Static Pressure
Effect
Zero error:
For ranges 2, 3, 4 and 5: ± 0.033% of URL per 7MPa (1000 psi)
For range 1: ± 0.05% of URL per 1.7 MPa (250 psi)
For range 0: ± 0.1% of URL per 0.5 MPa (5 bar)
For Level model: ± 0.1% of URL per 3.5 MPa (500 psi)
The zero error is a systematic error that can be eliminated by calibrating at the operating static pressure.
Span error:
For ranges 2, 3, 4, 5 and 6: correctable to ± 0.2% of reading per 7MPa (1000 psi)
For range 1 and level transmitters: correctable to ± 0.2% of reading per 3.5 MPa (500 psi)
For range 0: correctable to ± 0.2% of reading per 0.5 MPa (5 bar) (70 psi)
Power Supply
Effect
± 0.005% of calibrated span per volt
Mounting Position
Effect
