Fluke Calibration

Fluke 2271A Industrial Pressure Calibrator

Model No :

Fluke 2271A

Part Code :

Please contact us for final configuration

Overview

The Fluke 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. 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.
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.

Features

- Calibrate a wide range of gauges and sensors with a single instrument
- Two levels of accuracy, 0.01% reading or 0.02% FS
- Wide measurement range from -100 kPa to 20 MPa (-15 to 3000 psi)
- Removable pressure measurement modules make it easy to change or add measurement ranges
- Integrated electrical measurement module with HART communication provides a complete solution for calibrating pressure transmitters
- Built-in dual test ports enable you to connect multiple devices under test (DUTs)
- Localized graphical user interface in choice of ten languages

Major Applications

- For calibrating a wide variety of pressure gauges and sensors
