The Bently Nevada 330105-XX-XX-10-02-00 (157310-07) is part of the well-known 3300 XL 8 mm reverse mount proximity probe family, designed to monitor shaft vibration and displacement in rotating machinery with high accuracy and reliability. Its reverse mount design makes it particularly suitable for installations where conventional forward mounting is not feasible due to space restrictions or design limitations.

Utilizing eddy current technology, the probe provides a precise voltage signal proportional to the distance between the probe tip and the target shaft surface. With its 1-meter total cable length and robust stainless-steel construction, it ensures consistent performance in harsh environments such as turbines, compressors, pumps, and large industrial motors. The probe is fully compatible with the Bently Nevada 3300 XL monitoring system, making it an integral part of machine protection and condition monitoring solutions.
