In-Line Process Refractometers

In-line Process refractometer sensor in spool-piece.

In-line Process refractometers are used to continuously monitor the concentrations of liquids used in pulp and paper processing, food processing, the beverage industry, chemical processing, the power industry, and primary metal processing. They monitor, report, and control process variables such as Degrees Brix, Percent Solids, Dissolved Solids, SGU, R.I. and deliver an output to external devices such as controllers, recorders, indicators, and PLC's.

In-line Process refractometers save labor costs, streamline the manufacturing process, and improve quality by detecting inconsistencies in a product early in the production phase.

Process refractometers typically consist of two main components – the sensor, which is inserted to a pipe and is exposed the the product for direct measurement. The sensor is connected by a cable to the second main component, the control module which houses the display, electronics, power supply and output connections. Both the sensor and the control module are designed for high accuracy and precise control. Their housing and cabling are often specialized for use in varying extreme conditions and very demanding environments.

The control module includes programming for a wide variety of commonly required features, capabilities, and options that can be adapted to a customer’s requirements. This microprocessor control also allows for custom programming for specialized needs.

The sensor can be supplied with a multitude of mounting and cleaning options. Cleaning options include hand cleaning systems, high pressure cleaning systems, and steam cleaning systems. Mounting adapter options include lined adapters, spool-piece adapters, sanitary connection adapters, and weld-in adapters.

Not to be confused with their distant relatives - the handheld digital or analog laboratory refractometer - today's rugged, industrial in-line process refractometers provides continuous process management for large-scale facilities giving them the ability to increase product yield, maintain consistency, and eliminate waste.
