4. Product Introduction

The Bently Nevada 330106-05-30-90-02-05(CN) is a 3300 XL 8 mm reverse mount proximity probe with M10 x 1 threads. It delivers vibration and position measurements for critical rotating machinery in the 3300 series monitoring systems.

This reverse mount design allows installation from inside the machine case in tight spaces. The XL series offers improved RFI/EMI immunity and temperature performance over older 3300 probes. Technicians use these in turbines, compressors, and pumps where reliable gap and vibration data are essential.

5. Troubleshooting Quick Reference

Symptom Possible Cause Relevance to this Part Quick Check Method Recommendation
No gap voltage Probe not connected or damaged High Measure -1 to -24 V DC at Proximitor output Check cable connections and probe seating
Unstable readings Excessive shaft runout or probe gap High Verify gap is within linear range (typically 10-90 mils) Adjust probe position; check target surface
No signal at monitor Extension cable fault Medium Test continuity and capacitance of cable Replace extension cable if open or shorted
Erratic output EMI or grounding issue Low Check shield grounding Ensure single-point ground per manual
Temperature drift Exceeded probe rating Low Monitor case temperature Use high-temp version if needed

Send probe serial, installation photos, gap voltage readings, and monitor diagnostics to support if issues persist.

6. Frequently Asked Questions (FAQ)

What does reverse mount mean for this probe? The probe installs from the back side of the mounting bracket, useful when access from the front is limited.

Can I use it with standard 3300 XL extension cables? Yes. Total probe + extension length must match your Proximitor sensor (usually 5 m or 9 m systems).

Is the (CN) important? It indicates China market approvals for hazardous areas. Confirm it matches your site certification requirements.

How do I set the gap? Use a digital voltmeter at the Proximitor to set approximately -10 V DC (mid-range) for best linear response.

Is this New Surplus? New Original / New Surplus. Each probe is factory tested with traceability.

What calibration is it set for? Standard AISI 4140 steel target. Special calibrations are available for other materials.

What about warranty and availability? 1-year warranty. These specific configurations have varying stock—contact us with your full system requirements for lead time.
