| Overpressure |
The operating FS pressure range may be exceeded by the following multiples with negligible effect on calibration:
- 8 x for ranges up to 1.5 mH2O
- 6 x for ranges above 1.5 to 3.5 mH2O
- 4 x for ranges above 3.5 mH2O (1400 mH2O max.)
|
| Pressure containment |
- 10 x for ranges up to 3.5 mH2O gauge
- 6 x for ranges above 3.5 mH2O gauge (1400 mH2O
maximum)
- 200 bar for absolute ranges
