AMETEK STC’s HPC50 Calibrator Receives CSA Intrinsic Safety Rating for North American Markets

SAN LUIS OBISPO, CA, Oct. 30, 2019 – AMETEK STC is pleased to announce that the HPC50 Handheld Pressure Calibrator released earlier this year now has a CSA Intrinsic Safety rating, expanding its availability to the North American Intrinsically Safe market, specifically the Oil and Gas sector.

The HPC50 pressure calibrator uses a similar non-menu interface to the one found in the popular HPC40 series calibrator. This easy-to-use, single-layer interface has no deep menu structure, allowing users to quickly and intuitively perform tasks. Intelligent memory slots allow storage of up to five screens, simplifying the recall of previously stored settings and user setups.

The calibrator offers deadweight tester accuracy along with a host of user-friendly features that deliver laboratory accuracy to an on-site, field usable instrument. The versatile HPC50 is suitable for calibrating pressure ranging from vacuum to 10,000 psi / 700 bar with accuracy up to 0.035% of reading. It is ideal for process control applications, such as verification or calibration of pressure gauges, transducers, transmitters, pressure switches, and safety valves.

Units are available in single and dual pressure models. Users can equip each with one or two new, intrinsically safe external pressure or temperature modules.

The connection ports on the side of the HPC50 support the new intrinsically safe APMi pressure modules, which provide the flexibility to read up to four pressure inputs with a single device, allowing users to either expand the range of their HPC50, view all four pressures simultaneously, or to read two different differential pressures.

Alternatively, users can also connect the HPC50 with two new ATMi intrinsically safe temperature modules, which AMETEK STC is introducing at the same time. These modules provide the flexibility to read pressure using the installed modules and, at the same time, read both static and ambient temperatures.

All parameters on the HPC50 series are fully temperature compensated from -20 to 50°C, enabling it to deliver the same accuracy whether measuring pressure, current, voltage, or temperature.

The HPC50 is the perfect instrument for the oil and gas industry because of its intrinsically safe ratings, expanded pressure ranges, and versatility. Some of the most common applications include maintenance and troubleshooting of gauges, switches, transmitters, transducers, valves, gas meters, flow computers, pumps, and filters. It can also replace a deadweight tester with a single handheld unit.

AMETEK STC (Sensors, Test, & Calibration) is among the world’s leading manufacturers of calibration instruments for temperature, pressure, and process signals. For more information on the full line of Jofra and Crystal Engineering calibration products visit
