Description
Bently Nevada 330101-00-40-05-02-00 3300 XL 8 mm Proximity Probe
The Bently Nevada 330101-00-40-05-02-00, also cataloged as the 330101 proximity probe, executes non-contact shaft displacement measurement within 3300 XL series transducer systems. It converts radial position into proportional DC voltage via eddy-current interaction, directly interfacing with target monitoring racks through a miniature coaxial ClickLoc connector.

Eddy-Current Probe Scaling and Gap Voltage Validation
The 330101 probe maintains a fixed linear scaling ratio when paired with a matched driver and extension cable. Calibration requires verification of gap voltage at the driver output, targeting -10 VDC for mid-scale mechanical clearance. Eddy-current field geometry ensures cross-talk suppression between adjacent probes when installed per minimum separation distances defined in the 3300 XL mechanical mounting guidelines.
Frequently Asked Questions
Q: Is the 330101 probe hot-swappable in live systems?
A: No. The probe must be disconnected only after powering down the associated monitor module to prevent transient voltage spikes on the signal line.
Q: What is the minimum bending radius for the standard cable?
A: Maintain a bend radius of no less than 25.4 mm to avoid impedance changes that affect measurement accuracy.
Q: Can this probe be used without armor?
A: Yes. This model is unarmored; installation must ensure physical protection from mechanical impact and excessive vibration.
Field Installation Guidelines
Mount the probe using the 3/8-24 UNF thread, ensuring at least five full threads engagement into the machined mounting bracket. Avoid applying axial preload beyond the specified probe tip clearance. Route the coaxial cable separately from high-voltage AC wiring to maintain shielding integrity. Terminate the shield at the monitor end only, leaving the probe end floating to prevent ground loops. Verify gap voltage post-installation before placing machinery into service.
