Bently Nevada 330101-00-39-15-02-05 8mm Proximity Transducer Probe

Product Description
The 330101-00-39-15-02-05 is a specialized eddy current probe from the Bently Nevada 3300 XL 8mm series, engineered for high-precision displacement and vibration monitoring in industrial turbomachinery. This non-contact sensor delivers critical data to machinery protection systems while withstanding harsh operating environments.

With a 3.9-inch unthreaded length and 1.5-meter total cable, the 330101-00-39-15-02-05 (3300 XL 8mm Probe) provides excellent linear range and temperature stability. Its probe tip, made from high-performance PPS, ensures a liquid-tight seal and chemical resistance to lubricants. The patented ClickLoc connector system maintains signal integrity, prevents accidental disconnection, and resists moisture ingress.

Technical Comparison: 3300 XL vs. Standard Probes

• Interchangeability: Compatible with both XL and standard 3300 extension cables; full XL accuracy requires XL components.

• Environmental Resistance: Thicker cable jacket and robust tip-to-cable bond for high-pressure environments.

• Signal Accuracy: Reduced temperature drift over the full operating range compared to legacy probes.

Frequently Asked Questions
Q: What is the significance of the 1.5-meter cable length?
A: This configuration ensures proper calibration when combined with extension cables and Proximitors for total lengths of 5 or 9 meters.

Q: Can this probe be used in submerged oil applications?
A: Yes. The PPS tip and stainless steel case are oil-tight and compatible with most industrial synthetic and mineral-based lubricants.
