The 330104-00-05-10-01-00 is a 3300 XL series 8mm interlocking armored eddy current proximity probe featuring a metric M10×1 full-thread casing and a total case length of 50mm. The hardware includes an integrated 1.0-meter stainless steel armored trailing cable terminated with a gold-plated ClickLoc coaxial connector complete with a physical connector protector. Its PPS engineering plastic tip and AISI 303/304 stainless steel body fully align with industrial fluid-proof and anti-corrosion specifications, serving as a foundational physical measurement node on steam turbines and high-power fan bearing housings to achieve complete transmission of shaft vibration and static displacement analog signals.
Physical Connector Protector and Gold-Plated ClickLoc Coupling
Highly Stable TipLoc Molding and Stainless Steel Case Casing
Highly Flexible Full-Thread Configuration and Strict System Interchangeability
The system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements. The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems, providing excellent mechanical configuration, linear range, accuracy, and temperature stability. All 3300 XL 8 mm proximity transducer systems provide this high level of performance and support interchangeability of components, eliminating the need to match or bench calibrate individual components. Each 3300 XL 8 mm Transducer System component is backward compatible and interchangeable with other non-XL 3300 series 5 mm and 8 mm transducer system components.

Thermal Power
Monitors shaft vibration of high, intermediate, and low-pressure rotors, as well as axial displacement at thrust bearings in large steam turbine-generator sets to ensure safe operation during grid load changes. Typical machinery includes steam turbines, generators, and large boiler feed water pumps.
Nuclear Power Plant
Provides real-time condition monitoring for the shaftlines of main turbine-generator units in the conventional island of nuclear power plants to prevent shaft misalignment. Equipment includes conventional island steam turbines, main generators, and condensate pumps.
Petroleum Refining
Measures thrust bearing wear of critical heavy oil hydrocracking units under extreme high temperature and pressure environments to prevent impeller-to-casing contact. Equipment includes cracking gas compressors, rich gas compressors, and high-pressure rich liquid pumps.
Steel & Metallurgical Industries
Monitors low-frequency shaft vibration of main blast furnace blowers to prevent severe vibrations caused by aerodynamic excitation during the smelting process. Equipment includes blast furnace axial blowers and converter gas recovery fans.
Hydroelectric Power
Installed at the guide bearings of hydroelectric generator units to monitor the radial runout (shaft swing) of large vertical or horizontal shafts. Equipment includes Francis/Kaplan hydro-turbine generator units and upper/lower/turbine guide bearings.
When using this armored probe, you must strictly regulate the official installation torque of its M10 threads using a torque wrench to prevent stainless steel case deformation, precisely adjust the insertion depth to align with the initial linear gap voltage of the Proximitor in the field, ensure the ClickLoc connector is fully locked into place with the physical connector protector properly engaged to absolutely isolate turbine oil ingress, and maintain a minimum physical bend radius of over 25.4 mm when routing its 1.0-meter trailing cable.
The Bently Nevada 330104-00-05-10-01-00 3300 XL 8mm is a high-precision, non-contact eddy current proximity probe configured for condition monitoring of fluid-film bearings in steam/gas turbines and centrifugal compressors, measuring axial displacement, radial vibration, and Keyphasor references. Featuring a 3/8-24 UNF threaded reverse mount configuration, this probe delivers high temperature resistance, high-accuracy linearity, and complete interchangeability, directly matching a 1-metre specification Proximitor sensor in field applications.
What is the Bently Nevada 330104-00-05-10-01-00 Proximity Probe?
It is a 3300 XL 8mm series eddy current proximity probe, which is a non-contact sensor. It is specially designed to measure micrometre-level dynamic vibration (such as shaft vibration) and static displacement (such as axial position) of rotating machinery shafts.
What is the working principle of the 330104-00-05-10-01-00 probe?
The high-frequency coil inside the probe tip generates a high-frequency electromagnetic field via the Proximitor. When the measured metallic shaft surface approaches this field, eddy currents are induced on the metal surface. The change in eddy currents alters the impedance of the Proximitor, converting it into a voltage signal proportional to the gap distance.
How to correctly install and use the 330104-00-05-10-01-00 probe in industrial fields?
Since this model is a reverse mount probe, it needs to be installed from the inside of the machine casing or fixed via a dedicated reverse mount bracket. During installation, it must be connected to a Proximitor sensor using an extension cable, and the Proximitor signal is then routed into a 3500 monitoring system for data acquisition.
What are the materials of the probe tip and case for 330104-00-05-10-01-00?
The probe tip material is Polyphenylene Sulfide (PPS), offering extreme chemical resistance and high thermal stability; the probe case material is AISI 303 or 304 Stainless Steel (SST).
What is the special design of the 330104-00-05-10-01-00 connector and how to protect it?
It uses a gold-plated ClickLoc locking coaxial connector, which is vibration-proof and anti-loosening. In humid or oily industrial environments, it must be used with a connector protector or heat-shrink tubing to prevent oil/water ingress from causing signal distortion.
