330103-00-21-10-11-CN Probe Bently Nevada

Precision 8mm Proximity Probe with FluidLoc Cable

The Bently Nevada 330103-00-21-10-11-CN belongs to the trusted 3300 XL series. We design this 8mm probe for accurate displacement and vibration measurements in harsh industrial environments. It operates within a 2mm (80 mils) linear range, starting at 0.25 mm from the target. For radial vibration monitoring, we recommend a gap setting of -9 Vdc, which equals approximately 1.27 mm. This sensor provides reliable data for protecting turbines, compressors, and other rotating equipment.

Frequently Asked Questions

What is FluidLoc cable?

FluidLoc resists moisture migration along the cable. It prevents fluid from reaching connection points in wet environments.

Why zero unthreaded length?

The 00 option means threading starts immediately at tip. Ideal for shallow holes or maximum thread engagement.

Compatible with 3300 XL systems?

Yes. This 330103-00-21-10-11-CN works with all Bently Nevada 3300 XL proximitors and monitors.

What gap setting for vibration?

Set initial gap to -9 Vdc (approximately 1.27mm). This centers probe within linear range.

Standard vs FluidLoc cable?

Choose FluidLoc for wet/oil environments. Choose standard cable for dry industrial conditions.
