Gas pressure up to 11 MPa
PG7102 covers gauge and absolute pressures above atmosphere with gas as the pressurized medium. Absolute mode is supported by automated measurement and addition of atmospheric pressure, using PG7102?s internal barometer or any external barometer supporting RS-232 communications. PG7102 does not cover absolute or gauge pressures below atmospheric pressure.
The PG7102 includes all PG7000 standard features (see “Description” tab) as well as:
- Simplified gas operated platform does not include vacuum reference capability.
- Accepts same gas operated piston-cylinder modules as PG7601 platform.
PG7000 Piston Gauge line features reference level pressure standards offering a unified solution from vacuum to 500 MPa
- State-of-the-art primary pressure standards for the lowest uncertainty levels
- Unified solution from vacuum to 500 MPa
- Outputs fully validated reference pressures in real time
- Intuitive local operator interface
- Manual, semi-automated and fully automated configurations
The PG7000 Series calibration standards are based on the fundamental principle of mass loaded onto a piston to apply a known force to a known effective area.
Integrated piston-cylinder modules
Each PG7000 piston-cylinder is an integrated metrological assembly that includes the critical piston-cylinder mounting components. All of the mechanical parts that affect piston cylinder metrology are associated with the individual piston-cylinder, rather than being common parts of the piston gauge platform, enabling the user to:
- Change ranges (piston-cylinders) in seconds, without using tools.
- Handle and interchange piston-cylinders without exposing critical surfaces to contamination.
- Protect the piston-cylinder from damage due to accidental shock or impact when handling.
- Improve measurement reproducibility by avoiding frequent assembly/disassembly of mounting components.
- Improve piston-cylinder mounting design by allowing each mounting system to be optimized for a piston-cylinder size and range.
