Precision Pressure Modules Offer Measurement Accuracy

Fluke Corporation has introduced the 750P Series Pressure Modules to meet the requirements of evolving pressure calibration standards and reference class accuracy pressure instrumentation. The 48 precision modules enable gage, differential, dual range, absolute, and vacuum pressure measurement with Fluke 750 and 740 series Documenting Process Calibrators and 725, 726 Multifunction Process Calibrators.

The 750P Series is designed for the different use models specified in new calibration requirements. There are 11 new modules with two times more accuracy than standard modules for applications in pharmaceuticals or custody transfers in oil and gas. For industries like nuclear and pharmaceutical that now require calibration every six months, the 750P Series offers a six-month specification that provides better accuracies between these shortened calibration cycles.

The new modules cover pressure calibrations from 0 to 1 in H20 to 10,000 psi (2.5 mBar to 690 bar) with a 0.025 percent reference uncertainty. Digital communication to calibrators eliminates errors due to poor connections and electrical interference.

Gage pressure modules have one pressure fitting and measure the pressure with respect to atmospheric pressure. Differential pressure modules have two pressure fittings and measure the difference between the applied pressure on the high fitting versus the low fitting. Each module is clearly labeled for range, overpressure and media compatibility. All modules include NPT, metric (BSP) and M20 adapters.
