Quick Detail

Description

The 3300 XL 11 mm Proximity Probe (330703-000-100-10-02-05) is a high-precision, non-contacting transducer specifically designed for advanced vibration and displacement monitoring in industrial automation and rotating machinery. With an output sensitivity of 3.94 V/mm (100 mV/mil), this probe enables accurate measurement of axial (thrust) positions, ramp differential expansion, rod positions, and phase reference signals on fluid film bearing machines. The large 11 mm probe tip allows a significantly longer linear range than standard 8 mm 3300 XL probes, improving signal reliability and dynamic response across demanding operating conditions.

This probe features a robust M14 x 1.5 threaded case with a maximum thread engagement of 21 mm, an overall case length of 100 mm, and a total cable length of 1.0 meter (3.3 feet). The probe is equipped with a Miniature coaxial ClickLoc connector, providing secure electrical connections, while 99.9% braided copper shielding ensures minimal signal interference. Designed for harsh environments, the 3300 XL 11 mm Proximity Probe carries IP67-rated protection against dust and water and operates in a temperature range of -40°C to +85°C, ensuring durability and reliability in industrial automation systems.

Compatible with upgraded 3500 Monitoring Systems and designed to replace legacy 7200-series 11 mm and 14 mm transducers, the 3300 XL 11 mm Probe requires complete system component replacement during upgrades. Its gold-plated brass ClickLoc connectors, TipLoc molded probe tip, and CableLoc design allow secure connections with a 330 N (75 lb) pull strength, while optional FluidLoc cables prevent oil leakage and connector protectors enhance performance in humid environments. The included locknut with pre-drilled safety wire holes adds an extra layer of installation safety.

Applications
