Investing in Memosens saves costs
Now it's easy to calculate the savings online
It is not a contradiction to say thatinvestments help to reduce costs.
Customers of Endress+Hauser havesaved up to 50% on their maintenancecosts since the commercial launchof Memosens five years ago. Thoseinterested can now calculate thesavings to be gained from using thenon-contact sensor technology online
on Endress+Hauser's web site.

Switching from analog to digital is worth it
As of October 2009, Endress+Hauser has supplied more than 130,000
pH electrodes with Memosens. Depending on the area of application andcustomer requirements, users save between 30% and 50% of their costs
when compared to analog pH measuring points. With the new online
calculator on www.apps.endress.com/memosens, customers can now
calculate their cost savings on the basis of standard values. They can also findout at what point in time their investment will have paid for itself. A simple
calculation requires only three values: the number of measuring points, thenumber of calibrations per month and the number of replacement sensors
per year and per measuring point. If customers know their company's hourly
rates for experts and operating personnel as well as the calibration times,
the calculation can be customized further.

Customers adopt Memosens
technology as standard
Nowadays, a world without Memosens
sensors and their inductive plug-in
connection is virtually inconceivable. The
technical benefits of this sensor technology
are particularly apparent under harshprocess conditions. Customers in theprocess industry, such as Bayer, Merck andLanxess, have already adopted Memosens
as a standard in their plants.
Mr. Werske, an expert in measurement
and control technology in the chemical
production of Merck KGaA, highlights thekey benefits of Memosens: "The possibilityof simply exchanging the sensors on siteand servicing them at a central location
under ideal conditions results in quality andcost advantages which more than justify thecosts of retrofitting.“As part of their innovative calibrationand maintenance strategy, Merck relies
on predictive maintenance, with the staff
simply replacing the sensors on site withcalibrated sensors at regular intervals.

Specialists in measurement technology
then regenerate the replaced electrodes intheir own factory and make them readyfor operation in the process again. This
strategy prolongs the operating life of thesensors significantly. Experts use Memobase
software to analyze and optimize theirmeasuring systems and maintenancestrategies.

Joint effort for utilizing and enhancing
Memosens technology
Memosens has caused a stir in the industry.
Four out of five Endress+Hauser customers
are now opting to use the smart sensor
technology when fitting out new plants.
Thanks to these satisfied customers andpartnerships, the technology is on the way
to becoming an industry standard.
The first partnership agreement was signed
between Endress+Hauser and Knick.
These two manufacturers of measurement
technology are developing a joint platform
for inductive, non-contact connection
systems for the benefit of all users. Quality
and compatibility are guaranteed by
the Memosens seal of quality. Hamilton
Bonaduz is another manufacturer who issupplying Memosens sensors. This meansthat customers can now choose fromseveral suppliers of sensors and devices.

The Memosens technology
A remarkable feature of Memosens sensor
technology for analytical measuring
technology is its ease of use with
its inductive plug-in connection. Its
integrated intelligence means that data
relating to the process and the sensor
can now be saved and also put to further
use directly in the plug-in head. Thismeans that the sensors can be calibrated
centrally in a laboratory under constantand ideal conditions. Non-contact digital
signal transmission has revolutionized
pH measurement and prolonged theoperating life of the sensor by up to40%. Thanks to 100% galvanic isolation,
Memosens is resistant to environmental
influences, even under water.

Advantages of the technology• Only system on the market with perfectgalvanic isolation, inductive and noncontact transmission of data and energy• Measured values are processed in thesensor's plug-in head
• Resistant to environmental influencessuch as moisture, corrosion and salt
bridges; even possible to plug in thesystem under water• Patented bayonet lock for easy opening
and closing, without twisting the cable• Sensor operating life up to 40% longer,
few calibration cycles• No grounding pin or potential matchingnecessaryIn addition to digital pH measurement,
Memosens technology is also alreadyavailable for ORP, conductivity, oxygenand chlorine. This platform will besystematically expanded to include otherliquid analysis parameters. The future ofanalytical measuring technology belongs
to these smart, non-contact sensors.
