Bently Nevada 330104‑00‑11‑50‑02‑05
Comprehensive Product Overview (3300 XL 8 mm Proximity Probe Series)
1. Product Introduction
The 330104‑00‑11‑50‑02‑05 is a high‑precision industrial proximity probe engineered for continuous monitoring of shaft vibration, displacement, and rotor dynamics in heavy rotating machinery. It belongs to the 3300 XL 8 mm series, a globally established family of eddy current, non‑contact displacement sensors widely applied in condition monitoring and machinery protection systems.
Eddy current proximity probes detect changes in the electromagnetic field around their sensing tip when a conductive target (such as a shaft) moves relative to the probe. These changes are converted into stable electrical signals that represent vibration and position information. The 330104‑00‑11‑50‑02‑05 model is configured for an extended measurement range of 50 mm with enhanced sensitivity (“11” designation) and a standard industrial connector and cable length of 5 m (“02‑05”).
Designed for use in harsh industrial environments with high vibration, temperature extremes, moisture, and airborne contaminants, this probe is intended for mission‑critical monitoring and protection applications. Its robust construction and high resolution make it an ideal component of advanced machinery health systems.
