MCT469-SF Washdown - In-Line Sensor for Moisture Measurement

The Process Sensors MCT469-SF is intended for use in washdown settings in the food and snack food manufacturing industries. The sensors assist operators in controlling moisture and oil/fat to ensure that product criteria are met every time. The IP69 rated MCT469-SF is developed with NIR technology, which is widely used and accepted in food processing.

Process NIR Applications for Food Manufacturers

The MCT469-SF On-Line NIR Smart Sensor is utilized in food processing facilities that require an IP69 washdown rating, such as:


  • Milk powders
  • Oil-based flavorings
  • Extruded Snacks
  • Snack foods (popcorn, potato/corn chips, pretzels, pork rinds, cookies/crackers, tortillas, etc.)
  • Breakfast cereals

How It Works

Proven Technology for Washdown Food Applications

The MCT469-SF NIR analyzers are installed into important regions of a manufacturing process to continually monitor incoming raw materials or regulate manufacturing operations. To monitor moisture, oil, and other on-line measures, each option is designed to connect easily over belt conveyors, auger/screw conveyors, or bins & chutes.

The MCT469-SF scanning process is simple but reliable:

  1. The lamp’s light is routed through a 2000 rpm revolving wheel with NIR filters suited for the purpose
  2. The product being measured is illuminated with NIR light
  3. A mirror within the unit captures the light reflected off the product and focuses it onto a Peltier Cooled lead sulfide detector.
  4. The on-board “smart” circuit board compares the detector’s output to the internal reference beam. The percentage of moisture, oil, and other factors are then calculated.

Sanitary Design

The MCT469-SF has an IP69 rating, which is the industry standard for food processing equipment. The sensor housing design has no welds, removing any potential for food contamination and making it perfect for Clean-in-Place (CIP) applications.

The MCT469-SF is also impervious to high-pressure cleaning or steam jets, making it a fully washable solution for determining moisture, oil, and other food quality criteria.

System Components

The MCT469-SF is a food-grade stainless-steel enclosure with a local display that features all of the system’s power, digital, and analog inputs. Most applications can now be installed quickly and easily.

Installation Options

Over-Belt Conveyor

The MCT469-SF sensors are positioned 8–18 inches above the conveyor, ideally with continuous product flow.

Augers & Screw Conveyors

The MCT469-SF can be mounted on top of augers and screw conveyors to measure the flow of material being transported by the screw flights. The MCT469-SF is mounted offset to the side of the central shaft, and the instrument’s software eliminates the effect of passing aircraft.

Bins and Chutes

Sight glass windows, such as Sapphire, can be used for the continuous flow of products against the window.
