The 330101-00-08-05-02-05 corresponds to a specific configuration of the Bently Nevada 3300 XL 8 mm Proximity Probe. It is a non-contact eddy current sensor used for measuring shaft vibration and position.
One 3300 XL 8 mm probe (this component)
One 3300 XL extension cable (4.5-meter required for a 5-meter system)
One 3300 XL Proximitor Sensor
The standard 3300 XL 8 mm 5-meter system fully complies with the American Petroleum Institute’s (API) 670 Standard for mechanical configuration, linear range, accuracy, and temperature stability.
All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, 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. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space.

Thermal Power
Installed inside the high and low-pressure main shaft bearing housings of 300MW/600MW/1000MW supercritical steam turbine generator sets to continuously capture relative shaft oil film vibration.
Nuclear Power
Used for non-contact precision tracking of axial thermal growth displacement on conventional island large steam turbine main bearings and reactor secondary circuit large feedwater pumps in nuclear power plants.
Petroleum Refining
Used for rotor axial thrust monitoring of large rich gas compressors and heavy oil catalytic cracking turbine trains in crude distillation units to prevent rotor collision.
Coal Chemical
Used at the main bearings of syngas compressors and carbon dioxide compressors in large fertilizer plants to monitor shaft runout within intrinsically safe explosion-proof environments.
Iron, Steel and Metallurgy Industry
Used for non-contact relative shaft vibration monitoring of blast furnace blower trains, large sintering exhaust fans, and blast furnace Top Pressure Recovery Turbine (TRT) unit main shafts.
Hydroelectric Power
Used at the upper guide, lower guide, and thrust bearing housings of hydro-generator units to precisely capture the radial runout of large-diameter rotors or act as a keyphasor to measure speed.
When using the 330101-00-08-05-02-05 probe, strict attention must be paid to cable protection, precise installation, and connector maintenance. First, avoid over-bending or twisting the armored cable to prevent internal coaxial wire damage.
Second, accurately adjust the initial gap during installation, and reliably secure and ground the stainless steel armor to eliminate mechanical wear and high-frequency electromagnetic interference.
Finally, keep the miniature coaxial connectors meticulously clean and dry, and use a dedicated torque wrench for proper tightening while strictly prohibiting brute-force pulling, thereby ensuring long-term stable system operation.
This system is a Bently Nevada 3300 XL 8mm Proximity Transducer System. By outputting a voltage signal directly proportional to the distance between the probe tip and the conductive surface, it can precisely measure both the static axial position and dynamic radial vibration of rotating machinery. It is widely applied in fluid-film bearing machine monitoring, Keyphasor reference, and speed measurements. The system strictly complies with the API 670 standard. Its core component, the 330101-00-08-05-02-05 proximity probe, features a 3/8-24 UNF fully threaded housing (0.8 inches in length) and is designed as an unarmored configuration. It is equipped with a 0.5-meter standard cable with gold-plated ClickLoc connectors (which pairs with a 4.5-meter extension cable to form a standard 5-meter system). Furthermore, the probe integrates proprietary TipLoc molding technology and a CableLoc cable grip design, which significantly enhance the probe tip strength and cable pull-out resistance, ensuring long-term structural integrity and signal stability in harsh industrial fields.
It is a 3300 XL series 8 mm non-contact eddy current proximity transducer probe assembly manufactured by Bently Nevada.
How to properly install and use products like 330101-00-08-05-02-05 on site?
It must be rigidly secured via a dedicated bracket inside the bearing housing to face the shaft surface, adjusting the threads to set the initial gap before connecting to a Proximitor.
What is the core operating mechanism of 330101-00-08-05-02-05?
Utilizing the eddy current induction principle, the probe tip coil generates a high-frequency alternating magnetic field, causing impedance changes when the metallic shaft approaches to convert into displacement voltage signals.
What type of connector is used at the tail of 330101-00-08-05-02-05?
The probe is equipped with an original Bently Nevada single-pin miniature coaxial ClickLoc connector featuring anti-vibration self-locking properties.
What is the primary monitoring purpose of 330101-00-08-05-02-05 inside a plant?
It is primarily used to capture micron-level shaft radial vibration, static axial displacement of large turbine rotors, or act as a keyphasor sensor to measure precise speeds.
