Fluke Calibration 2271A Industrial Pressure Calibrator
Wide workload coverage for the present and the future
The 2271A features pressure ranges from -100 kPa to 20 MPa (-15 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, swapping modules in and out according to your workload. 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. The Technical Note is available for download on the flukecal.com website. As with all Fluke Calibration instruments, these specifications are conservative, complete and dependable.
Versatile pressure measurement modules
The 2271A uses PM200 and PM500 Pressure Measurement Modules that let you set up a system that matches your needs for accuracy and value:
| Good: PM200 Pressure Measurement Modules | Better: PM500 Pressure Measurement Modules |

Install up to two pressure modules in the 2271A chassis at one time, mixing and matching module classes and 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.
