Vaisala Process Refractometer PR-23-GP/GC
For measuring Brix in the demanding cane and beet sugar refining and milling processes
• 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.
• Completely digital system: Particles, crystals and bubbles do not affect operation or accuracy.
• CORE-optics: no drift, no re-calibration, no mechanical adjustments.
•Ethernet connection and remote panel for data-logging and remote operation.
• Process temperature range: -20°C – 150°C (-4°F – 300°F).
• Fast process temperature measurement by built-in Pt1000 and automatic temperature compensation.
Dual connectivity: one transmitter can operate two sensors. A second sensor can be easily integrated later.
• Easy on-site instrument verification within users’ own quality assurance system with standard Refractive Index liquids.
Vaisala SAFE-DRIVE Proses Refraktometresi PR-23-SD
For kraft chemical recovery applications
•SAFE-DRIVE isolation and retractor tool allows for safe and easy insertion and removal of the refractometer sensor under full process pressure. Easy-to-place and self-retaining design. Triple sealing by two lip seals and an O-ring.
•Accidental opening or closing of the isolation ball valve is prevented.
•The retractable prism wash nozzle can be safely removed for a service check.
•SAFE-DRIVE retractor protects the user from accidental spills during retraction and insertion.
•The SAFE-DRIVE sensor is very easy to install to any pipe size (2 inch…24 inch) by welding or via a spool piece (diameter 2 inch…20 inch). Can be mounted either on horizontal or vertical pipelines. Maximum static pressure is 40 bar, maximum operating pressure is 10 bar. Spool piece process connection is DIN-flange PN25/ANSI-flange 150 lbs.
•Refractive index (nD) 1.3200 – 1.5300 corresponding the full range of dry solids for a majority of applications, or 1.3600 – 1.5700 for acacia and eucalyptus hardwood black liquor at above 80% dry solids.
•The factory calibration ensures same nD measurement performance for all sensors, making them interchangeable without additional optical calibration.
•Process temperature range: -20° – 170°C (-4° – 340°F)
•Dual connectivity: one transmitter can operate two sensors independently. A second sensor can be easily integrated later.
•Completely digital system: particles and bubbles do not affect operation or accuracy.
•CORE-optics module: no drift, no re-calibration, no mechanical adjustments.
•Ethernet connection and remote panel through Internet allow for data-logging and remote operation, e.g. review instrument data and diagnostics.

In-line liquid concentration or density measurement for process control in general industry applications
•Identical refractometer calibration. For this reason, each refractometer is freely interchangeable with each other without any optical recalibration or parameter changes.
•Full range, nD = 1.3200…1.5300 corresponds to hot water…100 % by weight. Optional ranges: nD = 1.260…1.470; nD = 1.410…1.620; nD = 1.520…1.730
•Process temperature range for compact type PR-43-GC: -40°C…130°C (-40°F…266°F), for probe type PR-43-GP: -40°C…150°C (-40°F…302°F).
•Completely digital system: particles and bubbles do not affect operation or accuracy
•CORE-optics: no drift, no re-calibration, no mechanical adjustments required
