4. Product Introduction

The Bently Nevada 330195-02-12-05-05 is a 3300 XL Extended Temperature Range (ETR) 8 mm reverse mount proximity probe with 3/8-24 UNF threads. It measures shaft vibration and position in high-temperature environments.

The ETR design extends operating temperature capability for demanding applications like gas turbines and high-heat machinery. Reverse mount configuration simplifies installation in confined spaces. This probe delivers the same reliable eddy current performance as standard XL units but with better thermal tolerance.

5. Troubleshooting Quick Reference

Symptom Possible Cause Relevance to this Part Quick Check Method Recommendation
No output voltage Probe not connected High Measure DC voltage at Proximitor Verify ClickLoc connections and seating
Readings out of range Incorrect gap setting High Set gap for -8 to -12 V DC typical Adjust probe insertion depth
Signal noise Cable damage or EMI Medium Inspect cable for abrasion Replace extension cable if needed
Over-temperature error Exceeded ETR limits Low Monitor probe case temperature Confirm application temperatures
Probe leak Improper installation torque Low Check for fluid around mounting Torque to spec and use thread sealant if required

Contact support with installation details, measured gap voltage, and system configuration for persistent problems.

6. Frequently Asked Questions (FAQ)

What makes this an ETR probe? Extended Temperature Range construction allows higher continuous operating temperatures than standard 3300 XL probes.

Is it compatible with standard extension cables? Yes. Use with appropriate 3300 XL extension cables to reach total system length for your 5 m Proximitor.

Why reverse mount? It installs from inside the machine case, ideal when external access is difficult.

How do I install it? Thread into the machine case, set proper gap to target, and connect ClickLoc cable. Follow torque specifications to maintain seal.

Is this New Surplus? New Original / New Surplus with full factory traceability.

What target material is it calibrated for? Standard AISI 4140 steel. Contact us for other material calibrations.

What about warranty and availability? 1-year warranty. ETR probes have specific lead times—confirm stock for this exact configuration.
