製品紹介
The Bently Nevada 330904-07-15-05-02-00 3300 NSv Proximity Probe is a high-precision, non-contact displacement sensor engineered for use in rotating machinery vibration monitoring and shaft position measurement. It is part / the 3300 NSv series, which is designed for installations with restricted space and small machinery shafts.
This probe functions using the eddy current principle, detecting changes in the electromagnetic field generated near a conductive target surface. This allows it to provide highly accurate and linear measurement / both static shaft position and dynamic vibration signals. The 330904-07-15-05-02-00 model is commonly used in conjunction with Bently Nevada 3300 NSv Proximitor modules and extension cables, forming a complete monitoring system that adheres to API 670 machinery protection standards.
The compact design, combined with a robust stainless steel housing, makes this probe suitable for applications in turbines, compressors, pumps, and small motors, providing reliable early warning / mechanical issues, reducing downtime, and enhancing overall equipment reliability.
