GALAXY Model G2330 Differential Pressure Gauge Range 15-0-15 Inch

GALAXY Model G2330 Differential Pressure Gauge Range 15-0-15 Inch

Series G2000 GALAXY Differential Pressure Gauges are Widely Utilized For Measuring Pressure of Fan And Blowing Machine, resistance of Filter, Wind Speed, Furnace Pressure, Differential Pressure Of Pore Plate,The Pressure of drum water level, Liquid Amplifier And Hydraulic Pressure System. Meantime,They Are Used To Control The Automatic Valve And Specific Value Of Air-Producer Gas In Combustion And They Are Used To Test Blood Pressure And Respiratory Pressure In Medical Health Care Equipment. There Are More Than 81 Models To Suit Your Needs Precisely.The Key Components Adopt Import Materi


  • Ambient Temperature –   -21 ~140 -6 ~60
  • Rated Pressure -20 inHg~30 inHg (-68~103KPa)
  • Overpressure – Protective rubber stopper will be blown out if rated pressure is up to about 50.8 inHg (172KPa)
  • Process Connections – 1/8″ female NPT duplicate high and low pressure taps – one pair side and one pair back
  • Housing – Die cast aluminum case and bezel,With acrylic cover,Exterior finish is coated gray to withstand 168 Hour Salt Spray Corrosion Test
  • Accuracy – ±2% of full span at 70???(21??????(±3% on -0, and ±4% on -00)
  • Range -20 inHg~38 inHg (-68KPa~130KPa)(Special Specification also can be ordered.)
