High Pressure Equipment has added the full line of ASTRAGAUGE high pressure gauges, ROTASEAL high pressure swivels and high pressure Gauge Snubbers to their product family. ASTRAGAUGE has established a reputation for producing highly accurate and reliable bourdon-tube style gauges for pressures up to 150,000 psi. Wall or Flush Mounting Bottom or Back Connected 6" Diameter Black-on-White Dial All "Wetted" Parts 316 SS Accuracy - 1/2 of 1% Ascending Pressure or 3/4 of 1% for 150,000 psi 316 SS Multiturn (10 turns) Bourdon Element (Ni-Span "C" for 150,000 PSI) Turret Type Heavy Duty Sealed Aluminum Case Oxygen, Gas, & Water Service PSI: Kg/Cm2; Megapascals; Bars Polycarbonate Front Window ACCURACY The standard accuracy is 1/2 of 1% pressure or 3/4 of 1% for 150,000 psi. All gauges are calibrated against NIST traceable dead weight testers accurate to 1/10 of 1% or against a certified master gauge. Gauges are checked at a minimum of five (5) points. ELEMENT Of specially cold drawn and cold formed 316 SS. This multiturn (10 turns) helical Bourdon tube gives longer life and provides better accuracy. It is used in all ranges to 100,000 PSI. Ni-Span "C" is used for 150,000 PSI. Element has mechanically sealed end to permit cleaning when required (as for oxygen service). No soldered or welded joints. Available in 14 ranges as shown in table. PRESSURE TEST All gauges are "over-pressurized" to 130% of the rated pressure (except for 150,000 which is proof tested at 180,000 PSI) and cycled to full pressure prior to calibrating.
