Product Introduction
The Bently Nevada 330180-A51-B00 is a part of the 3300 XL 8mm Proximitor Sensor series, renowned for its reliability and performance in critical industrial vibration monitoring and machinery protection systems. Developed by GE’s Bently Nevada division, this sensor is engineered to provide highly accurate, non-contact displacement measurements in demanding environments such as power generation, oil and gas, and heavy manufacturing.
The “A51” suffix in this model designates a specific configuration related to system length (commonly 5 meters) and potentially special certification or market-specific variants. The Proximitor sensor works in conjunction with proximity probes and extension cables to monitor the dynamic and static position of rotating shafts and machinery components.
