YZS Series Double Needle Pressure Gauge is an industrial dual-needle pressure gauge, typically used to measure and display two independent pressure values or the high and low pressure ranges within the same system. Below are its key features and applications:
Key Features:
Dual-Needle Design
Two independent pointers (usually in different colors) can simultaneously display two pressure values, such as:
System operating pressure vs. peak/residual pressure.
Inlet and outlet pressure differences.
Pressure comparisons between two connected devices.
High Accuracy
Made with high-quality Bourdon tubes (e.g., copper alloy or stainless steel) for precise measurements.
Durable Construction
Shock-resistant case, suitable for high-vibration environments (e.g., machinery, hydraulic systems).
Some models are liquid-filled (e.g., glycerin or silicone oil) to dampen needle fluctuations.
Multiple Ranges & Units
Wide pressure ranges (e.g., 0–0.1 MPa to 60 MPa), with units in MPa, psi, bar, etc.
Flexible Installation
Standard connections (e.g., G1/4, M20×1.5) compatible with most industrial equipment.
Typical Applications:
Hydraulic Systems: Monitoring pump input/output pressure.
Compressors: Displaying operating pressure vs. safety limits.
Energy Equipment: Boilers, pipeline pressure monitoring.
Industrial Machinery: Textile, injection molding machines, etc., where dual pressure readings are required.
Model Explanation (e.g., YZS):
YZ: Likely stands for "Pressure Gauge" (from Chinese pinyin YaLi Biao).
S: May indicate "Dual-Needle" (Shuangzhen)
Naming conventions may vary by manufacturer-check specifications for details.
Important Notes:
When selecting, confirm the range, accuracy, and media compatibility (e.g., stainless steel for corrosive fluids).
Regular calibration is recommended to maintain accuracy.
