurement of the flow of material being conveyed by the flights of a screw. The MCT460 is installed offset to the side of the central shaft while the influence of the flights passing the unit are eliminated by the instrument’s software.
Bins and Chutes
Sight glass windows, such as Sapphire can be used for continuous flow of products against the window. Additionally, the snorkel sampler (sold separately) can be used to measure free-falling powders/granules in chutes.
- IR Temp Sensor: Enables simultaneous product temperature measurement.
- Snorkel Sampler: Designed to measure free falling powders/granules in chutes.
- Cal Check Standard: Used to verify sensor stability over time and transfer calibrations between sensors.
- Air Cooling: Vortex cooler attached to the sensor for high-temp applications.
- Product Loss Sensor: Enables measurements when the product flow is discontinuous or there are frequent lulls in the production stream.
