Continuous process monitoring helps users to increase efficiency and reduce scrap and re-work while improving product consistency and quality. The instrument performs simultaneous measurement of parameters such as moisture, fat, sugars, protein, starch, fiber and many others. The core diode array technology provides many benefits including durability, stability, accurate measurement of moving products and the ability to track process changes.


The DA 7440 is installed and used at many agri & food production sites worldwide. These are a few examples of its applications.

  • Grain-based foods - A wide variety of food products like cookies, crackers, pasta, noodles and breakfast cereals can be measured in real-time for parameters such as moisture, fat, temperature and others. The measurements are used to control processes such as baking, frying and drying.
  • Dairy products - Measure fat, moisture, protein and more in any dairy product transported on conveyor belts or similar. Installation examples include cheese blocks.
  • Snack foods - Measure moisture, fat, and seasonings in snack food production to optimize frying and seasoning addition.
  • Tobacco - Determine moisture, nicotine and sugars in real-time in leaves as well as processed tobacco. Stable moisture readings with no need for adjustments when you switch to producing a new blend.

Information Integration

By integrating the instrument into the SCADA system, the operator can see the results in a familiar operating environment. Further, the results are available for automated controls and reporting through a central reports system. The DA 7440 offers a range of communication options including:

  • OPC DA
  • Fieldbus including Profibus DP, Modbus, etc.
  • Ethernet TCP/IP based Modbus/TCP & PROFINET
  • Analogue outputs
