Base pressure ranges
- 0 to 2 bar (0 to 30 psi) absolute
- 0 to 3.5 bar (0 to 50 psi) absolute
Calibrated ranges
- Barometric: Up to 1.3 bar (18 psi) with minimum span of 350 mbar (5 psi)
- 低压:2条(30 psi)与最低span of 0.5 bar (7 psi)

There are two levels of performance specification:
- Standard
- Improved
Specifications include combined effects of non-linearity, hysteresis, repeatability and temperature errors over the compensated temperature range and calibrated pressure range.
Long term stabilityStandard: ±0.02% FS/annum max. Improved: ±0.01% FS/annum max. (±0.005% FS typical) Note: Unless otherwise specified, specifications are at the reference conditions of 25°C (77°F) ±5°C (±9°F)
Orientation (g) sensitivityLess than 0.05 mbar/g
