Product Details

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.
Contamination protection
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.
