Applications
The 330102-12-60-10-02-05 proximity probe is designed for industrial machinery where accurate shaft measurement and long-term sensor durability are essential.
Typical applications include:
-
Steam turbine vibration monitoring
-
Gas turbine protection systems
-
Centrifugal compressor monitoring
-
Generator shaft displacement measurement
-
Industrial motor condition monitoring
-
Large pump monitoring
-
Gearbox vibration analysis
-
