New pressure comparator, test gauge have advanced safety features

A NEW hydraulic pressure comparator and a high-pressure version of the XP2i test gauge from Crystal Engineering are rated to 15,000 psi / 1000 bar / 100 MPa. Both offer industry-leading safety features that make testing and calibration either in the field or the laboratory possible.

Crystal Engineering, a unit of AMETEK Test & Calibration Instruments, produces field-grade testing and calibration equipment for measurement applications in oil and natural gas, power generation, waste water, water supply, manufacturing, aerospace, and aircraft maintenance

The pressure comparator, GaugeCalHP, is suitable for test and calibration use with water or oil, Key features include a fine adjust that is easy to use at 15,000 psi and a connection fitting with quick alignment swivel capability. A pivoting manifold rotates to fit large-size gauges. To increase stability, the device’s reservoir can quickly add a small amount of pressure to bleed air out of the weep hole. A drip tray captures excess fluid.

The patent-pending Crystal Pressure Fittings (CPF) add unique O-ring sealing for leak-free connections without tools The self-venting weep hole alerts users before they disconnect from a pressurized system. CPF fittings and hoses come with an industry first 4:1 safety factor.

Key features of 15,000-psi XP2i pressure gauge include IP-67 rated, marine-grade enclosure (submersible up to 1 meter), a fast pressure safety valve (PSV) mode and a leak-free Crystal pressure fitting connection. Active Digital Temperature Compensation assures 0.1% of reading accuracy from -10° to 50°C.

The dual display version adds additional features, including leak rate, tare mode, and differential pressure (when connected to a second XP2i). The optional DataLoggerXP upgrade lets users record up to 32,000 data points and export the data into Excel.
