Fluke 2271A Data sheet

2271A Industrial

Pressure Calibrator

The complete pneumatic
pressure calibrator that grows
along with your workload
for wide workload coverage
now and in the future

Technical Data

The Fluke Calibration 2271A
Industrial Pressure Calibrator
provides a complete, automated
solution for calibrating a wide
variety of pressure gauges and
sensors. Thanks to its modular
design, it can be configured to
meet different needs and bud­gets, and expanded to cover a
broad workload.

The 2271A is ideal for calibra­tion laboratories starting out in
pressure calibration because it
offers wide pressure measure­ment capabilities in a single
instrument. Everything you
need for calibrating pressure is
included; just connect supply
pressure. And your investment
will stand the test of time:
as your workload grows and
changes, the 2271A can grow
and change too. Just add mea­surement modules.

The 2271A is also a great
fit for labs that currently cali­brate pressure transmitters and
gauges and want to expand

their capabilities or make their
processes more efficient. This
instrument is easy to set up and
use, so you don’t have to reserve
it for your most experienced
technicians. And it can be fully
automated so it can help your lab
run more efficiently.

If you are concerned about
contamination from workload
coming in from the field, the
2271A is a good choice for you
as well. Its optional Contamina­tion Prevention System (CPS)
provides an important safeguard
against that pervasive hazard.

A graphical user interface in
your choice of ten languages and
an intuitive menu structure, as
well as an intuitive hardware
design, make the 2271A remark­ably easy to learn and to use.

Wide workload coverage
for the present and the
future

The 2271A features pres­sure ranges from -100 kPa to
20 MPa (-15 psi to 3000 psi),
which covers the requirements
of a wide range of gauges and
sensors. Thanks to its modular
design, the 2271A enables you
to install two modules with
different measurement ranges
within the same chassis. You can
purchase modules to match your
current workload now; later,
when your workload changes
and grows, you can easily add
ranges. This flexibility enables
you to maintain your investment
in the 2271A for years to come.

A built-in electrical measure­ment module (EMM) with HART
capabilities enables you to per­form closed loop, fully automated
calibration on 4-20 mA devices
such as smart transmitters,
gauges and switches. Just set up
the 2271A and then walk away
to attend to other tasks.

The EMM supplies 24 V dc
loop power for measuring mA
and V dc. It has a built-in 250
Ohm resistor that can be toggled
on or off, eliminating the need
to have an external resistor to
enable HART communications.

The 2271A accuracy specifi­cations are provided in full and
supported by a technical note
that details its measurement
uncertainty so you know exactly
what you are getting. This
technical note is available for
download on the flukecal.com
website. As with all Fluke
Calibration instruments, these
specifications are conservative,
complete and dependable.

Install up to two pressure
modules in the 2271A
chassis at one time.

Use the 2271A to perform closed loop, fully automated calibration on
4-20 mA devices like this transmitter.

Versatile pressure
measurement modules

The 2271A uses PM200 Pressure
Measurement Modules. These
modules use a highly character­ized silicon pressure sensor to
provide an economical method
of making accurate pressure
measurements. The 0.02 % full
scale (FS) specification includes
the short-term performance of
the module (linearity, hysteresis
and repeatability) as well as
its long-term stability and the
uncertainty of the calibration
standard. Users can be confi­dent in the PM200 measurement
performance.

Install up to two pressure
modules in the 2271A chassis
at one time, mixing and match­ing module ranges to get the
combination that best suits your
needs. There is no limit to the
number of modules that can be
used with the system, allowing
you to change pressure ranges

on the fly to meet your needs.
Modules snap in and out quickly
and easily through the front of
the 2271A; just slide each into
a specially-designed track and
tighten the knob until you hear
it click into place. The click
tells you the module is safely
in place; a special anti-torque
guard on the knob prevents
over-tightening so you never
have to wonder if you tightened
it too much or not enough.

Each module uses an
enhanced face-seal design that
has been leak tested to pres­sures three times higher than
the maximum working pressure.
You don’t have to worry about a
leak in the system affecting your
ability to measure and control
pressure.
