Yunyi Factory Higher Accuracy Pressure Gauge Calibrator Hydraulic Calibrate Pressure Gauge Dead Weight Tester

1. Operating Principle
Based on the Pascal principle and piston-type pressure balance, this system generates a standard pressure on the piston system by loading weights and hydraulic fluid (or gas), enabling precise pressure measurement or calibration.

2. Typical Structure
Piston Assembly: High-hardness, low-friction piston and cylinder ensure long-term stability.
Weight Set: Precision-machined weights of known mass used to generate standard pressure values.
Pressure Port: Compatible with a variety of test devices (such as pressure sensors, transmitters, and instruments).
Hydraulic Fluid System: Select models use an inert liquid medium (such as silicone oil) to reduce gas compressibility errors.

3. Applications
Calibration of pressure sensors, transmitters, and pressure gauges.
Laboratory pressure reference transfer (compliant with ISO 17025).
High-precision pressure testing in industrial applications (such as the petroleum, chemical, and aerospace industries).
