330103-00-05-05-01-CN Proximity Probe Bently Nevada

Compact 8mm Proximity Probe for Tight Installations

The Bently Nevada 330103-00-05-05-01-CN belongs to the trusted 3300 XL series. We design this short 8mm probe for accurate displacement and vibration measurements in space-constrained locations. 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

Why choose this short probe?

The 50mm case length fits tight spaces where longer probes won't work. Ideal for compact machinery.

What is the connector protector?

It shields the ClickLoc connection from debris and accidental impact. Adds durability in harsh environments.

Compatible with 3300 XL systems?

Yes. This 330103-00-05-05-01-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 cable vs FluidLoc?

This model uses standard cable. Choose FluidLoc version for wet or oil-rich environments.
