ASME B40.100

2½” & 4"

Accuracy class
2½”:  ±2/1/2% of span per ASME B40.100 Grade 2A)
4":     ± 1.0% of span per ASME B40.100 Grade 1A

Vacuum/compound to 200 psi (16 bar)
Pressure from 0/15 psi (1 bar) to 20,000 psi (1,600 bar) or other equivalent units of pressure or vacuum

*Note: The maximum ocean depth in which the gauge is operating at might be considered when selecting the pressure range

Working pressure
2½”:   Steady: 3/4 scale value
          Fluctuating: 2/3 Full-scale value
          Short time: Full-scale value
4”:     Steady: Full-scale value
         Fluctuating: 0.9 x full-scale value
         Short time: 1.3 x full-scale value

Operating temperature
Ambient: - 40°F to + 140°F (-20°C to + 60°C) dry
Media:Maximum +392°F (+ 200°C) dry

Temperature error
Additional error when temperature changes from reference temperature of 68° (20°C) ± 0.4% of span for every 18°F (10°C) rising or falling.
