The Bently Nevada 330104-12-20-10-01-00 proximity probe is a 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 engineered for demanding industrial environments where long-term signal stability, high measurement accuracy, and strong immunity to electromagnetic interference are essential for reliable machinery protection and condition monitoring.
The “12-20-10” configuration typically indicates a reinforced extended assembly designed for larger rotating equipment, where installation flexibility, stable signal transmission, and mechanical robustness are critical. The “-01-00” suffix generally refers to a standard connector and configuration variant used for broad compatibility within Bently Nevada monitoring systems.
