Applications
The 21504-00-12-10-02 probe is versatile and finds its utility in several high-value and high-risk machinery monitoring applications, including:
-
Steam and gas turbines (vibration and axial position monitoring)
-
Centrifugal compressors (shaft vibration and thrust position)
-
Electric motors and generators (rotor dynamics observation)
-
Pumps and fans (vibration and dynamic displacement analysis)
-
Gearboxes (shaft monitoring for early fault detection)
-
Industrial process equipment with rotating elements
The non-contact nature / the probe makes it ideal for continuous, long-term monitoring where probe-to-target interaction must be avoided.
