Series 9 Food Moisture Gauge
On-line Near Infrared (NIR) Moisture Sensor for Food Applications
The Series 9 NIR Food Moisture Gauge is the latest generation sensor for precise on-line measurement of moisture for use in the production of food products. Using patented non-contact technology, the gauge simultaneously measures the amount of moisture, fat/oil, protein and other key constituents present in food. It is suitable for all types of foods and processes including breakfast cereals, biscuits, crackers, crispbreads, grains, flours, nuts, spices, potato chips, snack foods, cheese processing, chocolate, coffee and many other food products. The ultra-accurate device provides continuous, dependable measurements that can be relied upon for automated process control of food process lines to improve the product quality and plant efficiency. The gauge head is constructed from hygienic, polished 316L stainless steel protected to IP67, which is easy to keep clean and is also fitted with a food-safe, tough, sapphire window with built-in air purge protection.
Degree of Bake/Brownness
The Series 9 Food Moisture Gauge can be specified with the degree of bake/brownness (DOB) option. Gauges equipped with this option have an additional measurement channel, which provides a precise, numeric value for the DOB of the food product. This eliminates the need to rely upon the operator’s perception of colour, which can be highly subjective when judged with the human eye. Measuring product colour in this way provides consistent colour standardisation and better product quality.
Multiple User Interfaces to Suit Every Situation
Several types of gauge displays are available to meet the needs of different customer requirements, all are equipped with a modern high resolution 10” colour, touch screen interface with intuitive, easy-to-use software. The simple, lower-cost Operator Terminal (OT) provides a large, easy to read display of measurement and basic gauge functions. The sophisticated Gauge Control Interface (GCI) can manage networks of multiple gauges, providing advanced configuration, data storage/trending and diagnostic functionality. An optional ruggedized, portable tablet with embedded software for managing multiple gauges with a convenient wireless connection to the gauges is also available.
Connectivity and Industrial Interfaces
The Series 9 Food Moisture Gauge can be easily incorporated into any new or existing process using its digital I/O and networking options. Up to 16 gauges can easily be networked (daisy-chained) and connected to existing PLC or SCADA systems using a number of industry-standard protocols including EthernetIP, ProfinetIO, ModbusTCP, DeviceNet and ProfibusDP. In addition, eight digital I/O and analogue outputs are also available.
Accessories and Options
A full range of accessories and options are available to simplify installation and to ensure that the system is correctly specified for dependable and reliable operation for specific applications. In the food industry, the gauge is often mounted at the exit of ovens or fryers, which means a high ambient operating temperature. This is where air or water cooling options are essential. Other options include adjustable mounting brackets, cabling options, gating for measurement of discontinuous products (such as biscuits), powder vision for measuring powders in ducts, measurement beam size, product temperature sensing and special product viewing ports.
Lowest Cost of Ownership
Long-term stability combined with industry best performance, low installation costs and no routine maintenance requirements guarantee the lowest cost of ownership over many years of service.
The Series 9 NIR Food Moisture Gauge measurement sensor works on the principle that moisture molecules within the product being measured discretely absorb a certain wavelength of infrared (IR) light. By pulsing light at these wavelengths onto the product and then capturing and measuring the reflected unabsorbed light on a light-sensitive detector, it is possible to determine exactly by how much each wavelength is being absorbed. Using advanced process algorithms and high-speed signal processing, it is possible to provide a direct moisture measurement for any given material that is presented. The measurement is unaffected by changes in process conditions such as particle size, product height temperature, ambient lighting and relative humidity changes.
The Series 9 Food Moisture Gauge can be used to accurately measure moisture in many types of materials, some examples of common applications:
- Biscuits and cookies
- Breakfast cereals
- Cheese processing
- Cocoa bean
- Tortilla and corn chips
- Dairy powders
- Extruded snacks
- Nuts, grains and seeds
- Potato chips and crisps
- Snack foods
