iPR-Series
Your eye in
the pipe!
Inline Process Refractometers (iPR) from SCHMIDT+HAENSCH have
been used successfully in a wide range of process monitoring appli-
cations for more than 35 years.
Our iPRs continuously measure the refractive index and instantly
determine the concentration of dissolved solids in solution and/or
the mixing proportion of binary or quasi-binary liquid mixtures.
The measurement is independent of turbidity, colour and absorption
as well as viscosity.
Over 35 years of experience and optimization, we have designed
technical solutions for various demanding applications and chal -
lenging process conditions. S+H IPRs perform with unmatched
reliability, resolution and precision by using only highest quality
components and manufacturing standards. Technological highlights of iPR measuring heads
• Measurement in less than 1 second
•
Compact units with integrated electronics in the IP69K housing
(integrated or remote display optional)
• Temperature measurement within the sapphire prism ensuring
the fastest and most precise temperature reading resulting in
drift free temperature compensated measuring values
• Stated precisions are valid within the whole temperature range
• LED light source (589nm), extrem. long lifetime (100,000 hours)
Due to the unique technology implemented, the iPR light source
does not have to be exchanged or recalibrated during the entire
life time of the instrument
• Measuring sensors meet the hygienic requirements of the food
and pharmaceutical industries and tolerate temperatures up to
150°C***
• Temperature compensation for individual products
(e.g. Brix, Oechsle, Glycol, H
2O2)
• User configurable digital switches (1 A)
• Galvanic isolated 4 - 20 mA outputs*
• Internal desiccant bag increasing the life span of electrical and
optical components
• Electronic moisture sensor within the measuring head
•
Process connections with VariVent (Tuchenhagen), TriClamp, APV,
or in-line housing for small volumes
• Known SCHMIDT+HAENSCH quality „Made in Germany“

Smart heads for
smart solutions
iPR inline sensors can be used as a stand-alone solution with inte-
grated display or connected to a PLC.
Using the integrated digital switches (up to 1 A), the iPRs can
re-motely control pumps, valves as well as signals (e.g. visual,
acoustic alarm). This feature allows a direct, real-time process con-
trol and simple automations (e.g. simple dosage systems) without
an additional PLC.
The iPR measuring heads can be combined with various process
sensors such as O
2, CO 2, pH, turbidity or conductivity to an intelli-
gent sensing station.
To be resistant against most chemicals, wetted parts of our smart
heads are made of stainless steel, complying with regulations in
food, beverage and pharmaceutical industries.The synthetic YAG or
sapphire prism is both mechanically stable and chemically inert to
acids, sludge and solvents. Standard CIP procedures as well as the
pipe pig use are applicable and controllable.

The iPR mesuring head can be installed in pipes, reactors, vessels,
mixing tanks, kettles, boiling pans and evaporators, using different
weld-in flanges. Preferred sealing material is Viton but special sea-
ling (gasket) materials are available on customer request. (e.g. Kalrez)
To avoid the contact of highly concentrated acids or corrosive
substances with stainless steel surface, special PTFE inline housings
for the iPR are available. The preferred process connection from
SCHMIDT+HAENSCH is the VariVent inline housing. The VariVent
connection will handle pressure up to 10 bar and is hygienic while
minimizing dead space.
The iPR is also available in an intrinsically safe version.
(ATEX Ex II 1G Ex ia IIC T4)
For processes, where the substances cause fouling on the prism
surface, a cleaning device using water, steam or solvent is available.
For processes where such additions are not allowed, a proprietary
ultra-sonic cleaning system is available.
