It continuously measures the axial displacement of rotating shafts, providing early detection of potential shaft excursions that could cause contact between rotating and stationary components. This module is essential for safeguarding turbines, compressors, and other critical machinery against axial misalignment or thrust bearing failures.\u003c\/p\u003e\n\u003ch4\u003e\u003cstrong\u003eKey
