Functional Description
The 128987‑130‑00‑00 probe measures the distance between its tip and a conductive target surface, typically a rotating shaft. This measurement is used to detect shaft vibration, axial position, and mechanical condition changes. Its 8 mm design offers a wide linear operating range and high sensitivity, enabling accurate diagnostics across a broad frequency spectrum.
The probe’s stainless‑steel housing provides mechanical durability in harsh industrial environments. A factory‑installed cable and connector ensure consistent signal quality and simplify integration with Bently Nevada proximitor sensors and monitoring systems. The extended 130‑inch cable allows flexible routing in confined or complex machinery layouts.
Application Scenarios
