New Hydraulic Pressure Comparator

A new hydraulic pressure comparator with industry-leading safety features and a high-pressure version of its popular XP2i test gauge have been introduced by Crystal Engineering (USA) .Both the GaugeCalHP pressure comparator and high-pressure XP2i test gauge are rated to 15 000 psi / 1000 bar / 100 MPa.

Applications include: Oil & gas production, transmission and distribution, Laboratory, Power generation, Nuclear power, Water purification, Waste water treatment, Food Processing, Pharmaceutical manufacturing, Safety and Quality assurance.

The highly versatile GaugeCalHP is suitable for test and calibration use with water or oil, either in the field or the laboratory. 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.

Crystal Engineering’s rugged, intrinsically safe XP2i pressure gauge is now available for pressures up to 15,000 psi. Key features 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.
