General safety consideraons
The process medium may be hot or otherwise hazardous. Use shields and
protecve clothing adequate for the process medium - do not rely on avoid-
ance of contact with the process medium.
Precauons when removing a refractometer from the process line :
•Check first that the process line is depressurized and drained.
•Ensure you are clear of any possible spillage and you have a clear emer-
gency escape path.
Disposal
When wishing to dispose of an obsolete refractometer or any parts of a
refractometer, please observe local and naonal regulaons and require-
ments for the disposal of electrical and electronic equipment.

1 Introducon
The K-Patents in-line process refractometer is an instrument for measuring liquid con-
centraon in the process line. The measurement is based on the refracon of light in
the process medium, an accurate and safe way of measuring liquid concentraon. See
Chapter 7 for more informaon on the measurement principle.
The PR-43 refractometers come in three standard packages: a stand-alone refractome-
ter with Web user interface WI, a refractometer with Compact user interface CI and 1-4
refractometers with Mulchannel user interface MI.
Web user interface WI is for direct control system integraon in applicaons where no
industrial computer or monitoring display is required (see Chapters 2, 4 and 3). Com-
pact user interface provides a local or remote display with the same informaon as
WI (See Compact user interface CI manual). Mulchannel user interface provides high
performance industrial compung e.g. for mulple connecvity and wash control (see
Mulchannel user interface MI manual).

2 Refractometer connecons
The refractometer has an Ethernet connecon for digital data acquision and configu-
raon. The standard connecon cable is made with an 8-pin industrial M12 connector
in the refractometer end. For more informaon on the cables, see the manual for your
refractometer model.
2.1 Power supply
The PR-43 refractometer requires a 24 V DC power supply (allowable tolerance is
±10 %). The current consumpon of the refractometer is less than 80 mA. The power
supply should be shielded from external voltage surges.
2.2 mA output
The PR-43 refractometer can be connected with just mA output. The analogue connec-
on transmits measurement signal only.

2.3 Ethernet connecon
The Ethernet connecon enables data download from a refractometer to a computer.
Any type of computer (PC, Mac, mainframe...) with a compable network connecon
can be configured to view and download data from the refractometer. The refractome-
ter can be configured and monitored without any special soware by using a standard
web browser. Chapter 8 gives all the specificaons necessary to write a data acquision
program.
The connecon on the Split cable PR-8431 is an industrial M12 connector. If connecon
to a device that uses RJ45 is desired e.g. to connect with a laptop, Ethernet converter
cable PR-8442-001 is needed.
Figure 2.3 RJ45 network connecon
Several refractometers can be connected to the same Ethernet network. Also, the re-
fractometer has an automac funcon (known as Auto MDI/MDIX) to detect the po-
larity of the network so that the network may ulize either cross-over or straight inter-
connecng cables.
Figure 2.4 shows an example of how to connect three refractometers to an exisng LAN
with a switch.
