Fluke Calibration 6270A Pressure Controller / Calibrator
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. Three levels of accuracy, 0.02 % FS, 0.01 % reading from 50% to 100 % or 0.01 % reading from 30 % to 100 %, 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
Three families of pressure measurement modules provide three levels of performance that let you set up a system that matches your needs for accuracy and value.

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 pulse-width-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.

| 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. | |
