Black Steel Pressure Gauge

Design 

GB/T1226-2001 & EN837-1

 Dial Sizes

2'', 2½", 3'', 4'', 4½", 6''& 8'' 

50, 63, 75, 100, 115, 160, 200mm

Accuracy

2'', 2½"& 3'': ± 1.6% of span

4'', 4½", 6''& 8'': ± 1.6% of span 

Ranges

Vacuum/Compound to 200 psi

Pressure from /15 to 0/15,000 psi- 2½", 3'', 4'', 4½"

Pressure from 0/10 to 0/20,000 psi - 6'', 8''& 10''

Or other equivalent units of pressure or vacuum

Working pressure

2'', 2½"& 3'': Steady: ¾ scale value

Fluctuating: ⅔ full-scale value
Short time: full-scale value

4", 4½" & 6": Steady: full-scale value
Fluctuating: 0.9x full-scale value
Short time: 1.3x full-scale value

Operating temperature : -40°C to +70°C

 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.
