Description
Bently Nevada 330101-00-16-10-02-00 3300 XL 8 mm Proximity Probe
Configured for eddy-current displacement measurement in Bently Nevada 3300 XL series machinery protection systems, the Bently Nevada 330101-00-16-10-02-00 (base model 330101) provides direct physical interface to rotating shaft proximity sensing circuits. It converts radial vibration or position into proportional voltage signals for real-time machinery condition monitoring.

Eddy-Current Probe Scaling & Gap Voltage Validation
The probe operates with a linear range defined by target material conductivity and surface finish. For accurate scaling, perform gap voltage validation against a -10 VDC nominal bias point using a calibrated driver/demodulator. Rotor dynamics measurements require consistent probe mounting perpendicularity to avoid cross-talk suppression degradation between adjacent sensors. Calibration should be executed at the installed extension cable length to preserve system accuracy.
Frequently Asked Questions
Q: Can this probe be used with armored cable assemblies?
A: No. This configuration specifies an unarmored standard cable; substitution requires recertification of mechanical and electrical characteristics.
Q: What is the maximum permissible probe insertion depth?
A: Insertion must not exceed the case length minus thread engagement, ensuring no contact with rotating components under thermal expansion.
Q: Is hot-swapping supported on live machinery?
A: No. Always de-energize the associated signal conditioner before probe replacement to prevent transient overvoltage damage.
Field Installation Guidelines
Mount the probe using the supplied 3/8-24 UNF threads, torqued to manufacturer-recommended values. Maintain proper standoff from the shaft surface to achieve specified gap voltage. Ground the shield at the signal conditioner end only to prevent ground loops. Route cables away from high-current conductors and motor leads to minimize electromagnetic interference. Verify clearance during shaft rotation and thermal growth conditions prior to final tightening.
