• What are the different types of pressure gauges?

  PRESSURE GAUGES Pressure Gauges Industrial and Process PGI Series ■40, 50, 63, 100, 115, and 160 mm (1 1/2, 2, 2 1/2, 4, 4 1/2 and 6 in.) dial sizes ■Accuracy in accordance with ASME, EN, and JIS ■Available with a variety of end connections, including Swagelok®tube adapters ■Center-back, lower-back, and lower mount configurations

• What is the dial size of a pressure gauge?

  Pressure gauge dial sizes range from less than 1˝ to 16˝ diameters. Generally, readability require- ments, space limitations and required gauge accuracy determine dial size. Accuracies of 0.25% or 0.5% generally have dial sizes of 41⁄ 2˝ or larger since more dial graduations are required. 5. CONNECTION SIZE

• What are the different sizes of PGI pressure gauge?

  S, B, and L 63 mm (2 1/2 in.)size PGI-63-MIP-SG S, B, and L 100 mm (4 in.)size PGI-100-MIP-SG P 115 mm (4 1/2 in.)size PGI-P-115-MIP-A Industrial and Process Pressure Gauges– PGI Series 23

• What is the maximum operating pressure for a pressure gauge?

  If pulsation is present in the process, maximum operating gauge pressure should not exceed 50% of the full-scale range. CONCLUSION To properly select a pressure gauge, consider the gauge process, range, environment, accuracy, dial size, connection and mounting requirements.
