Functional Characteristics

• Non-Contact Measurement: Utilizes eddy current effect to measure displacement without physical contact, avoiding wear and interference with machinery operation.
• High Precision: Nanometer-level resolution enables detection of subtle vibrations and early-stage faults.
• Wide Frequency Response: Captures both low-frequency (e.g., imbalance) and high-frequency (e.g., bearing faults) vibrations.
• Robust Design: Stainless steel housing with IP67 rating resists high pressure, chemicals, and physical impact.
• Anti-Interference: Multi-stage shielding and high-frequency low-pass filters eliminate power noise and electromagnetic interference.
• Easy Installation: Supports multiple thread sizes and installation accessories; probe, extension cable, and front-end module are interchangeable without separate calibration.
• Self-Diagnostic: Monitors coil impedance to detect probe aging, cable faults, or excessive gap, triggering alarms (e.g., code E015).

Application Scenarios

• Power Generation: Monitoring turbine shaft vibration, axial displacement, and speed in steam/gas turbines and generators.
• Petrochemical: Protecting compressors, pumps, and expanders from vibration-induced failures in explosive environments.
• Metallurgy: Managing health of blast furnace blowers, sintering fans, and rolling mill motors to ensure continuous production.
• Marine & Offshore: Safeguarding propulsion systems and critical machinery on ships and drilling platforms.
• Water Treatment: Controlling pump vibration levels to prevent cavitation and mechanical wear.
• Research & Development: Supporting rotor dynamics studies and mechanical vibration analysis in high-precision experimental setups.

Key Advantages

• Early Fault Detection: Timely capture of equipment imbalance, misalignment, and bearing wear signals prevents sudden shutdowns.
• Extended Equipment Lifespan: Non-contact measurement reduces mechanical losses, and anti-interference design ensures long-term stable operation.
• Reduced Maintenance Costs: Interchangeable components and easy installation shorten maintenance time and lower spare part costs.
• Global Compliance: Meets international standards for safety and performance in hazardous zones (Class I Div 1).
