製品紹介
The Bently Nevada 330908-00-08-05-02 3300 NSv Proximity Probe is a high-precision, non-contact eddy-current sensor designed to monitor shaft vibration, dynamic displacement, and rotor position in critical rotating machinery. As part / the 3300 NSv (Narrow Side-view) series, it is engineered for environments where space is limited but high measurement accuracy is required. The probe features a durable stainless-steel housing and integrated EMI shielding to ensure stable performance under harsh industrial conditions, including extreme temperatures and high electromagnetic interference. This makes it an essential component for predictive maintenance programs, machine protection systems, and continuous operational monitoring in turbines, compressors, generators, and industrial pumps.
