5.2 Pressure Measurement

The % full scale (FS) statements for Standard accuracy and Premier precision are only applicable
if there is a regular zero correction by the IDOS instrument.
Ranges: Gauge and Differential Operation (g/d),
Sealed Gauge (sg), Absolute (a)
+/- psi: 0.36 (+/- mbar: 25)
+/- psi: 1, 3, 5, 10 (+/- mbar: 70, 200, 350, 700)
psi: -15 to [15 or 30]
(bar: -1 to [1 or 2])
psi: -15 to [50, 100, 150, or 300]
(bar: -1 to [3.5, 7, 10, or 20])
psi: 500, 1000, 1500, 2000, 3000
(bar: 35, 70, 100, 135, 200)
psi: 5 (mbar: 350)
psi: 30 (bar: 2)
psi: 100, 300 (bar: 7, 20)
psi: 5000, 10000 (bar: 350, 700)
a. Standard accuracy is for 32 ... 122°F (0 ... 50°C);
Stability: 1 year
b. Premier precision is for 65 ... 82°F (18 ... 28°C);
Stability: ≤ 10 psi (700 mbar) = 0.02% of reading/Year
Stability: > 10 psi (700 mbar) = 0.01% of reading/Year
Premier precision for 41 ... 113°F (5 ... 45°C):
≤ 10 psi (700 mbar): 0.075% FS
> 10 psi (700 mbar): 0.014% FS
Notes
Reference port media: Non-corrosive, dry gas.
+ Port media: Non-corrosive, non-conductive liquid or Non-corrosive, dry gas.
