Sanitary Flush Mounted Refractometer PR-43-APT

The unique and innovative Vaisala K-PATENTS® Sanitary flush mounted refractometer PR-43-APT system consists of a flush mounted refractometer and a graphical user interface. The refractometer is a stand-alone device capable of operating independently. It has a measurement range of 0 to 100 Brix and it provides an Ethernet or 4–20 mA output signal proportional to the temperature-compensated Brix value for real-time process control. Different user interface options range from a rugged, multichannel, industrial computer to a compact light-weight and a web-based version, and allow the user to select the most preferred way to access and use the refractometer measurement and diagnostics data.

The PR-43-APT refractometer is designed to meet the needs of hygienic installations in vessels and cookers and in higher temperatures up to 150°C (300°F). The flush mounted refractometer allows the use of scrapers and mixers. The refractometer can also be installed through a steam jacket. The PR-43-APP refractometer is installed through an APV Tank bottom flange. The user interface of the refractometer can be installed locally in the field, remotely in the control room or in both locations by connecting several user interfaces in a network.

 

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.
Sanitary 3-A approved to meet the highest hygiene requirements of food production.
Withstands CIP and SIP processes and cleaning and rinsing of facilities.
Completely digital system: particles and bubbles do not affect operation or accuracy.
Patented CORE-optics: no drift, no re-calibration, no mechanical adjustments.
PR-43-A Refractometer has a built-in web server with an instrument homepage. The homepage allows for configuring, monitoring, verifying and diagnosing the refractometer via an Ethernet connection.
Effective heat transfer and isolation using Teflon® and ceramics in the refractometer provide safe operation also in higher process temperatures (max. 150 °C/300 °F).
Fast process temperature measurement by built-in Pt1000 and automatic temperature compensation.
Easy on-site instrument verification within users’ own quality assurance system and standard Refractive Index liquids.
