Heavy-Duty Non-Contact Monitoring for Large Turbomachinery
The Bently Nevada 330876-01-90-00-00 3300 XL 50 mm Eddy-Current Probe is a premium industrial sensor designed for highly accurate non-contact measurement of shaft displacement, differential expansion, and rotor position in large rotating machinery. As part of the 3300 XL 50 mm Transducer System, this probe is specifically engineered for applications where standard 8 mm or 25 mm probes do not provide sufficient measurement range.
Built to withstand demanding industrial environments, this large-diameter probe delivers exceptional stability, durability, and long-term performance. It is widely installed in steam turbines, hydro turbines, large compressors, and generator systems that require continuous machinery protection and precise condition monitoring.
Its advanced eddy-current technology helps operators detect mechanical abnormalities early, reducing unplanned downtime and extending equipment life.
