On-site calibration services
Maximizing process uptime while reducing risks and safeguarding compliancy
and costly decontamination can be
avoided.
Calibration requires time. Ideally, caliA
flowmeter
that is not measuring properly
can cause many problems. For example,
in a custody-transfer application,
even the smallest error can cost an operator
millions of dollars a year. And though
calibration may not be the biggest or most
important task on the to-do list of a chemical
plant, it can have a big effect throughout
the plant. Outsourced to experts,
calibration positively affects production,
compliance and the risk of quality or safety
deviations.
Flowmeters are often removed from
systems for the purpose of calibration and
sent to a calibration laboratory. The commonly
held belief is that the necessary calibration
accuracy can be guaranteed only
under laboratory conditions. However, this
is only partially true. Flowmeters and many
other measuring devices can also be calibrated
directly on-site. There are several
advantages to this:
* Plant availability improves as the device
is calibrated nearline or inline.
* Sources of error can be detected and
eliminated on-site, while the ability to
achieve the same result in a calibration
lab is limited. Calibration technicians onsite
can detect errors during installation
and identify blockages or contamination
in the pipes directly in the system.
* Cost savings increase due to the speed
of completion, reduced downtime and
the elimination of an inventory of replacement
parts.
* There is no need to disassemble and
ship contaminated devices, contact with
hazardous substances can be reduced,
bration runs are part of scheduled downtime,
so manufacturing is not affected.
However, experience shows that windows
for scheduled downtime get shorter and
shorter. Usually, instrumentation is handled
last. This is why calibration should
always be performed in a time-optimized
manner. On-site calibration reduces coordination
efforts, eliminating the need to
remove and transport an instrument to a
calibration facility. While it might take days
or weeks for a device to return from a calibration
lab, an on-site calibration can be
performed within hours.
With in-depth application, metrology
and measurement expertise, certified operators,
and traceable documentation,
Endress+Hauser can maximize the potential
of on-site calibration without compromising
safety or compliancy.

The Role of Ceramic Measuring Cells in Pressure
Measurement
P
ressure measurement is one of the
most common means of process
control. The technology is versatile because
it can measure level, density and
interface, and users can choose a measuring
cell material that best suits their
processes.
Ceramic is emerging as a cell material
compared to the more popular metal to
measure corrosive liquids in challenging
applications. VEGA pressure transmitters
eliminate moisture sensitivity and temperature
shock susceptibility. Developed
in accordance with SIL standards, the VEGABAR 80 family surpasses
most, if not all sensors currently found on the market, in
terms of several features.
Recently, the biggest leaps in technology have been experienced
by the ceramic measuring cell 'CERTEC' - the core technology
of VEGA's pressure sensors. Only a few suppliers have
ceramic-capacitive cells in their portfolio, and even fewer have
the know-how to manufacture these.
In principle, both metal and ceramic can be used in a majority
of applications. However, in many cases, ceramic is the better
technology because it is more stable, robust, and durable.
With an overload resistance factor of up to 200, CERTEC surpasses
other ceramic transmitters, ensuring reliability even in demanding
conditions.
* Extended Temperature Range:
CERTEC withstands temperatures up
to 266°F (130°C), eliminating the need
for specialized high-temperature versions
for sterilization processes.
* Expanded Measuring Range: Ceramic
measuring cells offer a measuring
range of only 3 psi or 25 mbar, without
electronic turndown, with an upper
measuring of 14.5 psi (100 mbar).
* Front-Flush Mounting: CERTEC is
the only ceramic measuring cell on
the market allowing front-flush mounting, ideal for abrasive
applications.
* Second Line of Defense: Critical for hazardous applications like
phosgene handling, this feature prevents leakage into terminal
compartments.
The VEGABAR 80 series offers a universal housing, electronics,
and adjustment concept for all measurement methods. It facilitates
customers' day-to-day work throughout the entire lifecycle
of an instrument for pressure
and level.
