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.
Dual test ports on top of the 2271A
let you easily mount two devices
under test.
Conveniently located
dual test ports and
reference port
Dual test ports on the top of
the 2271A let you easily mount
two devices under test (DUTs).
You can potentially double your
throughput without spending
time searching for fittings and
tees. The vertical test ports let
you easily connect analog dial
gauges without the need for
additional test stands or manifolds. Two test port types are
supported, the standard HC20
or the P3000 test port. Both
types of test ports enable you to
make hand tight connections to
traditional NPT, BSP, or metric
pressure fittings. The HC20 test
port includes easy grip features
and integral support for M20
connections, whereas the P3000
style test port provides backwards compatibility for users of
Fluke Calibration P3000 deadweight testers or P5500 pressure
comparators.
A reference port is also
located on top of the 2271A for
applications that require an
atmospheric reference.
Safety features protect
operators and instruments
Each measurement module, as
well as the main chassis, has
pressure relief valves to protect
the instrument and its operators
from accidental overpressure.
The 2271A has been designed
using Sound Engineering Practices (SEP). With the internal
relief valves, user-settable pressure limits, and emergency abort
button, safety is the highest
priority.
Preventing contamination
If your workload includes devices
that contain different substances
like water, oil and gas, you
could be at risk for contamination—something getting into your
system that isn’t supposed to be
there. Contamination can clog
a calibrator’s valves, wear out
its parts, and make it difficult to
maintain pressure. If the contamination gets into the sensor,
it can actually change the calibrator’s behavior and throw off
your readings. If contamination
is a concern to you, order the
optional Contamination Prevention System (CPS) to help keep
the calibrator’s valves clean and
free from debris.
The CPS provides an unprecedented level of protection by
maintaining uni-directional
flow away from the controller, a
gravity sump system, and a twostage filtering system.
The Contamination Prevention System helps keep the valves on the 2271A clean
and free from debris.
Automate with COMPASS®
software for improved consistency and throughput
Fluke Calibration COMPASS for
Pressure software is designed
specifically for pressure calibration. It enables you to automate
the 2271A and run complete
pressure calibration sequences
on single or multiple devices
under test. COMPASS software
removes the unknowns often
associated with getting automated systems online. The
2271A also features a full remote
interface that enables you to
use it with custom software or
other data acquisition equipment. Details about the interface
are provided in the 2271A User
Manual.

Control turndown10:1 ( T y pica l )
Low control point1 kPa (0.15 psi) absolute
Control turndown is defined as the relationship between the provided supply pressure and the appropriate supply pressure for the range. For
example, a unit with a 7 MPa (1000 psi) and 700 kPa range (100 psi) with a supply pressure of 7.7 MPa (1100 psi) provides control precision
of 0.001 % range because 7 MPa is 10 times greater than 700 kPa. A system with ranges of 20 MPa (3000 psi) and 700 kPa (100 psi) with
supply pressure of 22 MPa (3300 psi) will have 0.001 % range control precision on the 20 MPa range but only 0.003 % control precision on
the 700 kPa range. Control precision of 0.001 % on the low range can be achieved by reducing the supply pressure.

Notes
• Gauge mode modules (PM200-GXXX or PM200-BGXXX) with ranges of 100 kPa (15 psi) or greater will support absolute mode measurement
when used with a Barometric Reference Module.
• For temperatures from 15 °C to 18 °C and 28 °C to 35 °C, add 0.003 % FS/°C.
• Uncertainty for gauge mode modules assumes routine zeroing. Uncertainty for absolute-mode modules includes 1-year zero stability.
This specification can be reduced to 0.05 % FS if the PM200 module is zeroed on a continuing basis to remove the 1-year zero stability
component.
• Instrumental measurement uncertainty for gauge mode modules used in absolute mode by addition of a barometric reference module is
calculated as the uncertainty of the gauge mode module plus the uncertainty of the Barometric Reference Module.
