Product Overview
The Bently Nevada 330905‑00‑18‑05‑02‑CN is a 3300 NSv compact‑body eddy‑current proximity probe assembly for non‑contact turbomachinery condition and protection monitoring. This complete unit includes stainless‑steel extended probe body, heat‑resistant FEP‑jacketed integral cable, and factory‑terminated ClickLoc coaxial connector, designed for pairing with compatible NSv‑type proximitor sensor. It captures micro‑level clearance changes 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 limited mounting space on dense machinery casings, signal instability from field‑performed splices, and performance degradation under moderate‑high casing temperature 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 long 18‑inch probe body suits deep, confined mounting bores, and consistent scale factor delivers repeatable measurement data for early identification of bearing wear, rotor misalignment and shaft instability to lower unplanned rotating‑equipment downtime.
Application Scenarios
- Gas Turbine Thrust and Radial Vibration Monitoring: Mounted on gas‑turbine bearing housings and interfaced to 3500 monitor racks. The extended‑length probe fits deep, restricted mounting holes on compact gas‑turbine casings, supplying continuous thrust‑position and vibration inputs for machinery alarm and automatic trip protection logic.
- Refinery Screw‑type & Centrifugal Compressor Condition Surveillance: Deployed for process compressors within petrochemical facilities. High‑temperature rated cable tolerates elevated casing ambient conditions, and the short 5‑meter cable length suits compact skid layouts with short routing distance to local control cabinets.
- Power Plant Critical Auxiliary Rotating‑equipment Protection: Used for high‑speed boiler feed‑water pumps and turbo‑expanders. Non‑contact eddy‑current measurement continuously tracks rotor dynamic behaviour, providing early warning for bearing degradation and rotor imbalance before severe mechanical failure occurs.
