Tracking shaft displacement and vibration in turbines (steam, gas, hydro) to detect imbalance or misalignment
-
Enabling preventative protection for compressors and large pumps against rub, bearing fatigue, or instability
-
Supporting condition monitoring in generators, detecting shaft run‑out or bow
-
Ideal for use in petrochemical, power, or heavy‑industry environments where consistent downstream diagnostics are essential
-
Providing early warning in hazardous or high‑vibration zones where fast, accurate sensor interfaces are required
4. Key Advantages
