High-Stability Industrial Sensing for Critical Rotating Equipment Protection
The Bently Nevada 330101-30-49-10-02-05 3300 XL 8 mm Proximity Probe is a high-precision eddy-current sensor engineered for continuous, non-contact measurement of shaft vibration, radial displacement, and position in industrial rotating machinery. As part of the proven 3300 XL proximity transducer system, it delivers consistent signal integrity, strong EMI resistance, and long-term reliability in harsh operating environments.
This configuration (30-49-10-02-05) is typically associated with a 3.0-inch unthreaded length, 4.9-inch case length, 1.0-meter system cable, ClickLoc connector, and certified industrial configuration option, making it suitable for deeper installation requirements in turbines, compressors, and heavy-duty rotating equipment. The “30-49” geometry is often selected for applications requiring extended probe reach and mechanically reinforced mounting stability in high-vibration machinery zones.
Built with stainless steel housing and a PPS sensing tip, the probe ensures long-term dimensional stability and accurate signal output even under continuous industrial stress.
