Sanitary Compact Refractometer PR-23-AC

Vaisala K-PATENTS® Sanitary Compact Refractometer PR-23-AC

The Sanitary Compact Refractometer PR-23-AC provides accurate means for measuring Brix and liquid concentration in hygienic installations and in small pipe line sizes of 2.5 inch and smaller.

The PR-23-AC sensor is installed in the pipe bend. It is angle mounted in the outer corner of the pipe bend directly or through a flow cell, a Sanitary clamp or a Varivent® connection. This way the best flow conditions and self-cleaning effect can be achieved.

The measurement range covers 0-100 Brix. The accuracy is ± 0.1 Brix, and the measurement is automatically temperature compensated. Low and high concentration alarms can be configured. Because of the digital sensing technology, even large amounts of suspended solids, bubbles or color changes do not affect the measurement or the accuracy.

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 and Vaisala's documented procedure.

Features
Universal calibration of each sensor: all sensors are freely interchangeable.
Full measurement range Refractive Index (nD) 1.3200 – 1.5300, which corresponds to 0-100 Brix.
Meets 3A Sanitary Standard and tested for CIP cleanability according to EHEDG.
Dual connectivity: one transmitter can operate two sensors. A second sensor can be easily integrated later.
Completely digital system: particles and bubbles do not affect operation or accuracy.
Ethernet connection and remote panel for data logging and remote operation.
Effective heat transfer and isolation using Teflon® and ceramics in the sensor provide safe operation also in higher process temperatures (max. 130 °C/266 °F).
Fast process temperature measurement by built-in Pt1000 and automatic temperature compensation.
Easy on-site instrument verification within users's own quality assurance system with standard Refractive Index liquids.
