PM600 Pressure Measurement Modules

PM600 Pressure Measurement Modules PM600 Pressure Measurement Modules

For 6270A Pressure Controller/Calibrator

Key features:

  • Fluke Calibration Quartz Reference Pressure Transducer (Q-RPT) technology provides precise measurement with long term stability
  • 0.01% reading measurement uncertainty from 30% to 100% of the modules’ span allows for extremely wide workload coverage
  • Onboard barometer included with absolute mode pressure modules, allowing them to be used in both absolute and gauge mode

Performance specifications

The performance specifications describe the complete instrumental uncertainty of the Product. The specifications include all relevant error components (linearity, hysteresis, repeatability, resolution, reference standard measurement uncertainty, 1-year drift, and temperature effects). The specifications are provided at a level of confidence of 95 %, k=2, normally distributed. Precision uncertainty includes linearity, hysteresis, repeatability, resolution, and temperature effects.

PM600 Modules measurement specifications

Specifications are valid from 15 °C to 35 °C.

Notes

  1. For PM600s absolute mode modules used in absolute mode, root sum square (RSS) with 0.007 % of FS (reduced to k=1 by square root of 3).
formula
  1. ATM is any atmospheric pressure from 70 kPa to 110 kPa (10 psi to 16 psi).
  2. For absolute ranges used in gauge mode there is an additional uncertainty of ±7 Pa for dynamic barometric compensation. When combined with other uncertainties this changes the threshold uncertainty for the PM600-A100K to 0.008 % Span and for the PM600-A200K to 0.004 % Span.
  3. These modules can be used as a barometric reference module.
