2 Inline Refractometer - An Overview
D32IB002EN-D 7
2 Inline Refractometer - An Overview
L-Rix 5000/5100/5200 is an optical inline refracto-
meter for the determination of the refractive index
(RI) in liquids based on Snell’s law of refraction. It
can be immersed directly in the production liquid. It
continuously displays the refractive index (or con-
centrations) at process temperature allowing 24-
hour production control.
The process liquid flows past the sensor. The refrac-
tive index and temperature are measured simulta-
neously and displayed on the screen.
The inline refractive index measurement can be
used as a real-time predictive tool for the final con-
centration, whereby a quick and accurate response
is needed to optimize production.
The robust stainless steel construction of L-Rix
5000/5100/5200 meets all requirements of the pro-
cess environment and is fully CIP/SIP capable.
L-Rix 5000/5100/5200 has integrated self-
diagnosis.
The L-Rix Inline Refractometers are available as:
• L-Rix 5100/5200 Sensor
• L-Rix 5000 Transmitter
(=L-Rix 5100 Sensor + Pico 3000 Analog)
Features and Benefits:
• Maintenance free
• Never requires adjustment
• Long-life LED
• Hygienic design
• Full range sugar scale instrument
• No influence of potential stray lights
• Laboratory comparable refractive index mea-
surement
• Full CIP/SIP capability, reactivating quickly after
a brief time-out interval for cleaning
• Install and forget simplicity
• Compact and rugged design for industrial dura-
bility
• Longevity by hermetical sealing of optical com-
ponents
• Fulfills the NAMUR recommendation NE 107
(self-monitoring and diagnosis)
2.1 Measuring Principle
The L-Rix inline sensor determines the refractive in-
dex of liquids based on the critical angle measure-
ment as shown below. The refractive index is a
direct measure of the concentration. The measuring
prism serves as the interface between the L-Rix and
the sample liquid. The light source illuminates onto
the boundary layer between the prism and sample
liquid. Depending on the angle, some light rays will
be totally reflected, others only partially, with the
majority of the light refracted into the liquid. A CMOS
array detects the reflected light and measures the
critical angle. This angle is used to determine the re-
fractive index (specified as nD) and calculate the
concentration.

4.2.5 Prism Wash System
The L-Rix 5000/5100/5200 is appropriate for stan-
dard cleaning procedure according to the specifica-
tions:
In case L-Rix 5000/5100/5200 is installed in process
flows without any regular cleaning procedures, de-
posits could build-up on the prism surface and dis-
turb the measurement (abnormal high
concentrations and upward concentration drift). The
prism wash system is an accessory to solve the
coating problem.
For a perfect cleaning the distance between the
wash nozzle and the prism must be correct. There-
fore 3 different standard systems are available ac-
cording to the pipe diameter:
VARINLINE®Prism Wash System DN 65 or 2.5"
VARINLINE®Prism Wash System DN 80 or 3"

4.2.6 Deflector
The deflector will be installed opposite the
L-Rix 5000/5100/5200 and will deflect the flow to-
wards the prism for a self cleaning effect.
For a perfect cleaning the distance between the de-
flector and the prism must be correct. Therefore 4
different standard systems are available according
to the pipe diameter:
VARINLINE®Deflector DN 40 or 1.5"
VARINLINE®Deflector DN 65 or 2.5"
VARINLINE®Deflector DN 80 or 3"
VARINLINE®Deflector DN 100 or 4"
4.3 Electrical Wiring
TIP The L-Rix 5000 Transmitter Varivent N already
includes a Pico 3000 Version Analog. So L-Rix 5000
can not be used in combination with any other Pico
3000 version, the Pico RC nor with mPDS 5. There-
fore some parts of this chapter do not refer to the
L-Rix 5000 Transmitter.
Recommendations:
• Only use shielded cables with double insulation.
Ground the shield of the CAN cable on both
sides (mPDS 5/Pico 3000 RC and sensor side)
and make sure that there is no potential differ-
ence between the sensor and the evaluation
unit.
• Check the polarity when lengthening the cable.
• Use a screwdriver (0.4 x 2.5 mm) to install the
cables in the plugs.

4.3.2 Wiring the Sensor and mPDS 5 or
Pico 3000
All sensors communicate with the mPDS 5 or Pico
3000 RC via a CANopen bus network. The mPDS 5
or Pico 3000 RC is the CAN-master, all sensors are
slaves.

Fig. 18: Detailed view of the terminals of the sensor
All sensors have 2 CAN-interfaces. One is used for
the connection to the Pico RC or to the mPDS 5 and
the other one is used for the terminating resistor or
an additional sensor in the CAN-network. It does not
matter which one is used as CAN IN and CAN OUT.
A CAN-network wiring of more than one sensor can
be done simply without cable stubs.
The CAN-bus needs a 120 Ωterminating resistor at
one CAN-interface. To build up a network with more
sensors, the terminating resistor at CAN OUT must
be removed so that the next sensor can be connect-
ed at CAN OUT. If several sensors of the same type
are connected to one mPDS 5, unique addresses
must be selected.
