Product Introduction
The Bently Nevada 330906-02-12-10-02-CN 3300 NSv Reverse Mount Probe is a precision-engineered non-contact eddy current sensor designed for accurate shaft vibration and displacement measurement in compact and reverse-mounted installations. As part of the Bently Nevada 3300 NSv (Narrow Side View) series, this probe is optimized for small machines and restricted areas where traditional forward-mount probes cannot be conveniently installed.
This model utilizes reverse-mount configuration, meaning the probe is inserted from the rear of the mounting surface, ensuring optimal protection from contaminants, oil, and physical impact. The probe works seamlessly with the 3300 NSv Proximitor Sensor to provide linear, high-fidelity output for both static and dynamic measurements.
Engineered with high-grade stainless steel housing, it delivers excellent resistance to corrosion and industrial pollutants. It operates reliably in harsh conditions involving vibration, oil exposure, and elevated temperatures. This makes it particularly suitable for turbines, compressors, motors, gearboxes, and pumps—critical components in the oil & gas, petrochemical, and power generation industries.
