The Bently Nevada 330104-05-18-50-02-00 is a precision proximity probe designed for continuous monitoring of critical industrial rotating machinery. It measures shaft displacement and vibration, providing AC voltage output that seamlessly integrates with 3300 series machinery protection systems.
This model is particularly suited for high-speed, heavy-duty applications requiring a wide measurement range and robust mechanical construction. Its ability to detect early mechanical issues such as rotor misalignment, imbalance, eccentricity, and bearing wear makes it ideal for predictive maintenance programs. The probe’s rugged design ensures reliable performance in environments with high vibration, dust, and temperature variation.
