Product Overview
The Bently Nevada 330105-02-12-20-02-00 is a reverse mount proximity probe from the 3300 XL 8 mm series. It forms part / a proximity transducer system designed to monitor vibration and position in fluid-film bearing machines. It connects with a matching extension cable and Proximitor sensor to provide precise, linear output proportional to the gap between the probe and shaft surface.

FAQs
Q1: What is the primary use / this probe?
A1: It’s mainly used for monitoring vibration and shaft position in rotating machinery with reverse mount constraints.
Q2: Can it be used with older 3300 systems?
A2: Yes, it is backward compatible with non-XL 3300 8 mm and 5 mm systems.
Q3: Is it suitable for high-temperature environments?
A3: Yes, the standard version supports up to +177°C. For higher temperatures, an Extended Temperature Range (ETR) version is available.
Q4: What mounting thread is used on this model?
A4: This version uses a 3/8-24 UNF mounting thread.
Q5: Does it come with armor protection?
A5: Armor is not available on reverse-mount probes like this model.
Q6: Is a special tool required to tighten the connector?
A6: No, ClickLoc connectors are finger-tightened and provide a positive lock when clicked.
Q7: Can I use this probe in hazardous environments?
A7: Yes, it has CSA, ATEX, and IECEx certifications for hazardous locations.
Q8: How does the FluidLoc cable help?
A8: It prevents oil and other fluids from leaking through the cable in sealed machine applications.
Q9: What is the total system weight?
A9: This model weighs approximately 0.646 kg for the 2-meter configuration.
Q10: What is the probe’s output sensitivity?
A10: 200 mV/mil with ±5% accuracy over its linear range.
