Performance Features
1. High Accuracy and Stability: Accuracy class up to 0.005, measurement uncertainty better than ±0.005%. Ceramic piston rod and tungsten carbide piston cylinder ensure wear resistance, corrosion resistance, low thermal expansion coefficient, and exceptional long-term stability.
2. Multifunctionality and Flexibility: Supports absolute pressure, gauge pressure, and vacuum pressure measurement modes for versatile applications. Equipped with multiple piston systems covering a wide range from 5 kPa to 6 MPa, eliminating frequent equipment changes.
3. Intelligence and Convenience: Integrated electric control for piston rotation eliminates manual intervention inside the vacuum chamber. Features a digital display module for real-time monitoring of pressure, temperature, rotational speed, and other parameters.
4. Environmental Adaptability: Utilizes gas media (nitrogen/clean air) to eliminate liquid viscosity effects and enhance sensitivity; incorporates a multi-stage filtration system to effectively prevent dust contamination of the piston system.
5. Optimized Structural Design: Features a lightweight base for easy transport; employs quick-seal connectors and a vacuum chamber design to significantly reduce leakage risks.
Typical Applications
Verification or calibration of absolute pressure digital pressure gauges, absolute pressure precision pressure gauges, pressure transmitters, pressure sensors, and other instruments.
Serves as a reference device for pressure value transfer, supporting national metrology institutions, third-party testing laboratories, and high-end manufacturing sectors.
Suitable for demanding absolute pressure measurement scenarios in aerospace, meteorology, scientific research, and other fields.
