The Bently Nevada 330104-16-21-10-01-00 proximity probe is a high-performance 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, measurement accuracy, and strong immunity to electromagnetic interference are essential for reliable machine protection.
The “16-21-10” configuration typically represents an extended probe assembly optimized for medium-to-large rotating equipment installations requiring deeper mounting reach and stable mechanical integration. The “-01-00” suffix generally indicates a standard connector and cable configuration used for broad system compatibility within Bently Nevada monitoring architectures.
