To avoid any mistake, it is necessary to anticipate

the detection section passes through the prism, hits the sample

Build-Up Prevention —Introducing tips, solutions, and proven strategies accumulated over many years ofexperience to prevent build-up.

There is a risk for the measuring instrument of a production line that the sample (liquid)

which flows through the pipes may adhere to the sensor section.

Moreover, there are cases where it is more difficult to clean off build-up on measuring

instruments that have been inserted in the main production line than on instruments notinstalled in the main line.The following sections will explain build-up prevention tips,

solutions, and strategies for ATAGO's in-line refractometers.

ATAGO has examples of proven strategies to prevent years of build-up fromaccumulating. As an example of our many records of proven strategies, we will introduce
feedback from some of our customers who have installed the ultrasonic cleaner, US-α.

Various Sample Inlets(Fittings for Coupling with Piping System)

Sugar Refinery

Auto Parts Company

Sugar Syrup

Surface Treatment AgentsThis customer experienced operational errors from the accumulation oflime calcium (used to remove impurities of raw sugar) deposits on thesensor section of their process refractometer. Therefore, they installed theultrasonic cleaner, US-α. The customer confirmed that there wasabsolutely no build-up once the pipeline was cleaned, and after 20 days
had passed it was still in pristine condition.
Occasionally, the customer performs some maintenance such as cleaning
with hot water and gently wiping it off just in case, but even now, they are
not experiencing any issues with measurement values.
They had a refractometer made by another manufacturer which they
periodically removed from the pipeline and performed cleaning. By
purchasing an ATAGO in-line refractometer along with the US-α, cleanings
were reduced, making the process easy and hassle-free.

This customer experienced a phenomenon in which their measurement
values increased due to surface treatment agents adhering to the sensor
section of their process refractometer. The process refractometer was
attached to a pipe that was in a high, hard to reach location, but removal
was necessary to perform cleaning every single time there was build-up.
By using the ultrasonic cleaner, US-α, build-up no longer occurs andsince there is no need to perform cleaning, work efficiency increased.

Food Company (e.g. Powdered Milk)

Chemical Company

Powdered Milk

DMF (Dimethylformamide)

The purpose of a gelling agent is to stabilize the finished coating byapplying it on the paper. This customer confirmed that throughout 32
continuous hours of operating the manufacturing line, gelling agent
build-up on the sensor section would occur every 5 to 7 hours. Due to thegelling agent's properties, build-up was prone to occur, and the customer
fretted over whether or not management with a refractometer was reallyappropriate for their application. It was at that time the customer found out
about the ultrasonic cleaner, US-α, and demoed it. Once manufacturing
begins, the process cannot be stopped, so the implementation of the US-α
has been tremendously helpful in eliminating the occurrence of build-up.

The production line is operated for about 10 days in a month andproduces 38 tons of powdered milk at one time. The concentrate's
concentration is measured with a process refractometer, but it must be
removed and wiped clean every 6 to 7 hours for the CIP process whensevere build-up occurs, and once a month for routine cleaning. Alkali usedin the CIP process eliminates acids, but calcium and magnesium remain.
Through the implementation of the ultrasonic cleaner, US-α, even if
cleaning is not done frequently, measurement values are correctly
displayed, and the customer is fully utilizing the convenience andusefulness of the US-α.
DMF is a solvent used in acrylic fiber synthesis. Up to now, concentration
control required that the unit be cleaned once every 30 minutes, but intests using our the ultrasonic cleaner, US-α, the instrument was able
to measuredly stably for 10 consecutive hours without cleaning, improving
factory efficiency.

useful and convenient feature. Alarm output can be configured for
maximum and minimum values of management ranges for
products that are up to standards in a manufacturing process that
has incorporated an in-line refractometer, or for when a few
seconds of unacceptable measurement values are continuously
measured. Using a relay driver, it is possible to detect and regulate
the occurrence of abnormal values through measures such as
turning on the alarm LED light, or sending input to a sequencer.

Stay a Step Ahead of Danger with
In-line Process Refractometer.
Dimensions (unit of length: mm)

This premium model features lab-grade accuracy across the full range of refractive index, Brix, or user-defined concentration scale. Data can be transmitted to a PLC for system automation.
This model can be installed in the pipe lines of refill tanks, cleaning solution tanks, dilution, mixing, and blending tanks of manufacturing plants that produce liquid products such as thefood and medicine industries, as well as those used in all kinds of industrial applications. This makes the unit capable of continuously monitoring items such as the refractive index, Brix,
concentration and moisture, and mixture ratio of a variety of liquids. It has been enhanced with a wider than ever Brix measurement range of 0.00 to 100.00% and an accuracy of ± 0.05%.

The materials in contact with the solution are made out of
durable SUS316L, and the sample stage has been madefully flat, resulting in a unit that's highly resistant to build-up.

A variety of output methods means defective products will
never slip through undetected. Recorder output (4-20mA)
and RS-232C output can be set-up and linked with an
external device for automatic control.

Capable of measurement at temperatures between -15 to

In-line Refractometer Terminology
 What is VARIVENT ® ? 
The VARIVENT ® valves contribute to hygienic and fully cleanable process systems.
The wetted parts of In-line Refractometers may be customized to work with VARIVENT ® components.
PRM series and CM series fittings that meet VARIVENT standards are also available.
* VARIVENT ® is a registered trademark of GEA Tuchenhagen.

Devices tested and confirmed
compatible
HMS Industrial Networks
Anybus Communicator What is PROFIBUS? PROFIBUS is a communication protocol for fieldbus, industrial computer network
between the field device and its controller in factory automation applications. PROFIBUS
is standardized under such standards as IEC 61158/61784 and EN50170. The PRM
and CM In-line Refractometers may become PROFIBUS-compatible by the use of an
adapter connected to the RS-232C port.

 What is SUS316? 
SUS316 is a type of enhanced stainless steel that contains chromium (Cr) and nickel(Ni). Molybdenum (Mo) is added, giving it superior corrosion and pitting resistance than
SUS304. It has excellent corrosion resistance to a variety of materials, from seawater toall kinds of other mediums.

 What is SUS316L? 
SUS316L is a material with a carbon (C) amount below 0.03%, in contrast to SUS316, which has a carbon
amount below 0.08%. Further differences are the amount of Ni contained in SUS316 is 10 to 14%, whereas
SUS316L contains 12 to 15%. Therefore, SUS316L is favored over SUS316 for its corrosion resistance that
contains superb work hardening (cold forming) and intergranular corrosion resistant properties.

 What is COP (Clean Out of Place)? 
COP is a method of cleaning wherein the machinery installed in the production equipment are removed,
disassembled and cleaned. It is used for cleaning machinery and parts with complex structures and components.
Machinery that is simple to disassemble and reassemble, and easily cleaned is highly demanded in regards tocleanliness.

 What is CIP (Clean in Place)? 
CIP is a system wherein the production equipment are efficiently and safely automatically cleaned without being
disassembled. The machinery isn't simply washed; it's a method of cleaning that also involves the controlling andinhibiting microorganisms.

 What is SIP (Sterilization in Place)? 
SIP is a system wherein the production equipment are sterilized (bacteria are automatically eradicated) without
being disassembled. Below are some examples of sterilization methods:• Physical sterilization through heat (pasteurization)• Filtration through a filter or membrane• Irradiation through radiation or ultraviolet rays
• Chemical sterilization through the use of pharmaceuticals
