• Inline, real-time refractive index, Brix or concentration measurement to monitor and control the concentration of dissolved solids in solutions, or liquids in process

• Stainless steel measuring head featuring a sapphire or YAG prism, CIP capability (pipe pigs usable)

• Continious measurement and real-time process control with analog and digital outputs, limit comparators and internal diagnostics

• Programmable scales, Brix scale temperature corrected

IPRs measure the refractive index continuously and determine thereby the concentration of dissolved solids in solution and/or the mixing proportion of binary or quasi-binary liquid mixtures.

The measurement is independent of turbidity, colour and absorption and is free of Signal drifts, granting high precision and better process control. The Brix measurement is temperature-compensated for the process stream conditions, generating reliably both high resolution and high precision.

The new generation of IPR measuring heads have high communication skills. The process sensors can visualize the measuring results as a single solution by data logger. lt can be used as fully autonomous sensor or connected directly to a supervisory process control system or to the Universal Controller.

The new generation of IPR measuring heads gives also the possibility to construct an intelligent sensor station which consists for example of several refractometers , turbidity measuring devices and CO ₂ sensors. The Universal Controller can also be used as a control desk for different other process sensors e.g. 0 ₂ , CO ₂ , pH or conductivity.

This special kind of characteristic in the communication opens valuable economy possibilities for customers, because a separate display or special configuration is not needed for each sensor.
