Handheld Pressure Calibrator for Process Control Delivers Lab Accuracy in Field Use

摘要

A new handheld pressure calibrator that delivers deadweight tester accuracy in an on-site instrument has been introduced by Crystal Engineering, a unit of Ametek Test & Calibration Instruments. The versatile HPC40 Series calibrator is designed for process control applications, such as verification or calibration of pressure gauges, transducers, transmitters, pressure switches and safety valves. It is suitable for pressures ranging from vacuum to 15,000 psi with accuracy of 0.035% of reading for all ranges. The HPC40 Series is the world's first mA loop calibrator that is fully temperature compensated from -20o to 50oC, the company reports. This enables it to deliver the same accuracy whether measuring pressure, current, voltage or temperature.
