The Bently Nevada 330104‑00‑03‑50‑01‑05 is a high‑precision eddy‑current proximitor sensor designed for continuous vibration and shaft displacement monitoring in industrial rotating machinery. Part of the renowned 3300 XL Proximitor Sensor Series, this model combines extended reach with high-resolution measurement capability.
This variant features a 3 mm sensing gap (code “03”), a 50 m integral cable (code “50”), a standard industrial connector type 1 (code “01”), and an enhanced output configuration (code “05”). Its extra-long cable length allows flexible installation in large machinery plants, turbine halls, or compressor stations where sensor heads must be located at a distance from monitoring modules.
The sensor operates on eddy-current sensing technology, creating a magnetic field at the sensor tip. Variations in proximity to the conductive target (typically the rotor shaft) induce voltage changes proportional to displacement. These signals are fed to monitoring systems to detect vibration trends, rotor misalignment, or early mechanical failures.
