Core Advantages
1. Ultra-High Precision
Accuracy ranges from ±0.005% FS (full scale) to ±0.02% FS, significantly exceeding that of conventional pressure gauges, making it suitable as a reference instrument.
2. Long-Term Stability
The piston and cylinder are made of wear-resistant materials such as tungsten carbide, resulting in minimal wear, excellent stability, and a long calibration cycle.
3. Wide Measuring Range
This pressure range covers from a few kPa to 1 GPa, and can be flexibly adjusted by replacing weights and piston modules.
4. Direct Traceability to International Standards
Pressure is generated based on the weight's gravity, with a simple theoretical model that is directly traceable to International Units (SI) for mass, length, and time.
5. Low Temperature Sensitivity
Some models feature temperature compensation to minimize the effects of ambient temperature on the density of the medium and the effective piston area.
6. Versatility
This pressure gauge supports absolute, gauge, and differential pressure modes, and is compatible with a variety of pressure units (MPa, psi, bar, etc.).
Some high-end models integrate automatic pressurization, data acquisition, and software analysis.
7. Compliance with International Standards
This instrument complies with metrological standards such as ISO 8763, ASTM E2785, and JJG 59, making it suitable for use by legal metrology institutions and accredited laboratories.
