The Bently Nevada 330104‑00‑03‑10‑02‑00 is a high-precision eddy-current proximitor sensor designed for non-contact measurement of shaft vibration and displacement in rotating machinery. Part of the 3300 XL Proximitor Sensor Series, this model is widely used in industrial machinery monitoring, providing reliable, long-term performance for critical equipment.
This specific configuration includes a 3 mm sensing gap (code “03”), a 10 m integral cable length (code “10”), and a connector type code “02” which indicates a specific industrial connector compatible with certain monitoring modules. It outputs a standard analog voltage proportional to shaft displacement, allowing integration with vibration monitoring and protection systems.
The sensor works by creating an electromagnetic field near the sensor tip. As the conductive shaft moves within this field, changes are converted into voltage output, providing precise measurement of shaft position and vibration amplitude.
