Crystal Engineering HPC40 Series pressure calibrators

Oilfield Technology,

The new HPC40 Series handheld pressure calibrator from Crystal Engineering, a unit of AMETEK Test & Calibration Instruments, is engineered for ‘advanced simplicity’, incorporating a number of useful features that greatly extend the range and functionality of the compact instrument.

The HPC40 Series offers deadweight tester accuracy along with a host of user friendly features that allow the handheld device to deliver laboratory accuracy to an onsite, field usable instrument. The versatile HPC40 Series is suitable for calibrating pressures ranging from vacuum to 15 000 psi with accuracy of 0.035% of reading for all ranges. It is ideal for process control applications, such as verification or calibration of pressure gauges, transducers, transmitters, pressure switches and safety valves.

The HPC40 Series is also the world’s first mA loop calibrator that is fully temperature compensated from -20 °C – 50 °C, enabling it to deliver the same accuracy whether measuring pressure, current, voltage or temperature.

A single HPC40 Series device can typically replace several gauges or calibrators. With the addition of a Crystal Engineering Advance Pressure Module, the calibrator can read up to three pressures using a single device and the differential pressure between any two. It is available in a single or dual sensor option and it can also be used along with a reference temperature detector as a high accuracy thermometer.

The calibrator’s large, full colour display combined with its new user interface makes the HPC40 Series the easiest to use pressure calibrators available. Its single layer user interface has no deep menu structure, allowing tasks to be performed quickly and intuitively. Its intelligent memory slots allow the HPC40 Series to store up to five screens (both upper and lower windows) simplifying recall of previous stored setting and user setups.

Another unique feature is its use of newly patented Crystal Pressure Fittings. These 316 stainless steel fittings are designed to operate at 10 000 psi/700 bar and ensure leak free connections without the use of tools. In addition, the fittings’ self ventilating weep holes alert users when disconnecting from a pressurized system.

The HPC40 Series can be used as an individual calibrator or combined with AMETEK pressure generating products into a complete ready to use calibration system. These products include everything from small pneumatic hand pumps to precision, hydraulic pressure comparators able to generate up to 15 000 psi/1000 bar.
