CRYSTAL Engineering has produced a hydraulic pressure comparator and a high pressure version of its popular XP2i test gauge for field and laboratory use.

Both the GaugeCalHP pressure comparator and high-pressure XP2i test gauge are rated to 15,000 psi, 1,000 bar and 100 MPa said Crystal, a unit of Ametek Test and Calibration instruments.

The GaugeCalHP is suitable for test and calibration use with water or oil, either in the field or the laboratory, boasting the patent-pending Crystal Pressure Fittings (CPF) which adds O-ring sealing for leak-free connections without tools.

Key features include a fine adjust that is easy to use at 15,000 psi, a connection fitting with quick alignment swivel capability and 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 self-venting weep hole. A drip tray captures the excess fluid from the hole, which alerts users before they disconnect from a pressurised system.

All CPF fittings and hoses come with an industry first 4:1 safety factor, with the newly available 15,000 psi rated XP2i pressure gauge boasting CPF connections.

Key features also include IP-67 rated, marine-grade enclosure (submersible up to 1 metre) and a fast pressure safety valve (PSV) mode.

Active digital temperature compensation on the device assures 0.1 per cent of reading accuracy from -10 to 50 degrees celsius.

The dual display version adds additional features, including leak rate, tare mode, and differential pressure when connected to a second XP2i, the company said.

The optional DataLoggerXP upgrade lets users record up to 32,000 data points and export the data into Excel.
