製品紹介
The Bently Nevada 330901-00-12-05-02 3300 NSv Proximity Probe is a precision non-contact sensor specifically engineered for shaft vibration and axial position measurements in small and medium-sized industrial machines. As part / the renowned Bently Nevada 3300 NSv (Narrow Signal Version) series, it delivers highly accurate displacement and vibration monitoring where space constraints or small shaft diameters make standard probes impractical.
This probe operates on the eddy current principle, generating a magnetic field to measure the exact distance between the probe tip and the rotating shaft surface. It forms a complete proximity measurement system when used with a 3300 NSv Proximitor Sensor and a coaxial extension cable. The system provides a linear output proportional to shaft movement or vibration, enabling accurate machinery diagnostics and protection.
Designed for harsh industrial environments, the 330901-00-12-05-02 /fers excellent imm台y to temperature fluctuations, electromagnetic interference, and oil contamination. It complies fully with API 670 standards, ensuring compatibility with global vibration and condition monitoring systems.
