That data showed us that even seemingly

To avoid any mistake, it is necessary to anticipate

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.

Sugar Refinery

Sugar Syrup

This 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-αTM. 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 TM,
cleanings were reduced, making the process easy and hassle-free.

 What is PROFIBUS? 

Anybus Communicator

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.

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

Auto Parts Company

Surface Treatment AgentsThis 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-αTM, build-up no longer occurs andsince there is no need to perform cleaning, work efficiency increased.

SUS304*1. It has excellent corrosion resistance to a variety of materials, from seawaterto all kinds of other mediums.
*SUS304 is a stainless steel made up of 18% chromium (Cr) and 8% nickel (Ni).

 Sample Stage Material: 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.

Paper Manufacturing Company Gelling Agent (Coating)

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 buildup on the sensor section would occur every 5 to 7 hours. Due to the gelling
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 TM , and demoed it. Once
manufacturing begins, the process cannot be stopped, so theimplementation of the US-αTM has been tremendously helpful in eliminating
the occurrence of build-up.

 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)? 

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-αTM, 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.
