The Bently Nevada 3300 XL 8mm reverse-mount proximity probe is an optimized eddy current sensor designed for industrial rotating machinery condition monitoring, specializing in non-contact measurement of vibration, shaft position, and rotational speed. It features an 8mm sensing element, standard 3/8-24 UNF threaded installation, a 2.0mm linear measurement range, and a calibrated sensitivity of 7.87 V/mm, ensuring consistent and accurate performance across diverse applications. The probe is built with high-temperature-resistant materials and a sealed structure, enabling reliable operation within a temperature range of -51°C to +177°C, even in oil-contaminated, high-vibration, and harsh industrial environments. Its corrosion-resistant housing and enhanced mechanical durability protect against physical damage and environmental wear, while advanced electromagnetic shielding suppresses interference from surrounding electrical equipment. Equipped with sealed ClickLoc connectors and FluidLoc technology, it ensures secure, leak-proof connections with 3300 XL extension cables and preamplifiers. Fully compatible with the 3300 XL monitoring system and compliant with API 670 standards, this probe is widely used in turbines, compressors, pumps, and large motors in oil & gas, power generation, and manufacturing industries. It supports predictive maintenance programs by providing real-time data on machine health, enabling early fault detection and reducing operational downtime.
