Product Overview
The Bently Nevada 330101‑00‑20‑10‑02‑CN is a 3300 XL 8 mm standard‑mount eddy‑current proximity probe assembly for non‑contact rotating‑machinery protection and condition monitoring. This complete unit includes stainless‑steel probe body, high‑temperature FEP‑sheathed integral cable, and factory‑terminated ClickLoc coaxial connector, designed for pairing with compatible 330180‑XX proximitor sensor. It captures tiny clearance variations between probe tip and rotating metallic target and transmits proportional analog signals for radial shaft vibration, thrust position and Keyphasor speed reference measurement. It addresses common field‑site pain points including signal drift and noise introduced by field‑performed splices, cable mechanical fatigue, and measurement degradation in high‑temperature machinery casing environments. Rotating‑machinery reliability engineers, vibration analysts and plant maintenance technicians benefit from this hardware; factory‑integrated one‑piece cable eliminates field‑splicing faults, the short 2‑inch probe body fits compact mounting threads, and consistent scale factor delivers repeatable measurement data for early identification of bearing wear, rotor misalignment and shaft instability to reduce unplanned rotating‑equipment
downtime.
Application Scenarios
- Gas Turbine Radial Vibration and Thrust Monitoring: Mounted on gas‑turbine bearing housings and connected to 3500 monitor racks. Compact 2‑inch probe body suits shallow threaded mounting holes on gas‑turbine casings, providing continuous thrust‑position and vibration inputs for machinery alarm and automatic trip protection logic.
- Petrochemical Small‑frame Centrifugal Compressor Surveillance: Deployed for compact‑skid process compressors in refineries. High‑temperature‑rated cable tolerates elevated casing ambient conditions, and the 10‑meter cable length supports routing from compressor skid to nearby control cabinet without intermediate splices.
- Power Plant Turbo‑expander and Critical Pump Protection: Used for high‑speed turbo‑expanders and boiler feed‑water pumps. Non‑contact eddy‑current measurement continuously tracks rotor dynamic behaviour, delivering early warning for bearing degradation and rotor imbalance before severe mechanical failure occurs.
