Vaisala K-PATENTS Process refractometer PR-23-G is designed for measuring the liquid concentration and density in a wide range of chemicals, fibers, plastics, salts and sodium components. This model is also suited for Brix measurement of sugar solutions in harsh sugar industry conditions.
The PR-23-G masters highly accurate measuring technology in demanding process control applications where conventional density equipment may struggle due to undissolved solids or bubbles in the process stream. The instrument installs directly into the process pipe or vessel and provides a continuous 4-20 mA or digital measurement signal for real-time process control.
The refractometer system consists of a probe refractometer PR-23-GP or a compact refractometer PR-23-GC and an Indicating transmitter.
The refractometer system features dual connectivity, i.e. one transmitter can operate two sensors. A second sensor can be easily integrated later.
The measurement range covers 0-100 % by weight. The accuracy is typically ±0.1 % b.w. and the measurement is automatically temperature compensated. Low and high concentration alarms can be configured.
Each sensor is provided with a calibration certificate comparing a set of standard liquids to the actual sensor output. The calibration and accuracy can be verified on-site with the certified Refractive Index liquids.
