Fluke Calibration 2271A is a modular automated pressure calibrator designed for professional calibration of pressure gauges, pressure transmitters, pressure switches and pressure sensors. With a pressure measurement range from -100 kPa to 20 MPa (-15 psi to 3,000 psi), interchangeable PM200 and PM500 pressure measurement modules, integrated electrical measurement functions and automated pressure control, the 2271A provides a complete solution for industrial and laboratory pressure calibration. Fluke
The modular architecture is one of the key strengths of the Fluke Calibration 2271A. Two pressure measurement modules can be installed in the chassis, allowing different pressure ranges and accuracy classes to be combined in one system. As calibration requirements change, modules can be exchanged or additional ranges purchased without replacing the complete controller. PM200 modules are designed for economical industrial calibration with specifications down to 0.02% FS, while PM500 modules provide measurement uncertainty down to 0.01% of reading over significant portions of their ranges. Fluke
The 2271A also integrates an Electrical Measurement Module, or EMM, with mA and DC voltage measurement, 24 V DC loop power and HART communication. This allows pressure transmitters to be connected, powered, controlled and calibrated directly with the same system. Fully automated closed-loop calibration of 4–20 mA smart pressure transmitters can therefore be performed without requiring a separate digital multimeter, loop supply or external HART resistor. Fluke
For calibration laboratories looking to improve throughput, the 2271A can automate pressure generation, stabilization, electrical measurement and evaluation. It can also be controlled by Fluke Calibration COMPASS for Pressure software or integrated into custom automated calibration systems through Ethernet, RS232 and USB interfaces. Fluke

Fluke positions the 2271A as a complete automated system for calibrating pressure gauges and sensors, with modular measurement capabilities and electrical transmitter calibration functions in one chassis. Fluke
Ideal for Demanding Calibration Applications
The Fluke Calibration 2271A is designed for laboratories and industrial facilities that need to calibrate a broad variety of pressure instruments with repeatable automated processes.
Typical applications include:
- Calibration of analog pressure gauges
- Calibration of digital pressure gauges
- Pressure transmitter calibration
- HART pressure transmitter calibration
- 4–20 mA pressure transmitter testing
- Pressure switch testing
- Pressure sensor calibration
- Production testing
- Quality assurance
- Automated calibration stations
- Calibration laboratory applications
- Industrial maintenance
- Research and development
The system is particularly attractive for laboratories that are expanding their pressure calibration capabilities because its modular design allows the available workload to grow without replacing the complete pressure controller. Fluke
Pressure Range up to 20 MPa
The Fluke Calibration 2271A covers pressure measurement ranges from:
-100 kPa
to:
20 MPa
or approximately:
-1 bar to 200 bar.
In imperial units, Fluke specifies:
-15 psi to 3,000 psi. Fluke
The broad range makes the 2271A suitable for both relatively low pneumatic pressures and demanding industrial pressure calibration applications.
The overall working range depends on the pressure measurement modules installed in the system. This means the instrument can be configured specifically for the customer’s actual calibration workload instead of relying on one fixed sensor range.
PM200 Pressure Measurement Modules
The PM200 family provides an economical solution for many industrial pressure calibration tasks.
For most commonly used PM200 ranges, Fluke specifies:
0.02% FS.
This level of performance is particularly suitable for:
- Analog pressure gauges
- Lower-accuracy pressure transmitters
- Pressure switches
- General industrial pressure instruments
The PM200 modules use rugged silicon pressure sensing technology and are designed to provide fast and reliable pressure control. Fluke
Multiple PM200 ranges are available, extending from very low bidirectional pressures through gauge pressure ranges up to 20 MPa / 3,000 psi. Individual accuracy specifications depend on the selected module, particularly for the lowest ranges. Fluke
PM500 Pressure Measurement Modules
For more demanding calibration requirements, the Fluke Calibration 2271A also supports PM500 pressure measurement modules.
PM500 modules use highly characterized and linearized silicon pressure sensors.
For many ranges, Fluke specifies a measurement uncertainty of:
0.01% of reading
between approximately 50% and 100% of the range. Fluke
This makes PM500 modules suitable for higher-accuracy pressure transmitters, digital pressure gauges and other devices requiring better measurement performance than the standard PM200 class.
By combining PM200 and PM500 modules, a laboratory can match both accuracy and investment cost to its actual workload.
Modular Design
The modular design is one of the most important characteristics of the Fluke Calibration 2271A.
Two measurement modules can be installed in the same chassis. Modules can be selected according to pressure range and required performance, then replaced when calibration requirements change. Fluke
This provides several advantages.
A laboratory can start with only the pressure ranges it currently requires.
Additional ranges can be added later.
A module can be replaced without purchasing a new controller.
Different accuracy classes can be selected for different workloads.
The investment therefore remains adaptable as the number and type of devices under test change.
Dynamic Pressure Control
The Fluke Calibration 2271A not only measures pressure but also automatically generates and regulates it when supplied with an appropriate pneumatic pressure source.
For most ranges, Fluke specifies dynamic control precision of:
0.001% of range span.
Special low-pressure configurations have different values. The PM200-BG2.5K is specified at 0.005% of range span, while certain very low-pressure PM500 configurations are specified at 0.002% of range span. Fluke
This precise regulation enables the 2271A to establish repeatable calibration points automatically.
Control Turndown of 10:1
The typical control turndown is:
10:1. Fluke
Fluke notes that the available supply pressure is an important factor in achieving the specified control performance. To meet the control specification, the supply pressure should not be greater than approximately ten times the range of the active measurement module.
This is particularly relevant when very different pressure modules are installed in the same controller.
Fast Pressure Settling
The settling time depends on the installed module and the calibration setup.
Fluke specifies typical settling times including approximately:
20 seconds for many PM200 modules
and approximately:
30 to 45 seconds for PM500 modules depending on range. Fluke
Actual settling time can also be influenced by test volume, pressure tubing, leaks, supply pressure and vacuum performance.
Fast and repeatable pressure settling is important in automated calibration because it directly affects total calibration time.
Integrated Electrical Measurement Module
The Fluke Calibration 2271A integrates pressure and electrical calibration functions.
Its Electrical Measurement Module enables measurements required for pressure transmitter calibration without the need for several separate instruments.
The module supports electrical measurements through standard 4 mm connections and allows signals up to 30 V DC relative to chassis ground. europascal.de
The integrated concept simplifies calibration bench design and reduces setup time when pressure transmitters are regularly calibrated.
HART Pressure Transmitter Calibration
The EMM provides integrated HART communication.
It also includes an internal:
250 Ω resistor
that can be switched into the circuit when required for HART communication. Fluke
This eliminates the need for an external resistor in many HART calibration setups.
The 2271A can therefore support fully automated closed-loop calibration of smart pressure transmitters.
Pressure is generated and controlled automatically, the transmitter is supplied with loop power, its electrical signal is measured and the calibration procedure can be evaluated automatically.
24 V Loop Power
The integrated Electrical Measurement Module also provides:
24 V DC loop power.
This allows compatible two-wire pressure transmitters to be powered directly from the Fluke Calibration 2271A during calibration. Fluke
A typical transmitter calibration setup can therefore use the 2271A for:
pressure generation,
reference pressure measurement,
24 V transmitter supply,
mA measurement,
and HART communication.
This significantly reduces external instrumentation and cabling.
Dual Test Ports
The Fluke Calibration 2271A incorporates dual test ports, allowing multiple devices under test to be connected conveniently. Fluke
This can increase laboratory throughput when multiple pressure instruments need to be connected to the same pressure source.
The test-port concept is also designed to support convenient connection and removal of devices without unnecessarily complicated adapter arrangements.
Different chassis configurations are available with NPT, BSP and alternative test-port arrangements. Fluke
Pneumatic Pressure Calibration
The Fluke Calibration 2271A is a pneumatic pressure calibrator.
Fluke specifies the pressure supply medium as:
clean, dry air
or:
nitrogen.
For nitrogen, industrial grade with approximately 99.5% purity is specified. Fluke
Fluke also places limits on particulate contamination, moisture and hydrocarbon content to protect the internal pneumatic system.
A clean pneumatic supply is especially important for maintaining controller reliability and protecting the pressure measurement modules.
Optional Contamination Prevention System
Pressure instruments returning from industrial service may contain oil, moisture, particles or other contamination.
To protect the controller from contamination entering through the device under test, Fluke offers an optional Contamination Prevention System, or CPS.
The CPS uses a combination of controlled flow direction, a gravity sump and filtration to reduce the risk of contamination reaching the pressure controller. Fluke
This option can be particularly valuable in calibration laboratories handling pressure gauges and transmitters from different customer applications.
Automated Pressure Transmitter Calibration
Automation is one of the strongest capabilities of the Fluke Calibration 2271A.
Fluke describes workflows in which the calibrator automatically moves through predefined pressure points, waits for the selected dwell time, measures the transmitter output and evaluates the result against a defined tolerance. Fluke
The user can define:
- Start pressure
- End pressure
- Number of test points
- Direction of calibration
- Dwell time
- Maximum settling time
- DUT zero and full-scale values
- Pass/fail tolerance
Once started, the procedure can run in closed-loop mode with minimal operator intervention.
This helps improve consistency between calibrations while allowing laboratory personnel to perform other tasks.
COMPASS for Pressure
The Fluke Calibration 2271A can be integrated with COMPASS for Pressure software for automated calibration and test sequences.
COMPASS can support automated calibration of single or multiple devices under test and is designed specifically for pressure calibration applications. Fluke
The instrument also offers a full remote interface for integration into customer-specific software environments.
Ethernet, RS232 and USB
For automated operation, the 2271A provides:
Ethernet
RS232
and:
USB. europascal.de
These interfaces provide flexibility when integrating the controller into an existing calibration laboratory, production test system or custom software environment.
