Application Scenarios

Compact Centrifugal Compressors

The NSv probe is optimized for compressors with limited probe mounting space. It continuously measures radial shaft vibration and displacement, allowing operators to identify imbalance, bearing deterioration, or shaft instability before process reliability is affected.

Steam Turbines and Industrial Turbomachinery

Installed alongside compatible Proximitor Sensors, the probe provides continuous shaft position and vibration measurements for turbine protection systems. Its high-resolution displacement monitoring supports both machinery protection and long-term condition monitoring programs.

Electric Motors and Gearboxes

Where standard proximity probes cannot be installed because of restricted clearances, the NSv design enables accurate shaft movement monitoring without mechanical contact. Maintenance personnel can trend vibration data to detect developing faults and schedule maintenance before unexpected shutdowns occur.
