The Bently Nevada 330104-00-11-90-02-00 proximity probe is a high-performance eddy-current sensor designed for continuous, non-contact measurement of shaft vibration, radial displacement, and rotor position in critical rotating machinery.

Built on the widely proven 3300 XL 8 mm platform, this configuration is engineered for demanding industrial environments such as turbines, compressors, and generator trains where measurement stability and long-distance signal integrity are essential for safe and reliable operation.

The “90” configuration is typically associated with extended system cable length, making this model suitable for large plant layouts where the monitoring system is installed far from the machine skid. The 02-00 connector and standard industrial configuration ensure straightforward integration into common Bently Nevada monitoring architectures.
