Application Note

“Change is inevitable.

Change is constant.”

-- Benjamin Disraeli

Life stays true to this famous

quote, and so does our

continual evolution as a supply

chain partner within the

Endress+Hauser Group of

companies. In addition to

performing our duties as a

North American production

center with association to local

E+H sales centers, we continue

to support our valued ISI and

Wedgewood Analytical partners

on a global scale.

Wedgewood Technology,

“Tech Times”, and ISI’s

“Sense”.

This first edition is part of a

plan that will bring many more

to come. The contents will

certainly be driven by current

events and production center

messages, but more importantly

it’s to be driven by what you

want to hear.

We look forward to serving all

of our stakeholders and invite

feedback of any kind at any

time.

This newsletter is written and

focused for the later.

The main goals of this quarterly

bulletin by e-mail are: (1) to be

more open and proactive with

our communication and, (2) to

bring analytical products,

services and knowledge into a

better understanding with our

customers.

The naming of our newsletter,

“TechSens”, was based on the

winning contest submission

from Toum Adem in our

administration department. It

combines and pays tribute to

the previous newsletters of

Dear Valued Customer:

Since the merger between Innovative

Sensors Inc. (ISI) and Wedgewood

Technology Inc. to become Wedgewood

Analytical Inc. in 2003, there have been

major changes to the combined

organization:

• the consolidation of operations

• the realignment of former sales channels

• and the relocation into a state of the art

facility in Anaheim

Throughout all the changes one constant

remained: Our dedication to you, the

customer!

As Wedgewood Analytical we have been

able to offer you the strength of the small

company, the competence of a core

business – Product Center for liquid

analytical measuring solutions - and

subsidiary with direct relationship to our

headquarters, Endress+Hauser Conducta

GmbH, in Gerlingen, Germany. Within

the renaming we will be integrated into

the Endress+Hauser Group, a private

owned family business. Their worldwide

presence and financial power will provide

us with needed support and access to

more resources within the

Endress+Hauser Group like Research &

Development and Logistics.

Starting in 2008 we have the opportunity

to maintain and build upon the unique

strengths that made each legacy company

an industry leader, while recognizing the

association to our parent organization. To

indicate this strategic alignment our new

and final name becomes Endress+Hauser

Conducta Inc. effective January 1, 2008.

For our OEM and Label customers we still

maintain ISI and Wedgewood Analytical as

well known and established brand names

within the market.

Please update your databases with the new

company name; our mailing address, phone

and fax numbers and banking information

have not changed.

The Endress+Hauser Conducta Inc.

Newsletter will inform you on a quarterly

basis about our activities and news at

Anaheim, useful Sales and Service

information and best practices for different

industries as well. Your comments and

feedback to our newsletter are very

welcome and highly appreciated!

Have a successful and prosperous year

2008. Good selling!

Wedgewood Analytical announces name change

One measure of a successful company is its’

commitment to quality and a quality

management system. Here at Anaheim

Production Center we have been very busy

with pushing that commitment and in

verifying results of that commitment. One

method of verification has been audits by

third parties, and we have had several

during the last year.

We have successfully passed an ATEX audit

for our explosion proof hardware and our

management system. We have gone

through four different FM audits, a CSA

audit, and again we have passed all of these

audits with no major findings and several

with no findings at all.

The big one for APC Anaheim was our ISO

Surveillance in December which was really

a test of our Management System and

commitment here at Anaheim. We were

successful in passsing this audit with no

major findings and only one minor finding

documented.

Our Auditor had some encouraging things

to say regarding Anaheim Productions:

"Good focus on customer requirements and

employee knowledge of their processes”,

were noted as strengths during the audit. It

is the opinion of the auditor that top

management is very committed to ensure

the Quality Management System continues

to be improved and maintained.

We are always striving to maintain and

improve our systems, this is a major benefit

to Anaheim and to our Customers around

the world.

Globally, Endress+Hauser has tended to

focus analytical products on a relatively

narrow range of industries. This is certainly

true in North America where Water and

BioPharma has dominated the

Endress+Hauser Conducta Inc. focus. In

particular, the optical (WA) products and to

some extent EChem products (pH,

Conductivity, etc…), have had limited

exposure outside of the traditional core

industries. This presents excellent

expanded growth opportunities.

For example, why should optical products

be limited to the BioPharma and Beverage

Markets when there is potential in other

industries? Optical products can be used for

many diverse applications such as heat

exchanger leakage monitoring or

controlling water concentration in Ethanol.

The same applies to EChem. Industrial

Waste Water, for example, is everywhere,

and equipment tends to be less price

sensitive compared with Muni and

Drinking Water Markets. MRO

(Maintenance and Replacement) business is

all over the place if we just look for it!

Our local representatives and direct sales

personnel are catching on quickly and are

already finding new and exciting

applications. Venturing into new industries

and applications will not only increase

analytical sales, but also helps to sell other

products! The next time you are at a

customer, try to get a tour of their lab. See

what type of technologies they are using to

verify field instrumentation or processes.

You may be surprised.

No matter what happens with the global,

political and economic landscape, the

pressure for operating cleaner plants with

fewer resources is not going to diminish

any time soon.

Last year, Endress+Hauser Conducta grew

faster than our major competitor. Imagine

what we can do if we branch out!!!

If you have questions about a specific

product, industry, or application, please do

not hesitate to contact Anaheim. We look

forward to your feedback and questions.

Application Note - To optimize the

control of a centrifuge for the removal

of solids, a solids monitor is needed to

measure both the inlet load and outlet

clarity.

Major pharmaceutical companies require

control of centrifuge to ensure clarity of

product after solids removal.

Many pharmaceutical processes start with

fermentation of solid organisms like yeast

or bacteria. After fermentation, the product

is extracted from the organisms and during

that process, the liquids and solids are

separated using a centrifuge.

During centrifugation of the mixture the

solids from the influent liquid build up in

the centrifuge bowl. The build up continues

until the bowl is full. At this point, further

separation is impossible with the removal of

the solids from the centrifuge.

Application challenges

Two methods are used to control clarity of

the centrifuge discharge.

Manual: periodically, or when the

centrifuge is full of solids, a discharge is

initiated to clear the bowl of solids. This

method does not provide a good quality

clarified stream and can put an undue load

on further clarification and filtration

equipment downstream.

Timed: While the centrifuge is in operation,

the bowl is regularly discharged on a timed

basis.

This is the most widely used method of

keeping the centrifuge clear but does lead

to loss of liquid and/or product in the solids

stream. To minimize the loss of liquid,

a short, rather than a full, discharge cycle is

employed. In many cases, however, a short

cycle does not completely clear the bowl.

Solids steadily build up and efficiency of the

centrifuge is affected.

Solution

By using online measurement both on the

in- and outlet of the centrifuge an

automated discharge operation can be

obtained for higher product yield and

minimized product loss. Typically the solids

level will be high in the beginning of

the solids removal and then fading

out during the end of the batch.

Using a Wedgewood Analytical OUSAF12

solids monitor measuring and controlling

the inlet solids/liquid mixture to the

centrifuge a constant feed can be obtained

and overloading of the bowl can be

prevented. Measuring the clarity of the

Centrate with a Wedgewood Analytical

solids monitor with extended range will not

only provide the plant with continuous data

for controlling the discharge of the

centrifuge but also with continuous quality

monitoring of the process liquid. On the

outlet of the centrifuge small air bubbles

will be formed in the process liquid. To

prevent these bubbles from interfering with

measurement a constant pressure valve is

recommended.

Instrument description

All Wedgewood Analytical in-line monitors

can be SIP/CIP in-line. The sensors are all

made in a Ultra-hygienic resilient stainless

steel flow cell design available with material

finish of 16µinch (0.4µm) Ra, in sizes from

¼” up to 4” tri-clamp and withstand up to

2900 psi (200 bar) depending upon

process connection.

Available with explosion proof design for

both FM and ATEX classification.

Measurement range for the standard solids

monitor typically starts at 0.5% solids. The

exact measurement range depends upon

the application. For the outlet the extended

range version will cover as low as 20 ppm.
