6270A Pressure Controller / Calibrator
Calibrate a wide range of pressure gauges and sensors with this reliable, easy-to-maintain instrument
- Unsurpassed rangeability in one pressure controller/calibrator: install up to five measurement modules with uncertainty as good as 0.01% reading from 30% to 100% of the modules' span.
- Configure for today's requirements, expand later as your needs change and grow. Add modules to increase the pressure range or accuracy in seconds, without needing to return the instrument to the factory.
- Optional contamination prevention system helps you avoid risk of contaminating your pressure standard when calibrating hydraulic devices.
The Fluke Calibration 6270A Pressure Controller / Calibrator is a robust, reliable solution that lets you dramatically simplify the task of pneumatic pressure calibration. Thanks to its modular design, it is so flexible that it can be configured to meet a wide variety of needs and budgets, and expanded to cover a very broad workload, at purchase or later as your needs change and grow.
The 6270A is ideal for pressure sensor manufacturers who want to avoid downtime on the production line and need a pressure source that performs both quickly and accurately. Its modular design makes it easy to maintain; its high speed control and accuracy over a wide range give them the throughput they require.
Managers and technicians in calibration laboratories and instrument shops appreciate the 6270A calibrator’s control precision and accuracy over a wide pressure range, which enables them to calibrate a wide range of devices with a single calibrator. They also like the contamination prevention option that provides an important safeguard against that pervasive hazard.
The 6270A is easy to learn and use, thanks to a graphical user interface and an intuitive hardware design.
Calibrate a wide workload—quickly, accurately, dependably
The 6270A features pressure ranges from low differential pressure to 20 MPa (3000 psi), which covers the requirements of most gauges and sensors. Two levels of accuracy, 0.02 % FS or 0.01 % reading, let you balance your need for accuracy with the limits of your budget.
Thanks to its modular design, the 6270A is flexible enough that you can install modules with different accuracy classes within the same chassis. You can buy the highest level of accuracy for the pressure ranges that require it and a lower, more economical level of accuracy where applicable.
The 6270A’s 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. As with all Fluke Calibration instruments, these specifications are conservative, complete, and dependable.
Cutting edge technology and performance
The PM600 Pressure Measurement Modules use the Fluke Calibration Quartz Reference Pressure Transducer (Q-RPT) technology to provide 0.01 % reading measurement uncertainty from 30 % to 100 % of the modules span. The modules are available in 14 different ranges including modules that are inherently absolute mode and gauge mode. The absolute mode modules include an onboard barometer. The barometer provides dynamic compensation of changes in atmospheric pressure, allowing for the modules usage in both absolute and gauge mode. The wide percent of reading capability combined with its ability to measure both gauge and absolute gives the PM600 Pressure Measurement Module the ability to cover an extremely wide workload.
The PM200 Pressure Measurement Modules use a highly characterized silicon pressure sensor to provide an economical method of making accurate pressure measurements. The 0.02 % 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.
Wide rangeability assures wide workload coverage
The standard pressure control module can handle a wide range of pressures. A flexible range control module is also available if you need to handle an even wider range.
The 6270A features pulsewidth- modulated control, a proven technology that enables it to deliver wide rangeability, the ratio of the maximum to the minimum specified measured value at which the instrument performs correctly. A wide rangeability is what enables you to calibrate a wide workload.
Safety features protect operators and instruments
Each measurement and control module, as well as the main chassis, has pressure relief valves to protect the instrument and its operators from accidental overpressure. The 6270A has been designed using Sound Engineering Practices (SEP). With the internal relief valves, user-setable 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 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 for you, order the optional 6270A Contamination Prevention System to help keep the calibrator’s valves clean and free from debris.
Modular configuration gives you almost unlimited flexibility
Install up to five pressure modules in a single 6270A chassis, mixing and matching module types and ranges to get the combination that best suits your needs. Buy just what you need to calibrate the pressure ranges in your current workload. Add modules later as your workload grows and changes.
Modules snap in and out quickly and easily; just slide each one into a specially-designed track and tighten the knob until you hear it click into place. The click tells you that the module is safely in place; a special “anti-torque” guard on the knob prevents over-tightening. You never have to wonder if you tightened it too much or not enough.
Modules are installed and uninstalled through the front of the chassis. You can easily install and remove both the measurement modules and the control module from the chassis, even if the 6270A is installed in a rack mount.
Each module uses an enhanced face-seal design that has been leak tested to pressures that are 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.
Create an automated piston gauge system
So easy to maintain, you can do it in house
We designed the 6270A to be easy to maintain, making your cost of ownership very reasonable. We publish a Service and Calibration Manual with detailed instructions on how to replace valves and components. An onboard screen capture routine can be used for troubleshooting help.
Control and measurement modules are separate, allowing for quick and easy repair. Just pull out the module and replace it; no auto-tuning required. You can change the pressure ranges just as easily by installing a new module and possibly changing the supply pressure. No need to send the 6270A back to the factory.
The modules can be calibrated either in the chassis or outside the chassis using the optional PMM Calibration Kit. Once calibrated, you can use them in any 6270A chassis without impacting the uncertainty of your measurements. Modules can be removed and replaced, easily; no specialized tools required.
Every component in the system is designed for simple, modular replacement, from the front panel to the rear pressure connections.
Internal components, like the main CPU, are designed to be easily replaced. The pressure connectors on the back of the 6270A are made from anodized aluminum, a robust material that stands up well to normal usage. However, if threads are stripped or there is galling from metal connectors sliding against it, you can easily remove the block without having to open the chassis. Simply remove the screws holding it in place and pull it out. The block does not have any items attached to it, so replacement simple and low cost.
The removable rear manifold makes it easy to remove the 6270A from a rack-mounted system. Simply vent the test and supply ports and disconnect the connection manifold from the back of the chassis. You won’t need to question which pressure line is the supply port and which one is the test port; they stay connected to the manifold, and the manifold can only be connected one way. Three types of manifolds—NPT, BSP, and 7/16- 20—are available to meet the needs of different geographic regions. The isolation valves on the main manifolds are easily removed from the top of the 6270A chassis.
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 6270A and run complete pressure calibration sequences on single or multiple devices under test (DUTs). COMPASS software removes the unknowns often associated with getting automated systems online.
The 6270A 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 6270A User Manual.

|1 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) will provide 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.|

|1 1-year specification is instrumental measurement uncertainty that includes linearity, hysteresis, resolution, reference uncertainty, 1-year stability, and temperature effects from 15 to 35 °C. The uncertainties are provided at 95% confidence, k=2, normally distributed.|
|2 Gauge mode uncertainty is the greater of the relative uncertainty and the threshold uncertainty. For absolute ranges used in gauge mode there is an additional uncertainty of ± 7 Pa for dynamic barometric compensation. When combined with other uncertainties this changes the threshold uncertainty for the PM600-A100K to 0.008% Span and for the PM600-A200K to 0.004% Span.|

2 1 year specification is Instrumental Measurement Uncertainty that includes linearity, hysteresis, resolution, reference uncertainty, 1 year stability, and temperature effects from 18 to 28°C. The uncertainties are provided at 95% confidence, k=2, normally distributed. For temperatures from 15 °C to 18 °C and 28 °C to 35 °C, add 0.003% FS/°C.
3 Uncertainty for gauge mode modules assumes routine zeroing. Uncertainty for absolute mode modules includes one year zero stability. If routinely zeroed, uncertainty is 0.05 % FS
4 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.
