Product Introduction
The 330180-52-CN is a 3300 XL 8 mm proximity probe, specifically the probe component of the Bently Nevada 3300 XL series eddy current probe system. This model features a 5/8-12 UNF threaded case with a standard length and is designed for non-contact measurement of shaft vibration, position, and eccentricity. The “-CN” suffix indicates a connectorized version, allowing for field replacement of the extension cable without removing the probe from the machine. It is precision-engineered to deliver superior linear range, temperature stability, and long-term reliability in demanding industrial environments.

Application Scenarios
Radial Vibration Monitoring: Installed in bearing housings of steam turbines, gas turbines, compressors, and large pumps to measure shaft radial vibration for machinery protection and predictive maintenance.
Thrust (Axial) Position Monitoring: Used to monitor axial shaft position, providing critical data to prevent thrust bearing overload and rotor-to-stator contact.
Shaft Eccentricity Measurement: Deployed on large turbine rotors to measure shaft bow during startup and coast-down phases, ensuring safe operating conditions.
Differential Expansion Monitoring: Employed in combination with complementary sensors to measure relative thermal expansion between rotor and casing in steam turbines.
Field Service Flexibility: The connectorized design (-CN) simplifies maintenance by enabling replacement of damaged extension cables without disturbing the probe’s mounting position or requiring recalibration, making it ideal for field service applications in power plants, oil and gas facilities, and chemical plants.
