Meta Description
Get the engineering breakdown of the Bently Nevada 330101-00-70-10-02-CN 3300 XL 8 mm proximity probe. Read about dimensions, thread specs, and field tips.
Main Body
When calibrating a high-speed compressor’s radial vibration path, choosing a probe with incorrect thread depth can bottom out the tip or leave it floating outside its linear range. The Bently Nevada 330101-00-70-10-02-CN belongs to the industry-standard 3300 XL 8 mm Proximity Transducer series. This non-contact eddy-current sensor is designed for continuous machinery protection, measuring static shaft position (thrust) and dynamic shaft vibration (radial) on fluid-film bearing machinery.

By utilizing the standard 7.87 V/mm (200 mV/mil) incremental scale factor, this probe integrates seamlessly with standard 3300 XL Proximitor sensors. The ClickLoc coaxial connector provides a secure connection that clicks into place finger-tight, preventing the signal degradation commonly caused by over-torqued connections.
Do you have applications running through harsh chemical environments or high-pressure steam paths? This probe is not recommended for direct contact exposure in high-pressure steam casings without an appropriate dry-well or sealing gland. Over-tightening the 3/8-24 threads beyond the recommended 163 N·m limit can warp the internal sensor coil housing, permanently throwing off the scale factor.
Well, technically, the probe tip operates reliably up to 177 °C, but thermal cycling can induce slight drift in physical clearances. For standard gas and steam turbine installations, this 7.0-inch unarmored probe is a critical warehouse item. Keeping a dedicated backup probe on-site is a highly practical insurance policy against mechanical shear during turnaround periods.
