Precision Monitoring Solution for Critical Rotating Equipment
The Bently Nevada 330101-00-65-10-11-00 3300 XL 8 mm Proximity Probe is a high-reliability eddy-current sensor designed for continuous measurement of shaft vibration, radial displacement, and position in industrial rotating machinery. As part of the proven 3300 XL series, it delivers stable performance, excellent signal integrity, and long-term durability in demanding industrial environments.
This configuration (…11-00 variant) is commonly associated with a 1.0-meter system cable length and a standard configuration without additional agency-specific certification options, making it a versatile choice for general-purpose turbomachinery monitoring applications. The probe operates without physical contact, ensuring accurate measurement while eliminating mechanical wear and extending service life.
Built with stainless steel housing and a PPS sensing tip, it is engineered for harsh environments where vibration, temperature fluctuations, and contamination are common.
