The Bently Nevada 3300 XL series represents the industry standard for eddy current proximity transducer systems, specifically engineered for vibration monitoring and position measurements on fluid-film bearing machines. This high-precision system consists of a 3300 XL probe, an extension cable, and a Proximitor™ sensor, designed to provide a linear voltage output proportional to the distance between the probe tip and the observed conductive target. Key technical advantages include superior scale factor stability and interchangeability across a wide temperature range, significantly reducing the need for individual component calibration. Designed to withstand harsh industrial environments, the 3300 XL 8mm and 5mm systems offer advanced RFI/EMI immunity and are fully compatible with Bently Nevada 3500 and 3300 monitoring racks. Whether monitoring radial vibration, axial thrust, or phase reference (Keyphasor™), this series delivers the sub-micron resolution essential for critical machinery protection and predictive maintenance.
