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

Thang đo:

  • Vacuum / Compound to 200 psi (16 bar)
  • Pressure from 15 psi (1 bar) to 15,000 psi (1,000 bar)
  • Pressure from 15 psi (1 bar) to 10,000 psi (700 bar) – 2” size or other equivalent units of pressure or vacuum

Áp suất làm việc:

  • 2 & 2½” Steady
  • ¾ full-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

Nhiệt độ vận hành:

  • Ambient: -40°F to +140°F (-40°C to +60°C) – dry
  • -4°F to +140°F (-20°C to +60°C) – glycerine filled
  • -40°F to +140°F (-40°C to +60°C) – silicone filled
  • Medium: +140°F (+60°C) maximum

Các lỗi nhiệt nhiệt độ: 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.

Weather protection: Weather tight (NEMA 4X / IP 66)

Pressure connection:

  • Material: copper alloy
  • Lower mount (LM) or center back mount (CBM) –
