📘 Product Profile: Bently Nevada 330780-50-00
🔧 Product Introduction
The 330780-50-00 is a high-precision eddy-current proximity probe, designed specifically for accurate and reliable displacement and vibration measurement in rotating machinery. This probe belongs to the 3300 XL series, a widely recognized family of proximity sensors used extensively in industrial machinery condition monitoring systems worldwide.
This probe operates by detecting the changes in the eddy currents induced by a conductive target (usually a rotating shaft), translating them into a voltage signal proportional to shaft position or vibration. The 330780-50-00 model features a rugged construction and is engineered to maintain stability and accuracy even in harsh environments.
The probe is often used as part of critical machinery protection and monitoring systems, ensuring early detection of mechanical faults such as shaft misalignment, rubbing, or imbalance, thereby minimizing downtime and avoiding catastrophic failures.
