A process NIR sensor installed directly above conveyors, mixers, or pipelines to monitor product composition in real time. It continuously measures moisture, fat, protein, and ash, enabling producers to optimize yield, reduce waste, and maintain product specifications throughout production.
Reliable, Accurate, Real-Time Process NIR
The DA7440 is a state-of-the-art on-line diode array NIR sensor designed to monitor products directly above conveyors, mixers, or pipelines. It provides real-time, non-destructive measurements of moisture, fat, protein, ash, sugar, fiber, and more, allowing producers to optimize processes, reduce waste, and ensure product specifications are consistently met.
Unlike traditional single-point sensors, the DA7440 captures a broad NIR spectrum using advanced diode array technology, delivering highly stable and precise results even when products vary in height, color, or temperature. Its rugged industrial design ensures continuous operation in demanding environments, while its modular options – including General Purpose, Sanitary Design, and Cooled versions – make it adaptable across industries.
Why it matters?
Real-time visibility into product composition means tighter process control, reduced energy costs, and fewer off-spec products. The DA7440 enables operators to react immediately to changes in raw materials or production conditions, safeguarding efficiency and product quality.
