Product Overview
Reliable condition monitoring of rotating machinery is essential for improving equipment safety, operational efficiency, and maintenance performance in industrial facilities. The Bently Nevada 330704-000-090-50-02-00 3300 XL 11 mm Proximity Probe is a high-precision non-contact displacement sensor designed for continuous monitoring of shaft vibration, radial displacement, and axial position in critical rotating equipment.
The probe is part of the 3300 XL 11 mm Proximity Transducer System, which uses eddy current sensing technology to measure the distance between the probe tip and the rotating shaft surface. This technology allows accurate vibration and position measurement without physical contact, providing excellent durability and long-term stability.
Compared with shorter cable versions, the 330704-000-090-50-02-00 features a 5-meter total length configuration, making it suitable for installations where the monitoring electronics are located farther away from the machine. With an 11 mm probe tip, M14 × 1.5 mounting thread, and industrial-grade construction, it is commonly used in turbines, compressors, generators, and other large rotating machinery systems.
