Fluke 750P Series Pressure Modules

Overview

The Fluke 750P Series is a family of modular pressure measurement/calibration modules available in gage, absolute, differential, dual-range, high-pressure and vacuum configurations covering ranges from 0 to 1 inH2O up to 0 to 10000 psi (0 to 700 bar) depending on model. Individual module examples: gage models include 750P057 (0 to 30 psi) through 750P2000 (0 to 2000 psi); absolute models include 750PA3 (0 to 5 psia) through 750PA9 (0 to 1500 psia); differential modules span 0 to 1 inH2O up to 0 to 15 psi and higher (models 750P00 through 750P247); high-pressure models include 750P29 (0 to 3000 psi), 750P30 (0 to 5000 psi) and 750P31 (0 to 10000 psi); vacuum modules include 750PV3 (-5 psi) and 750PV4 (-15 psi). Uncertainty and performance are published per model. Typical reference uncertainties are given (for example ±0.0175% or ±0.03% or ±0.01% of full span depending on module class) and total uncertainty figures are provided for 1-year and 6-month intervals at 15-35°C; total-uncertainty guidance is also stated for wider temperature bands (0°C to +50°C, and a -10°C to 0°C condition with separate allowance). Reference uncertainty is defined as the as-left specification for 24 hours. When these reference-class modules are used with fixed-resolution products (717, 718, 719 series, 725 and 726) an additional ±1 count is added to the overall accuracy specification. Module burst ratings are specified as a multiplier of full scale (examples: 2X, 3X, 4X and up to 30X for the lowest differential ranges) to guide safe overpressure selection, and an intrinsically safe pressure module option is available within applicable ranges. Media compatibility is listed per module as Dry air or non-corrosive gasses and/or Type 316 Stainless Steel wetted materials where shown; low-side ports are N/A or Dry air as indicated by model. These modules are selected to match the required pressure span, uncertainty class, media compatibility and burst-rating for industrial pressure calibration work and for use with Fluke fixed-resolution calibrators where noted.
