Appendix B. Alternative Pressure Units
This appendix contains data for the alternative pressure units.
The basic operation of the pressure transducer uses mbar for the pressure calculations.
BHGE uses the Customer Ordering Information to set the default units for the pressure
output. The default units can be: mbar, bar, or psi.
The table below shows the values to get an output in one of the alternative pressure units.
If other units are necessary, set the applicable values to agree with local conditions.
