Description
Design
ASME B40.100
Sizes
4½” (115 mm) dial size
Accuracy class
± 0.5% of span (ASME B40.100 Grade 2A)
± 1.0% of span (ASME B40.100 Grade 1A)
for 20,000 psi (1,600 bar) range and above
Temperature error
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.
