The Bently Nevada 330104-16-21-05-01-RU proximity probe is a high-precision eddy-current sensor designed for continuous, non-contact measurement of shaft vibration, radial displacement, and rotor position in rotating machinery.
Built on the proven 3300 XL 8 mm proximity transducer platform, this probe is widely used in industrial condition monitoring systems where long-term stability, high measurement accuracy, and strong resistance to electromagnetic interference are essential for reliable machinery protection.
The “16-21-05” configuration typically represents a specialized extended probe assembly designed for complex installation environments requiring flexible routing and stable mechanical integration. The “-RU” suffix generally indicates a Russia-region variant, often associated with localized compliance, documentation, or supply-chain configuration for regional industrial standards.
