150000psi high pressure gauges

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.

Accuracy

The standard accuracy is 1/2 of 1%. 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. 

Movement 

For best accuracy and smoothness of operation, a special bronze movement is used. Zero adjustment is achieved by means of a micro pointer gear arrangement. The range can be field adjusted from the outside of the case, provided a suitable calibration standard is available. 

Dial 

PSI/MPA dual dial is standard scale. Special orders are available. (i.e. KgCm2, Bar, MPA) 

Socket Adapter and Special Openings 

We can offer (on special order) sockets for (7,500 - 30,000) 1/2" NPT or 1/2" NPS (straight) but caution that at the higher pressures it will be difficult to achieve leak free joints. 

Safety 

The case is the turret type and of heat treated high tensile aluminum having a heavy section between the viewer and the Bourdon element, thus providing safety in case of element failure. The standard dial face is an easily removable polycarbonate plastic, sealed with a Tetra-Seal gasket. A light, plastic, frangible diaphragm back sealed to the case by an “O” ring, provides safety in case of element failure, proven by tests to be the safest possible design. 

Options 

Maximum Pressure Indicator, Liquid Filled, Astratact (high-low contacts) and Special Order Dial. 

Pressure Connections 

Standard is 1/4" high pressure (1/4" HP, F250C, H F-4) available in bottom or back connected in all ranges up to 100,000 PSI. For the higher pressure ranges (e.g. 50,000 to 150,000 PSI) we can offer our 2V connection suitable for 3/8" OD x 1/16" ID tubing. 

1/4" High Pressure 

3/8" High Pressure 

Stainless Steel Panel Mounted Pressure Gauges 

Stainless steel, panel mounted pressure gauges are available from stock for immediate delivery. These gauges are standard with a High Pressure 1/4" O.D. tubing connection (HF4). These coned and threaded connections are machined directly into the bottom inlet of the gauges. Adapters for other size connections are available from stock.

HiP stainless steel gauges have a solid front separating the dial face from the pressure tube in order to provide maximum safety. Bourdon tube and socket are 316 S.S. and include a safety blowout back and laminated safety glass. Gauges may be used intermittently to 100 percent of dial reading.

Accuracy on 5,000 psi and 10,000 psi models is 1/2% of full scale reading. Accuracy on 20,000 psi through 30,000 psi models is 1% of full scale reading.

Gauge Snubber 

The gauge snubber is a device used to “smooth” out the pressure fluctuations created by reciprocating pumps commonly used to develop the high pressures required for waterjet cutting. This “smoothing” action provides more accurate pressure indication and extends the life and calibration of the pressure gauge. Gauge Snubber is rated for 60,000 psi service and uses a 1/4” HP connection (3/8" and 9/16" HP available). 

Rotaseal 

The ROTASEAL was developed for use in the waterjet cutting industry where a rotating member is required to conduct the high pressure water safely and without leaks.

The ROTASEAL is offered in two configurations - right angle or straight through. ROTASEALS are available for pressures to 60,000 PSI and flow rates to 15 GPM (at lower pressures).
