PM200 Pressure Measurement Modules

PM200 Pressure Measurement ModulesPM200 Pressure Measurement Modules


For 2271A Industrial Pressure Calibrator and 6270A Pressure Controller/Calibrator

Key features:

  • 0.02% FS specification makes it ideal for calibrating or testing pressure dial gauges, lower accuracy transmitters, or pressure switches
  • Rugged silicon pressure sensor design allows for faster control
  • Economic price point helps facility the purchase of backup modules, making sure you are never down for calibration

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.

PM200 Modules

Specifications are valid from 18 °C to 28 °C. For temperatures from 15 °C to 18 °C and 28 °C to 35 °C, add 0.003% FS/°C.

Notes

  1. PM200 gauge mode modules support absolute mode measurement when used with a barometric reference module. Instrumental uncertainty for gauge mode modules used in absolute mode by addition of a barometric reference module is calculated as the uncertainty of the gauge mode module root sum squared with the uncertainty of the barometric reference module. Uncertainty for gauge mode assumes routine zeroing which is default operating mode when used in a chassis. Uncertainty for absolute mode modules includes 1-year zero stability. This specification can be reduced to 0.05 % FS if the PM200 module is zeroed on a continuing basis to remove the 1-year zero stability component.
  2. This module can be used as a barometric reference module.
