Product Introduction
The Bently Nevada 330910-00-05-02-00 3300 NSv Proximity Probe is a high-precision, non-contact displacement transducer designed for continuous monitoring of industrial rotating machinery. Part of the 3300 NSv Series, this probe provides accurate vibration, position, and displacement measurement, enabling early detection of machinery issues and ensuring reliable machine protection.
Unlike standard proximity probes, the 3300 NSv series is optimized for high-speed, high-resolution measurement, delivering excellent performance in monitoring small to medium shaft diameters and slow to fast rotating equipment. Utilizing eddy current sensing technology, the probe converts shaft motion into a proportional voltage output, which is processed by the corresponding NSv signal conditioning system.
This model meets API 670 requirements for machine condition monitoring and protection. Its compact and rugged design, combined with a hermetically sealed stainless steel body, ensures durability in harsh industrial environments including oil, moisture, dust, and electromagnetic interference. The 330910-00-05-02-00 is widely used in turbines, generators, compressors, pumps, and motors, providing reliable real-time data for protection systems and predictive maintenance programs.
