  • 3. Pressure Measurement 30 Bar 20mAAbsolute Pressure Example, 4-20mA 0 – 30 BarGage PressureVacuum 4mA
  • 4. Pressure MeasurementAbsolute Pressure 20mAGage Pressure 0-10 bar 4mA 4mAVacuum 0 to -1 Bar 20mA
  • 5. Accuracy DifferencesFull ScaleFull Scale w/ Electrical ShiftBest Fit Straight LineTotal Error Band
  • 6. Accuracy % of Full Scale Maximum difference between an actual value and it’s indicated value by the sensor Example, 0.5% FS (full scale) 1.00+/- 0.5% Full Scale Error 0.75 0.50 0.25 0.00 -0.25 -0.50 -0.75 -1.00 0 20 40 60 80 100 80 60 40 20 0 Pressure bar
  • 7. Accuracy % of FS (full scale) w/ Electrical Shift Ex: +/-0.25% FS w/ +/-1% Electrical Shift 1.50 1.25 1.00 0.75+/- 0.25% F.S. 0.50 0.25 0.00 -0.25 -0.50 -0.75 -1.00 -1.25 -1.50 0.0 20.0 40.0 60.0 80.0 100.0 80.0 60.0 40.0 20.0 0.0 Pressure bar
  • 8. Accuracy Best Fit Strait Line A calculated accuracy consisting of Linearity, Hysteresis and Repeatability. 0.35 0.25+/- 0.15% BFSL 0.15 0.05 -0.05 -0.15 -0.25 -0.35 0.0 20.0 40.0 60.0 80.0 100.0 80.0 60.0 40.0 20.0 0.0 Pressure bar
  • 9. Accuracy Total Error Band The maximum allowable output deviation from the actual reading. TEB accounts for linearity, hysteresis, repeatability and thermal effect. 1.20 1.00 0.80 0.60+/- 1.0% TEB 0.40 0.20 0.00 -0.20 -0.40 -0.60 -0.80 -1.00 -1.20 0 20 40 60 80 100 Pressure bar run#1@32F. run#2@130F. run#3@32F. run#4@130F.

  • 15. ApplicationIrrigation System Manufacturers Used to modulate Variable Frequency Drives (VFD) for constant water pressure Saves Energy
  • 16. Application Booster Pump SystemsBooster systems increasesupplied city waterpressureTransmitters givefeedback to the VFDApplications wherebooster pumps are used: Irrigation Commercial Building water supply
  • 17. ApplicationCompressed Air Systems Pressure Transmitters used to ensure desired pressures Monitors downstream pressure, provides input to VFD to maintain setpoint Pneumatic Tools Manufacturing Facilities Industrial Vacuum Systems
  • 18. ApplicationCompressed Air Systems High accuracy 626 (0.25% Full Scale) used to ensure desired pressures in more critical applications Medical air compressors
  • 19. Application ChillersChillers produce chilled water/fluid to a heatexchanger to cool air for air conditioning.Pressure transmitters used for diagnosticsand to provide feedback to the VFD.Also available with Schraeder connection to beused with some refrigerants.

  • 20. Application “Ready mix”/Construction VehiclesRemote Indication ofHydraulic PressurePreviously had pressuregage mounted in cabwhich is quite dangerous Up to 4000 psi (626/628)
  • 21. ApplicationBoiler Manufacturers A boiler is a closed vessel where fluid is heated as it flows through combustion of fuel. Pressure Transmitters are used to monitor fluid supply lines and VFD (Variable Frequency Drive) control
  • 22. ApplicationReverse Osmosis (RO)System Manufacturers Water Purification system that removes salt from seawater Pressure Transmitters used for VFD control Also used for filter diagnostics & initial backwash
  • 23. Application Fire Pump System ManufacturersAuxiliary pump systems designed to augmentwater pressure during sprinkler systemactivation• Provides feedback to the VFD to maintain water pressureRegulations may require continuousrecording of line pressure
