Linearity, hysteresis and repeatability effects are included.
Stability
For ranges 2, 3, 4, 5 and 6:
± 0.15% of URL for 5 years at 20 °C temperature change and up 7 MPa (1000 psi) of
static pressure
For ranges 0 and 1:
± 0.2% of URL for 12 months at 20 °C temperature change and up to 100 kPA (1 bar) of static
pressure
For level transmitters:
± 0.2% of URL for 12 months at 20 °C temperature change
Temperature Effect
For ranges 2, 3, 4, 5 and 6:
0.2 URL
span
URL:
± [ 0.02% URL + 0.06% span] per 20 °C (36 °F)
0.0085 URL
span < 0.2 URL:
± [ 0.023% URL + 0.045% span] per 20 °C (36 °F)
For range 1:
0.2 URL
span
URL:
± [ 0.08% URL + 0.05% span] per 20 °C (36 °F)
0.025 URL
span < 0.2 URL:
± [ 0.06% URL + 0.15% span] per 20 °C (36 °F)
For range 0:
0.2 URL
span

± [0.15% URL + 0.05% span] per 20 °C (36 °F)
0.05 URL
span < 0.2 URL:
± [ 0.1% URL + 0.3% span] per 20 °C (36 °F)
For LD303L:

O per 20 °C for 4” and DN100
17 mmH
2
O per 20 °C for 3” and DN80
Consult for other flange dimensions and fill fluid.
Static Pressure Effect
Zero error:
For ranges 2, 3, 4, 5 and 6:
± 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 transmitters:
± 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 1and 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)
Power Supply Effect
± 0.005% of calibrated span per volt
Mounting Position
Effect
Zero shift of up to 250 Pa (1 inH
2
O) which can be calibrated out.
No span effect.
Electromagnetic
Interference Effect
Approved according to IEC61326-1:2006, IEC61326-2-3:2006, IEC61000-6-4:2006, IEC61000-6-2:2005.
