Operating Pressure Range

Differential Ranges

Wet/Dry
Uni-directional or bi-directional 70 mbar to 35 bar (1 to 500 psi)
Wet/Wet
Uni-directional or bi-directional 350 mbar to 35 bar (5 to 500 psi)
Line pressure: 70 bar max (1000 psi)

Barometric Ranges

Barometric ranges are available with a minimum  span of 350 mbar (5.1 psi)

Non Zero Based Ranges

Non zero based ranges are available. Contact
GE to discuss your requirements

Over Pressure

• 10 × FS for ranges up to 150 mbar (2 psi)

• 6 × FS for ranges up to 700 mbar (10 psi)

• 2 × FS for barometric ranges

• 4 × FS for all other ranges (up to 200 bar for ranges ≤70 bar and up to  1200 bar for ranges >70 bar) For differential versions the negative side must notexceed the positive side by more than:

• 6 × FS for ranges up to 150 mbar (2 psi)

• 4 × FS for ranges up to 700 mbar (10 psi)

• 2 × FS for all other ranges up to a maximum of 15 bar (200 psi)

Containment Pressure

Gauge, Sealed Gauge, Absolute and Differential (+ve port):

• 6 × FS for ranges up to 70 bar (1000 psi) (200 bar (2,900 psi) maximum)

• 6 × FS for ranges above 70 bar (1000 psi) (1200 bar (17,000 psi) maximum)

Differential (-ve port) must not exceed positive port by more than 4 × FS (15 bar (200 psi) maximum)

Supply and Outputs

Isolated/Configurable

(Option 8)

Any pressure signal output configurations will be available, subject to the following limitations:

• Minimum span: 2 V

• Maximum span: 20 V

• Output limits: ±10 V

• Maximum zero offset: ≤ span

Reverse output response to pressure is available.The output will continue to respond to 110% FS. i.e. if a 0 to 10 V output is specified, the output will continue to increase proportionally to applied pressure until at least 11 V. Current consumption is <20 mA @ 7 Vdc supply, reducing to <5 mA @ 32 Vdc supply. On startup <100 mA drawn for 10 ms typically.

Example

Power-Up Time

mV, Voltage and current versions: 10 ms

Isolated/configurable version: 500 ms

Shunt Calibration

Shunt Calibration provides customer accessible connections which, when  shorted together, cause a shift in output of 80% FS in order to simulate  applied pressure. It is fitted to the mV and Isolated/Configurable versions as  standard. It is not available with a DIN electrical connector (Option 7).

-20 to +80 °C (-4 to 176 °F): ±1.5% FS TEB
-40 to +80 °C (-40 to 176 °F):: ±2.25% FS TEB
-40 to +125 °C (-40 to 257 °F): ±2.25% FS TEB

Improved and Premium Accuracy performance:
-10 to +50 °C (-14 to +122 °F): ±0.5% FS TEB
-20 to +80 °C (-4 to 176 °F): ±1.0% FS TEB
-40 to +80 °C (-40 to 176 °F): ±1.5% FS TEB
