In-line infrared °Brix sensor
0 - 100 x ±0.02 °Brix, -5-85°C, IP66 | in-tek Brix Bellingham + Stanley

The in-tek IR Series of on-line instrumentation comprise a single state-of-the-art sensor module and a self contained, water tight Sensor Control Module. Unlike traditional infrared spectrophotometers that use transmitted light, the adopted technique of Attenuated Total Reflection (ATR) requires source penetration of just a few microns to obtain accurate absorption results, allowing consolidation of all optical components in to a single stainless steel sanitary 3-A housing for direct mounting to the product line using industry standard Varinline® valve body assemblies.

On-line mounting eliminates difficult to clean bypass lines and negates the need for high maintenance pumps commonly associated with this type of measurement. Pre-determined narrow band-pass interference filters are critical to differentiate the sensor type within the series by matching the energy source to the absorption model of the chemical or product under test. The Sensor Control Module provides a simple user interface as well as connectivity to plant controllers or computers via Ethernet connection, with other industrial interface types such as multiple analogue 4-20mA current loops, EtherNet and Profibus available as optional extras.
