Product Introduction
The Bently Nevada 330908-00-28-10-01-CN 3300 NSv Proximity Probe is a high-performance, non-contact vibration and displacement measurement sensor engineered for precise monitoring in compact machinery applications. As part of the Bently Nevada 3300 NSv (Narrow Side View) Proximity Transducer System, this probe provides reliable measurement of shaft vibration and position in environments where standard probe installations are not feasible due to space constraints.
Using eddy current sensing technology, the 330908-00-28-10-01-CN detects the proximity of a conductive surface such as a rotating shaft, offering highly linear, repeatable output signals that are proportional to the measured displacement. This probe is designed for integration with the 3300 NSv Proximitor Sensor and an appropriate extension cable to form a complete transducer system.
Engineered for durability, stability, and long-term reliability, this probe is optimized for use in harsh industrial environments, including turbines, compressors, and pumps in the oil, gas, and power generation industries. It fully complies with API 670 machinery protection standards, ensuring precise monitoring of critical rotating equipment.
