Product Overview
The Bently Nevada 330101‑00‑72‑20‑02‑CN is an 8 mm 3300 XL eddy‑current proximity probe assembly designed for non‑contact shaft vibration and thrust position measurement on rotating machinery. This complete unit includes stainless‑steel probe body, high‑temperature FEP‑sheathed integral cable and factory‑terminated ClickLoc coaxial connector, intended for pairing with a compatible 330180‑series proximitor sensor. It detects minute changes in clearance between probe tip and rotating metal target and transmits analog signal back to machinery monitor hardware. It resolves typical field‑equipment pain points such as signal degradation from loose field‑splice joints, cable mechanical fatigue, and measurement drift under high process‑temperature environments. Rotating‑machinery reliability engineers, vibration analysts and plant maintenance technicians benefit from this hardware; factory‑integrated cable construction eliminates field splicing risk, wide operating temperature range suits hot machinery casings, and consistent scale factor delivers repeatable vibration and thrust readings for early fault detection of bearings, rotors and shaft assemblies.
Application Scenarios
- Steam Turbine Thrust & Radial Vibration Monitoring: Mounted on turbine bearing housings, paired with proximitor and 3500 monitoring racks. Captures both steady‑state thrust position and high‑frequency radial vibration, feeding protection logic for automatic machine trip when abnormal rotor movement occurs.
- Petrochemical Centrifugal Compressor Condition Monitoring: Deployed on multi‑stage process compressors. High‑temperature cable construction tolerates hot casing ambient conditions, continuous non‑contact measurement tracks rotor dynamics during startup, load ramping and normal production operation.
- Heavy‑Duty Industrial Fan & Blower Protection: Installed on large critical‑service fans inside power and process plants. Long 20 m integrated cable length simplifies routing from machine casing to remote control cabinet without intermediate splices, maintaining signal integrity for continuous condition‑based monitoring.
