330104-00-15-10-02-00 Bently Nevada 3300 XL 8 mm Proximity Probe

Bently Nevada 330104-00-15-10-02-00 is basically a 3300 XL 8 mm eddy current proximity probe with a fixed factory build.

330104 means forward-mounted M10×1 metric probe with stainless armor.
Suffix details: 0 mm unthreaded (fully threaded body), about 150 mm case length, and 1.0 m integrated cable. Connector is standard ClickLoc coaxial, gold-plated, no protector.

It’s a 1-meter integral system, not a long-loop type. So it connects directly to a matching 3300 XL Proximitor sensor (1 m version). Adding an extension cable changes loop capacitance/impedance, and signal stability will drift. In practice, it’s just run as a direct one-to-one connection.

Used on heavy rotating machines like steam turbines, gas turbines, compressors, and pumps. Main measurements: radial vibration, axial position, and sometimes Keyphasor speed reference. Armored cable helps in oil mist and high-vibration bearing zones where cables get mechanical stress.

With a standard 3300 XL Proximitor sensor, it runs a 2.0 mm linear range, roughly 0.25–2.3 mm gap. Scale factor is 7.87 V/mm (200 mV/mil), and normal setup sits near -9 Vdc bias (~1.27 mm gap) for stable vibration tracking. Just basic alignment and spacing matter most.

Yes, it works with legacy 3300 non-XL systems, but performance depends on the weakest component in the loop. It will run, but accuracy and stability are limited by older Proximitor or rack modules. For best results, it’s usually kept in a full 3300 XL + 3500 system aligned with API 670 practice.
