Bently Nevada 330101-30-63-10-02-00 3300 XL 8 mm Proximity Probe with API 670 Compliance and Miniature ClickLoc Connector for Eddy Current Displacement Sensing

If you break it down, the configuration isn’t complicated, but in real field work people usually just recognize the option codes rather than reading everything literally:

• -30 refers to about 3.0 inches of unthreaded probe length
• -63 indicates a 6.3-inch overall case length
• -10 means 1.0 meter total cable length
• -02 comes with a miniature coax ClickLoc connector, the quick-connect type commonly used in 3300 XL systems
• -00 is the standard version without additional agency approvals or special regional certifications

So overall, it’s a pretty “typical industrial configuration” probe — not customized, but widely used in rotating machinery setups.

probe → 330130 extension cable → 3300 XL Proximitor Sensor

From there, the Proximitor conditions the eddy current signal and sends it into a monitoring system such as the Bently Nevada 3500 platform, often through modules like the 3500/40M monitor card. Once it reaches that stage, the raw displacement and vibration data becomes usable for continuous machinery protection and condition monitoring.

You’ll commonly see it in:

• steam turbine vibration monitoring
• gas turbine displacement measurement
• centrifugal compressor protection systems

It’s widely used in power generation and petrochemical plants, especially where API 670 compliance is required.

Function-wise, it handles shaft vibration, axial displacement, and slow mechanical movement tracking. In real terms, it’s basically one of the key sensors keeping critical rotating assets under control.

In most installations, especially where API 670 machinery protection is required, this kind of 3300 XL proximity probe is fully accepted as part of the safety chain. It’s used because it’s reliable for continuous monitoring in critical rotating equipment, not because it makes decisions. So in practical terms: the probe senses what’s happening, while the protection system decides whether the machine needs to be shut down.

• 1.0 meter unarmored proximity cable
• industrial-grade insulation suitable for oil, vibration, and general harsh environments
• terminated with a gold-plated ClickLoc coaxial connector

The ClickLoc design is widely used in Bently Nevada 3300 XL systems because it’s quick to install and holds up well under vibration. In practice, it helps reduce signal loss and avoids accidental loosening in long-term operation, especially in high-vibration machinery areas.
