Core Application & Target User Overview
This guide covers professional electric contact pressure gauges of YX, YTNX, and YXC series, compatible with industrial equipment and systems including hydraulic/pneumatic machinery, boiler systems, water supply pipelines, chemical reactors, and oil & gas transmission lines. Tailored for plant maintenance engineers, process control technicians, power generation enterprises, and chemical processing plants, it addresses the critical demand for pressure measurement with automatic alarm and control functions to avoid equipment overpressure damage, production accidents, or process disruption caused by manual monitoring delays. All products comply with EN 837-1 (pressure gauge technical specifications), IEC 60947-1 (electrical contact safety standards), and IP65 protection rating requirements, undergoing rigorous accuracy calibration and vibration resistance testing to ensure reliable performance in harsh industrial environments (vibration, humidity, and corrosive gas).
YX Series Electric Contact Pressure Gauges
YX Series Electric Contact Pressure Gauges integrate pressure measurement and electrical control functions, triggering alarm or control signals when pressure reaches preset upper/lower limits. They are widely used in general industrial pressure monitoring scenarios such as water supply systems and ordinary hydraulic equipment. Premature failure (contact jitter, accuracy drift) can lead to false alarms or failure to trigger protection measures, causing equipment damage. Our YX gauges adopt silver-plated electrical contacts and precision movement structures, ensuring stable contact performance and measurement accuracy class up to 1.5.
Field Application Case
A food processing plant encountered frequent false alarms with ordinary pressure gauges in their steam boiler pressure monitoring system, leading to unnecessary production interruptions. After replacing with YX-100Z electric contact pressure gauges (complying with EN 837-1), the false alarm rate dropped to zero. The gauges accurately triggered alarm signals when steam pressure exceeded 1.2MPa, ensuring boiler operation safety and reducing production downtime by 20% within 6 months.

YTNX Series Shock-Proof Electric Contact Pressure Gauges
YTNX Series Shock-Proof Electric Contact Pressure Gauges are specialized for high-vibration industrial scenarios such as construction machinery, mining equipment, and high-pressure pumps. The internal filling of shock-proof oil and reinforced movement structure effectively reduce vibration impact, ensuring stable pressure measurement and contact signal output. Premature failure (oil leakage, contact damage) can lead to loss of pressure monitoring and control functions, causing equipment overload. Our YTNX gauges adopt high-seal oil-filled structures and wear-resistant contacts, ensuring reliable operation in strong vibration environments (vibration frequency 10-50Hz).
