Vaisala Process Refractometer PR-23-GP/GC

For measuring Brix in the demanding cane and beet sugar refining and milling processes

Feature
• 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

Features
•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.
