Core Purpose Statement
This guide covers YN/Y series stainless steel (SS) pressure gauges, including models like YN-100BF-ZQ, Y-60B-F, and YN-153B-F. These gauges are specifically designed to match equipment such as stainless steel pressure vessels (e.g., 304/316L storage tanks), chemical pumps (IH series), food-grade pipelines, and marine hydraulic systems. Targeted at petrochemical plants, food & beverage manufacturers, marine engineering firms, and pharmaceutical enterprises, they address core needs for corrosion resistance, pressure measurement accuracy, and stable operation in harsh environments (corrosive media, vibration, high humidity). Compliant with EN 837-1 and GB/T 1226-2010 standards, they eliminate risks of gauge failure caused by corrosive media and vibration, ensuring reliable pressure monitoring for critical industrial processes.

Procurement & Technical Reference Standards
1. Procurement Reference Standards
Certification Compliance: Prioritize products certified to EN 837-1 (European standard) and GB/T 1226-2010 (Chinese national standard), with materials meeting ASTM A240 (stainless steel) requirements. For hazardous environments, ensure compliance with ATEX Zone 2 certification.
Parameter Matching: Confirm the gauge's rated pressure range (match 1.5-2 times the measured pressure), accuracy class (≥1.6 for industrial use, ≥1.0 for precision applications), dial diameter (based on installation space and readability needs), and wetted part material (316L/316Ti/Hastelloy) matching the measured medium.
Environmental Adaptability: Select filling media (silicone oil/glycerin) based on vibration level (high viscosity for strong vibration) and temperature range (-20℃ to 120℃ for standard filling, -40℃ to 150℃ for high-temperature filling). Choose sealing rings (EPDM/PTFE/fluororubber) based on chemical compatibility with the environment.
Quality & Reliability: Verify the gauge's overpressure capacity (≥150% of rated pressure), service life (≥50,000 pressure cycles), and leak-tightness (tested at 1.25 times rated pressure for 30 minutes). Check the manufacturer's ISO 9001 quality management system certification.
2. Technical Problem-Solving Reference Standards
Inaccurate Measurement: Check for calibration drift, pressure element damage, or filling media contamination. Recalibrate the gauge using a dead-weight tester or precision calibration pump (calibration interval: 6-12 months). Replace the pressure element or filling media if calibration fails.
Gauge Leakage: Inspect sealing rings, bezel screws, and pressure connections for looseness or damage. Replace worn sealing rings with compatible materials, retighten bezel screws to specified torque, and use thread sealant for pressure connections. Conduct a leak test with nitrogen after repair.
Vibration-Induced Damage: Verify if the filling media is suitable for the vibration level. Replace standard filling with high-viscosity silicone oil or glycerin. Install vibration isolation brackets or dampers between the gauge and the pipeline. Ensure the gauge is mounted perpendicular to the vibration direction.
Corrosion Issues: Check if the wetted parts and case material are compatible with the measured medium and environment. Upgrade to corrosion-resistant materials (e.g., 316Ti, Hastelloy) if needed. Apply anti-corrosion coatings to the case surface and install a chemical-resistant protective cover.
