If you are concerned about contamination from workload coming in from the field, the 2271A-N-G20M 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-N-G20M remarkably easy to learn and to use.
Wide Workload Coverage for Both the Present, and into the Future
The Fluke Calibration 2271A features pressure ranges from -97.90 kPa (-14.2 psi) gauge to 20 MPa (3000 psi), which covers the requirements of a wide range of gauges and sensors. Thanks to its modular design, the 2271A-N-G20M 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 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-N-G20M 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.
Versatile Pressure Measurement Modules
The Fluke Calibration 2271A-N-G20M 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-N-G20M 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-N-G20M; 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.
Conveniently Located Dual Test Ports and Reference Port
Dual test ports on the top of the 2271A-N-G20M 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-N-G20M 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-N-G20M 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.
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 is not 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 two-stage filtering system.
Simplifying the Maintenance of HART Pressure Transmitters with the 2271A Industrial Pressure Calibrators
HART (Highway Addressable Remote Transducer) Protocol is an open standard used globally to send and receive digital information using analog wiring between smart devices and control systems. With over 30 million1 devices installed it is the most popular protocol used in the field. HART was first available in the late 1980’s, and quickly gained in popularity mainly due to its ability continue to support the older 4-20 mA analog protocol while adding the significant benefits of digital smart instrumentation.
Maintaining HART instruments is critical to product quality, production or plant efficiency and ensuring a green environmental footprint. While smart transmitters offer significantly better performance and functionality than their older analog transmitters, this comes at a cost of increased maintenance complexity. Maintaining these smart devices requires three types of equipment; sourcing equipment, measurement equipment and digital communication equipment. Using all these separate devices can make the maintenance time consuming and difficult. The Fluke Calibration 2271A Industrial Pressure Calibrator combines all three of these types of equipment into a single bench instrument with built-in routines that can automate and streamline the maintenance of these transmitters.
Automating the Calibration of Analog Output Pressure Transmitters using the 2271A Industrial Pressure Calibrator
Pressure transmitters are used in a variety of different applications, many of them mission critical, such as determining the flow of fluids through a pipeline or ensuring process integrity in a process plant. Therefore, process professionals must test and calibrate these pressure transmitters regularly.
Automation is a useful tool to improve the reproducibility and efficiency of your calibrations. By using the built-in tools available with the 2271A Industrial Pressure Calibrator, you can automate your pressure calibrations quickly and easily without needing specialized support software on a PC.
Cardinal Point Calibration of Pressure Dial Gauges using the Fluke 2271A Industrial Pressure Calibrator
