Crystal Engineering introduces new handheld pressure calibrator

Crystal Engineering, a unit of Ametek Test & Calibration Instruments, has released a new handheld pressure calibrator, engineered for 'advanced simplicity'. 

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 on-site, field usable instrument. The 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 to 50 degrees Celsius, 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 also can be used along with a reference temperature detector as a high-accuracy thermometer. 

The calibrator features a large, full-colour display and a new user interface. 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 settings 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 000psi/700bar and ensure leak-free connections without the use of tools. In addition, the fittings’ self-ventilating weep holes alert users when disconnecting from a pressurised system. 

The HPC40 Series can be used as an individual calibrator or combined with Ametek pressure generating products into a 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 15,000psi/1000bar.
