The unique and innovative K-Patents Sanitary compact refractometer PR-43-AC system consists of a compact 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-AC refractometer is designed to meet the needs of hygienic installations in small pipe line sizes of 2.5 inch and smaller. The PR-43-AC refractometer is installed in the pipe bend. It is angle mounted in the outer corner of the pipe bend directly or through a flow cell with a Sanitary clamp or a Varivent® connection. This way the best flow conditions and self-cleaning effect can be achieved. 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.
The introduction of a unique new Process Refractometer Technology Platform Four (4) brings improved levels of performance and a choice of user interfaces that fits best for various needs of applications.
Platform four also emphasizes the ongoing shift toward the use of Ethernet, and the concept of software Apps that add significant new possibilities to combine, refine and use measurement data in various industrial control and automation applications. The 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 the Ethernet connection. Every PR-43-A Refractometer also provides an mA output signal for control purposes.
The Sanitary refractometer PR-43-A is factory-calibrated to measure Brix and temperature in standard units. Each refractometer has identical calibration. For this reason, the refractometers can be freely interchanged without optical recalibration or parameter changes. The refractometer does not require any recalibration or regular maintenance. Furthermore, the calibration of each refractometer can be verified using standard refractive index liquids and a built-in verification procedure.
The Multichannel user interface MI provides the highest level of industrial computing, intelligence and sophisticated features as well as environmental protection.
