PR21S - Inline real-time measurement in pipelines

Accurate results for automatic and continuous process control

The inline process refractometer PR21S are installed in pipelines of production facilities in order to control and regulate the concentration, mixing and fermentation processes. Thanks to the standardized connections, the measuring device can be easily installed in pipelines. The measuring chamber is made of stainless steel, the measuring prism consists of scratch-resistant and especially chemical-resistant sapphire and is designed to prevent solids from sticking.

• Determination of the refractive index directly in the line within a range of nD 1.3200–1.5200 and 0–90 %Brix

• Measurement intervals approx. 60 seconds

• Automatic temperature compensation (%Brix and freely definable for customer-specific products)

• Integrated sensor for temperature monitoring

• User-defined scale

• Stainless steel measurement chamber that meets all the requirements of the food and pharmaceutical industry, CIP capable

• Sample prisms, made of scratch-proof and chemical-resistant sapphire

• Cleaning manually or via customer process cleaning

• Easy connection with process control system or MPC via analogue outputs (0/4-20 mA)

• Display for the visual monitoring is also available

Typical applications for the PR-Series

The process refractometer is the ideal solution for the chemical, petrochemical, automotive, aviation, metal processing, food, sugar, beverage, paper industries as well as wastewater control.
