PM200 Pressure Measurement Modules

Pressure measurement modules for the Fluke Calibration 2271A industrial pressure calibrator to extend your pressure range or improve your measurements.  Install up to two pressure modules in the 2271A chassis at one time, mixing and matching module classes and 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; 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.

The 2271A can operate in gauge, absolute, or tare mode, just select a corresponding module:
• Absolute Mode:  An absolute pressure measurement is made in relation to a perfect vacuum. A value of 0 represents a perfect vacuum. Certain ranges of PMMs are intrinsically absolute mode measurement modules, designated in their model number by having an ‘A’ at the beginning of the range designation section of the model number (for example, PM200-A200K). In addition, an inherently gauge mode module (represented by a ‘G’ at the beginning of the range designation section of the model number) can be used to measure absolute pressure if combined with a Barometric Reference Module.
• Gauge Mode:  A gauge pressure measurement is made in relation to atmospheric measurement. A value of 0 represents a pressure measurement taken at atmospheric pressure. Certain ranges of PMMs are inherently gauge mode measurement modules, designated in their model number by having a ‘G’ or ‘BG’ at the beginning of the range designation section (for example, PM200- G400K). A ‘BG’ designation means that the PMM is a bi-directional gauge and thus has the ability to measure both positive and negative gauge (also referred to as vacuum) pressures. In addition, certain intrinsically absolute modules have a built-in barometer, allowing the modules to measure absolute, gauge, and negative gauge pressures.
• Tare Mode: When the user initiates Tare mode, the Product zeros out the current pressure reading. This allows an intrinsically absolute measurement module to be used to measure gauge mode measurements when not equipped with an internal barometer. Only use this method when atmospheric pressure is sufficiently stable.

With the PM200 pressure measurement modules being economically priced, you can purchase backup modules to make sure you are never down for calibration.
