P820 Series (316L type double melt)_Ultra high purity pressure gauge (EP grade)

P820 Series (316L type double melt)

Service intended

P820 series are specially designed for the ultra-high purity gas distribution system used in a semiconductor, electronic, medical, biotechnology and pharmaceutical industry.

Nominal diameter 50 (2") and 63 mm (2½")
Accuracy Grade A (ASME B40.1) : 50 (2") and 63 mm (2½")
Grade B (ASME B40.1) : 50 (2") and 63 mm (2½")
Scale range -0.1 ~ 0 to 0 ~ 28 MPa
Working pressure Steady pressure : 75 % of full scale value
Fluctuating pressure : 67 % of full scale value
Working temperature Ambient : -40 ~ 65 °C
Fluid : Max. 100 °C
Temperature effect Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately
±0.4 % per 10 ℃ of full scale
