AMETEK Crystal GaugeCal-HP<\/strong> is a powerful, portable and self-contained pressure comparator designed for professional calibration of pressure gauges, transmitters, sensors and pressure safety valves. With hydraulic pressure generation up to 15,000 psi \/ 1,000 bar \/ 100 MPa<\/strong>, the GaugeCal-HP provides a practical manual solution for high-pressure calibration in laboratories, workshops and field applications.<\/p>\n Unlike an electronic pressure calibrator, the GaugeCal-HP does not measure pressure itself. It is a precision pressure generator and comparator. A suitable reference pressure gauge, such as an AMETEK Crystal XP3i or XP2i, is connected to the comparator together with the device under test.<\/p>\n The GaugeCal-HP then generates and finely adjusts the common pressure applied to both instruments.<\/p>\n This creates a classic comparison calibration system:<\/p>\n GaugeCal-HP + Reference Pressure Gauge + Device Under Test<\/strong><\/p>\n AMETEK designed the GaugeCal-HP to provide significantly faster operation than traditional deadweight testers and many automated pressure controllers. Its portable, self-contained design makes it particularly useful for calibrating pressure gauges that would otherwise be impractical or uneconomical to calibrate using a large laboratory pressure system.<\/p>\n The GaugeCal-HP can be operated hydraulically with water or oil<\/strong>. AMETEK offers dedicated complete System G configurations for both media: the GOX system for hydraulic oil<\/strong> and the GWX system for water<\/strong>.<\/p>\n An unusual additional capability is pneumatic low-pressure generation. When operated without hydraulic fluid, the GaugeCal-HP can generate pressure up to approximately 400 inH\u2082O \/ 995 mbar<\/strong>, with fine adjustment sensitivity down to 0.01 inH\u2082O \/ 0.025 mbar<\/strong>.<\/p>\n At europascal<\/strong>, the AMETEK Crystal GaugeCal-HP can be combined with precision digital pressure references to create complete pressure comparison and calibration systems. For professional calibration and metrological traceability, visit the europascal Calibration Service<\/a>.<\/p>\n The AMETEK Crystal GaugeCal-HP<\/strong> combines high-pressure generation, portability and convenient manual operation in one pressure comparator.<\/p>\n Key advantages include:<\/p>\n The AMETEK Crystal GaugeCal-HP<\/strong> provides a maximum hydraulic pressure of:<\/p>\n 15,000 psi \/ 1,000 bar \/ 100 MPa<\/strong>.<\/p>\n This high maximum pressure allows the comparator to cover a broad range of industrial pressure calibration applications.<\/p>\n Suitable devices under test include:<\/p>\n The pressure range extends from routine hydraulic applications to demanding high-pressure calibration.<\/p>\n It is important to distinguish the AMETEK Crystal GaugeCal-HP<\/strong> from instruments such as the Crystal XP3i.<\/p>\n The GaugeCal-HP:<\/p>\n generates and adjusts pressure<\/strong>.<\/p>\n A Crystal XP3i or another suitable reference instrument:<\/p>\n measures the generated pressure<\/strong>.<\/p>\n The complete calibration setup therefore consists of:<\/p>\n Pressure Comparator \u2192 Reference + Device Under Test<\/strong><\/p>\n The reference and DUT are exposed to the same pressure.<\/p>\n Their indications can then be compared at defined calibration points.<\/p>\n This comparison principle provides a simple and highly flexible method for calibrating pressure instruments.<\/p>\n The primary application of the AMETEK Crystal GaugeCal-HP<\/strong> is hydraulic pressure generation.<\/p>\n The integrated pressure generation mechanism allows pressure to be generated manually without an external hydraulic pressure supply.<\/p>\n This makes the unit self-contained and suitable for portable use.<\/p>\n The hydraulic operating range extends to:<\/p>\n 15,000 psi \/ 1,000 bar<\/strong>.<\/p>\n All connected gauges, adapters, tubing and devices under test must be appropriately rated for the required pressure.<\/p>\n The GaugeCal-HP can be operated with:<\/p>\n water<\/strong>.<\/p>\n AMETEK offers the dedicated:<\/p>\n GWX Pump System<\/strong><\/p>\n for water applications.<\/p>\n The current AMETEK system overview specifies:<\/p>\n distilled water<\/strong><\/p>\n as the medium for the GWX configuration.<\/p>\n Water is particularly useful for applications where contamination with hydraulic oil must be avoided.<\/p>\n The GaugeCal-HP can alternatively be operated with:<\/p>\n hydraulic oil<\/strong>.<\/p>\n AMETEK offers the:<\/p>\n GOX Pump System<\/strong><\/p>\n for this purpose.<\/p>\n The current complete pressure system specification identifies:<\/p>\n Rando HDZ32<\/strong><\/p>\n as the hydraulic oil for the GOX system.<\/p>\n Oil operation is suitable for many conventional hydraulic pressure gauges, transmitters and sensors.<\/p>\n The availability of both water and oil configurations makes the AMETEK Crystal GaugeCal-HP<\/strong> suitable for different calibration environments.<\/p>\n The appropriate medium should be selected according to:<\/p>\n Cross-contamination between different pressure media should be avoided.<\/p>\n Although primarily a hydraulic high-pressure comparator, the GaugeCal-HP has an additional low-pressure capability.<\/p>\n When operated:<\/p>\n without hydraulic fluid<\/strong><\/p>\n the comparator can generate pneumatic pressure up to:<\/p>\n 400 inH\u2082O \/ 995 mbar \/ 29 inHg<\/strong>.<\/p>\n This significantly expands the possible application range.<\/p>\n The same pressure generator can therefore be used for selected low-pressure pneumatic measurements as well as high-pressure hydraulic applications.<\/p>\n During pneumatic operation, AMETEK specifies a fine adjustment sensitivity of:<\/p>\n 0.01 inH\u2082O<\/strong><\/p>\n or approximately:<\/p>\n 0.025 mbar<\/strong>.<\/p>\n This enables precise setting of low differential pressure values.<\/p>\n AMETEK specifically highlights this capability for calibration of differential pressure transmitters.<\/p>\n The AMETEK Crystal GaugeCal-HP<\/strong> can also generate vacuum.<\/p>\n AMETEK specifies a vacuum capability down to approximately:<\/p>\n -12.5 psi<\/strong><\/p>\n or:<\/p>\n -0.86 bar \/ -86.2 kPa<\/strong>.<\/p>\n This provides additional flexibility for pressure instruments that must be tested below atmospheric pressure.<\/p>\n A distinctive feature of the GaugeCal-HP is its:<\/p>\n pivoting two-port manifold<\/strong>.<\/p>\n This design makes it easier to install pressure gauges of different sizes.<\/p>\n Large analog gauges can be difficult to mount on conventional compact pressure pumps because the instrument housing can interfere with the pressure generator.<\/p>\n The pivoting manifold provides additional positioning flexibility.<\/p>\n The manifold allows the reference pressure gauge and the device under test to be connected to the same pressure system.<\/p>\n A typical configuration is:<\/p>\n Reference Gauge \u2194 GaugeCal-HP \u2194 Device Under Test<\/strong><\/p>\n Pressure generated by the comparator acts on both instruments.<\/p>\n The indication of the DUT is then compared with the value from the reference instrument.<\/p>\n AMETEK equips the GaugeCal-HP with an:<\/p>\n integral gauge-safe venting system<\/strong>.<\/p>\n This is particularly useful when calibrating mechanical pressure gauges.<\/p>\n Sudden pressure release can damage sensitive mechanical gauges or create undesirable pressure transients.<\/p>\n The controlled venting system helps protect connected instruments during pressure release.<\/p>\n Hydraulic pressure calibration inevitably involves the possibility of small amounts of test fluid being released during connection and disconnection.<\/p>\n The GaugeCal-HP incorporates a:<\/p>\n no-mess drip tray<\/strong>.<\/p>\n This helps capture test fluid and keeps the calibration work area cleaner.<\/p>\n The feature is particularly useful when multiple pressure gauges are calibrated in succession.<\/p>\n The AMETEK Crystal GaugeCal-HP<\/strong> contains an integrated fluid reservoir with a volume of approximately:<\/p>\n 176.9 cm\u00b3<\/strong>.<\/p>\n This provides the hydraulic medium required for pressure generation.<\/p>\n The piston stroke volume is approximately:<\/p>\n 13.1 cm\u00b3<\/strong>.<\/p>\n The self-contained reservoir eliminates the need for a separate external hydraulic fluid supply during normal operation.<\/p>\n The GaugeCal-HP uses AMETEK Crystal:<\/p>\n CPF pressure connections<\/strong>.<\/p>\n The installed CPF male connections have a maximum allowable working pressure of:<\/p>\n 15,000 psi \/ 1,000 bar \/ 100 MPa<\/strong>.<\/p>\n The CPF system is designed for professional high-pressure applications and simplifies connection of compatible gauges and adapters.<\/p>\n The GaugeCal-HP connection system is based on a:<\/p>\n 1\/4-inch medium-pressure tube system<\/strong>.<\/p>\n According to AMETEK, it is compatible with systems including:<\/p>\n This provides flexibility when integrating the comparator into existing high-pressure systems.<\/p>\n A modern calibration system can combine the:<\/p>\n AMETEK Crystal GaugeCal-HP<\/strong><\/p>\n with the:<\/p>\n AMETEK Crystal XP3i<\/strong>.<\/p>\n In this configuration:<\/p>\n GaugeCal-HP = Pressure Generator<\/strong><\/p>\n XP3i = Reference Pressure Gauge<\/strong><\/p>\n DUT = Device Under Test<\/strong><\/p>\n The GaugeCal-HP generates and controls the pressure while the XP3i provides the reference measurement.<\/p>\n This creates a portable high-pressure comparison system.<\/p>\n The GaugeCal-HP can also be used with the established:<\/p>\n AMETEK Crystal XP2i<\/strong>.<\/p>\n With appropriate XP2i reference ranges, these systems provide measurement capability extending to:<\/p>\n 15,000 psi \/ 1,000 bar<\/strong>.<\/p>\n This combination remains useful for laboratories already operating XP2i reference gauges.<\/p>\n AMETEK developed the GaugeCal-HP to make routine pressure gauge calibration faster and easier.<\/p>\n Traditional deadweight testers can provide excellent measurement performance but may require more setup time and operator effort.<\/p>\n The GaugeCal-HP instead uses a reference pressure gauge together with a manually operated pressure comparator.<\/p>\n This allows pressure points to be approached and adjusted rapidly.<\/p>\n The AMETEK Crystal GaugeCal-HP<\/strong> can also generate pressure for transmitter calibration.<\/p>\n The transmitter is connected to one pressure port while a suitable pressure reference is connected to the other.<\/p>\n The GaugeCal-HP generates the required calibration pressure.<\/p>\n An electrical calibrator or multimeter can then measure the transmitter output.<\/p>\n AMETEK also specifies the GaugeCal-HP for testing:<\/p>\n pressure safety valves<\/strong>.<\/p>\n The comparator generates the required hydraulic pressure while a suitable reference gauge monitors the applied pressure.<\/p>\n When used with an AMETEK Crystal digital pressure gauge equipped with a PSV function, the opening pressure of the valve can be determined conveniently.<\/p>\n The AMETEK Crystal GaugeCal-HP<\/strong> and XP3i perform completely different functions.<\/p>\n The:<\/p>\n GaugeCal-HP generates pressure.<\/strong><\/p>\n The:<\/p>\n XP3i measures pressure.<\/strong><\/p>\n Used together, they create a complete manual pressure comparison system.<\/p>\n This modular arrangement allows the pressure generator and reference instrument to be selected independently according to the calibration requirement.<\/p>\n A deadweight tester generates reference pressure based on calibrated masses, effective piston area and relevant correction factors.<\/p>\n The GaugeCal-HP follows a different principle.<\/p>\n It generates pressure mechanically but relies on a separate reference instrument to determine the actual pressure.<\/p>\n The GaugeCal-HP therefore does not replace the metrological function of a deadweight tester by itself.<\/p>\n Its major advantages are speed, convenience and portability when combined with a suitable digital reference pressure instrument.<\/p>\n The AMETEK Crystal GaugeCal-HP<\/strong> is suitable for:<\/p>\n The AMETEK Crystal GaugeCal-HP<\/strong> provides a practical solution for generating and adjusting pressure across an exceptionally broad range.<\/p>\n Hydraulic pressure can be generated up to 15,000 psi \/ 1,000 bar \/ 100 MPa<\/strong>, making the comparator suitable for demanding high-pressure calibration.<\/p>\n Water and oil can be used as hydraulic test media, while dedicated GOX and GWX configurations simplify selection for oil- or water-based applications.<\/p>\n Without hydraulic fluid, the GaugeCal-HP can also generate pneumatic pressure up to approximately 995 mbar<\/strong>, with fine adjustment sensitivity down to 0.025 mbar<\/strong>.<\/p>\n A pivoting two-port manifold simplifies connection of a reference instrument and device under test, including large pressure gauges.<\/p>\n The integral gauge-safe venting system helps protect mechanical gauges during pressure release, while the integrated drip tray simplifies hydraulic operation.<\/p>\n Combined with a precision reference such as the AMETEK Crystal XP3i<\/strong> or XP2i, the GaugeCal-HP forms a flexible manual pressure comparison system.<\/p>\n At europascal<\/strong>, we provide
