Generator Displacement Monitoring System

Generator displacement caused by improper installation, misalignment, or loose or broken fastening bolts seriously disrupts turbine operation, increases vibration and damages generator bearings, gearbox high-speed shaft bearings and other components. Online displacement monitoring captures actual movement in multiple spatial dimensions. Combined with vibration monitoring, it supports effective analysis and quantitative study of displacement effects on bearing motion, detects loose or broken fasteners and prevents major accidents.

Monitoring Challenges

Distortion from Indirect Measurement

Displacement inferred from vibration or acceleration can be distorted, with unclear fault signatures.

Poor Environmental Adaptability

Strong electromagnetic interference, temperature extremes and vibration cause sensor drift and unstable signals.

Delayed Early Warning

Undetected micro-displacement delays identification of rotor eccentricity and uneven air gaps.

Single monitoring dimension

Single-point, single-direction monitoring cannot provide coordinated analysis across locations.

Product Advantages

Direct, Accurate Measurement

Non-contact, high-precision direct measurement of absolute displacement accurately captures rotor, stator and base movement, providing reliable raw diagnostic data.

Exceptional Environmental Adaptability

Resistant to electromagnetic interference, oil contamination and vibration, with stability across a wide temperature range. Requires no optical lens, is unaffected by dust or fog, and offers zero drift over long-term operation.

Early Warning

Micrometer-level sensitivity detects tiny displacement changes and identifies stator/rotor eccentricity and other risks early, enabling prompt detection, warning and action.

Coordinated Multidimensional Monitoring

Supports radial, axial, horizontal and vertical layouts to simultaneously monitor rotor–stator and base–support relative displacement, establishing comprehensive displacement monitoring.
