Based on diode array technology, the Perten DA 7440 SD NIR process sensor measures multiple parameters in all types of fried/baked snack foods; it does not require recalibration between batches and product changeovers. The unit collects all wavelengths simultaneously and averages multiple full-spectrum readings every second for the measurement of moisture, fat, salt and seasonings. The sensor has no moving optical components and is housed in a stainless steel IP69K case. It integrates into SCADA systems and provides a range of communication options.
