In an industrial fan maintenance system, what physical change might a sensor detect?

Vibration is the physical change sensors in this context are most likely to detect. When a fan develops issues like imbalance, misalignment, bearing wear, or looseness, the machine’s movement changes and those changes show up as altered vibration patterns. A vibration sensor, such as an accelerometer, directly measures these oscillations—their amplitude and frequency—providing early signs of mechanical faults. Power or blade speed can be measured as electrical or rotational parameters, but they don’t reflect a fault occurring in the machine’s mechanical condition in the same direct way. Wind direction is environmental and not a symptom of the fan’s internal health.
