Power Generation Industry
Measures the relative thermal growth discrepancy between the steam turbine rotor and casing during startup and shutdown to prevent catastrophic rubs.

Oil & Gas Industry
Detects sudden shaft shifts or heavy vibrations in high-pressure process gas compressors to trigger emergency trip systems.

Chemical & Heavy Processing Industries
Functions as a critical input for critical safety interlock systems by continuously reporting rotor axial position in aggressive chemical areas.

Metallurgy & Mining Industries
Monitors the vast rotor displacement in steel plant air-supply blowers to handle high temperature and high volume air stress.

Marine, Water & General Heavy Machinery
Tracks propeller shaft thrust position changes caused by maritime hull flexing and varying marine propulsion thrusts. Monitors the relative positioning of low-speed high-torque shafts to protect internal gear meshes from uneven loading.
