Core Application & Target User Overview
This guide covers specialized pressure gauges of YXA, YSF6, and MSF6 series, tailored for measuring pressure of special media (ammonia, sulfur hexafluoride) in industrial systems. YXA series is compatible with ammonia refrigeration equipment, chemical ammonia storage tanks, and ammonia-based fertilizer production lines; YSF6 and MSF6 series fit sulfur hexafluoride (SF6) electrical equipment (GIS, circuit breakers) and SF6 gas insulation systems. Targeting refrigeration engineers, power equipment maintenance teams, chemical plant technicians, and power grid enterprises, it addresses the critical demand for media-compatible, corrosion-resistant pressure measurement tools to avoid media leakage, equipment corrosion, or operational accidents caused by incompatible gauges. All products comply with EN 837-1 (pressure gauge technical specifications), IEC 60529 (IP65 protection rating), and relevant media compatibility standards (e.g., GB/T 26249 for ammonia equipment, IEC 60480 for SF6 equipment), undergoing rigorous corrosion resistance and accuracy testing.
YXA Series Ammonia Electric-Contact Pressure Gauges
YXA Series Ammonia Electric-Contact Pressure Gauges are exclusively designed for ammonia (NH₃) media scenarios, integrating pressure measurement and electric control functions. Ammonia’s strong corrosiveness and toxicity make incompatible gauges prone to leakage, posing safety hazards. Our YXA gauges adopt ammonia-resistant materials and sealed structures, ensuring reliable pressure monitoring and alarm/control signal output for ammonia refrigeration units, storage tanks, and transport pipelines, with accuracy class up to 1.5.
Field Application Case
A cold storage enterprise encountered frequent corrosion and leakage of ordinary pressure gauges in their ammonia refrigeration system, leading to 2 ammonia leakage incidents and unplanned shutdowns. After replacing with YXA-100ZT ammonia electric-contact pressure gauges (complying with EN 837-1 and GB/T 26249), the system operated stably for 18 months without leakage. The gauges accurately triggered alarm signals when ammonia pressure deviated from 0.6-1.2MPa, ensuring operational safety and reducing maintenance costs by 60%.
