Sizes: 2 1/2”, 4” & 6” (63, 100 and 160 mm)

Accuracy class

      2 1/2”: ± 2 1/2% of span (ASME B40.100 Grade A)

      4” & 6”: ± 1.0% of span (ASME B40.100 Grade 1A)

Ranges:

      Vacuum / Compound to 200 psi (16 bar)

      Pressure from 0/15 (1 bar) to 0/15,000 psi (1000 bar) - 2½” , 4”

      Pressure from 0/10 (0.6 bar) to 0/20,000 psi (1600 bar) - 6” or other equivalent units of pressure or vacuum

Working pressure

2 1/2”:

      Steady: 3/4 full-scale value

      Fluctuating: 2/3 full-scale value

      Short time: full-scale value

4” & 6”:

      Steady: full-scale value

      Fluctuating: 0.9x full-scale value

      Short time: 1.3x full-scale value

Operating temperature

Ambient:

      -40°F to +140°F (-40°C to +60°C) - dry

      -4°F to +140°F (-20°C to +60°C) - glycerine-flled

      -40°F to +140°F (-40°C to +60°C) - silicone-flled

Medium:

      +392°F (+200°C) maximum - dry

      +212°F (+100°C) maximum - liquid-flled

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