Precision Condition Monitoring for Reliable Rotating Equipment Performance
The Bently Nevada 330101-02-12-10-02-05 3300 XL 8 mm Proximity Probe is a high-accuracy eddy-current sensor designed for continuous, non-contact measurement of shaft vibration, displacement, and position in critical industrial machinery. As part of the 3300 XL proximity transducer family, it delivers stable signal output, strong noise resistance, and long-term durability for demanding industrial monitoring applications.
This configuration is commonly associated with a 1.2-inch class probe case length and a 1.0-meter system cable assembly, making it suitable for standard-depth installations in turbines, compressors, and rotating equipment where stable mechanical fit and measurement precision are essential. It is engineered to integrate seamlessly into predictive maintenance systems for real-time machine health diagnostics.
Built with stainless steel housing and a PPS (Polyphenylene Sulfide) sensing tip, this probe is designed for harsh industrial environments with high vibration, temperature variation, and continuous operation requirements.
