      Information

      Overview Manuals Common Applications Product Precautions
      The 330104-05-10-50-02-05 is a 3300 XL series 8mm high-precision non-contact eddy current proximity probe manufactured by Bently Nevada, USA. Featuring a standard M10×1 metric thread structure with heavy-duty stainless steel armor protection, it serves as a core sensing component in condition monitoring systems to provide continuous online measurement of radial shaft vibration and axial displacement on industrial rotating machinery.
        • Integrated 5-Meter Cable for a Zero-Joint System
        • Supports calibration-free interchange of the same model
        • Full Compliance with API 670 Standard
      The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The integrated 3300 XL 8 mm 5-meter probe configuration fully complies with the American Petroleum Institute’s (API) 670 Standard for mechanical configuration, linear range, accuracy, and temperature stability when connected directly to its corresponding Proximitor.

      All 3300 XL 8 mm proximity transducer systems provide this level of performance and support complete interchangeability across compatible 3300 XL components, eliminating the need to match or bench calibrate individual units. 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 on the main bearings of steam turbine-generator sets in large supercritical thermal power plants to continuously measure shaft vibration and Keyphasor (speed) to ensure grid stability.

      Nuclear Power
      Used for bearing axial and radial condition monitoring of conventional island steam turbines and massive reactor coolant pumps (RCPs) to guarantee nuclear power safety.

      Hydroelectric Power
      Used for measuring unit swing (radial vibration) and main shaft axial displacement in large vertical/horizontal hydro-generator units to cope with water hammer and sudden load changes.

      Petrochemical & Refining
      Used for axial displacement monitoring of large centrifugal compressors and high-pressure pumps in catalytic cracking and hydrocracking units to prevent catastrophic collisions between the rotor and stator.

      Iron & Steel / Metallurgy Industry
      Used for vibration monitoring of blast furnace large blowers (TRT units) and heavy-duty gearboxes in hot rolling mills. The stainless steel armor effectively resists metal splashes and high temperatures.
       When using the 330104-05-10-50-02-05 probe, observe these critical points. Strict control of the tightening torque within 5.6 N·m is required during installation. Use a voltmeter to precisely adjust the initial installation gap voltage to approximately -10 Vdc at the linear midpoint. Since this configuration features an integrated 5-meter armored cable, it must never be cut or randomly altered. Maintain a minimum bend radius of 30.5 mm during routing. This protects the internal coaxial impedance and preserves the system's calibration-free interchangeability.

      Technical notes

      The 330104-05-10-50-02-05 is a 3300 XL series 8mm metric forward-mount proximity probe. When connected to a matching 3300 XL Proximitor Sensor, 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. It delivers a standard 2.0 mm (80 mils) linear range with a scale factor of 7.87 V/mm (200 mV/mil).Featuring an M10×1 threaded case with a 100 mm overall case length and a 50 mm unthreaded length, this specific configuration integrates an elongated 5.0-meter (16.4 feet) standard coaxial cable enclosed in protective stainless steel armor, terminating in a miniature coaxial ClickLoc connector. Certified with multi-agency regulatory and hazardous area approvals (-05), the probe operates reliably within a temperature range of -51 °C to +177 °C. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements.

      FAQ View All FAQ

      • What is the 330104-05-10-50-02-05?
        It is a 3300 XL series 8mm metric forward-mount eddy current proximity probe manufactured by Bently Nevada, USA, specifically configured with a stainless steel armored cable.
      • What is the operating principle of the 330104-05-10-50-02-05?
        It operates on the eddy current principle. When the probe tip is near a metallic shaft surface, a high-frequency electromagnetic field is generated. When connected to a Proximitor sensor, it converts the distance variations between the probe tip and the target surface into a proportional voltage signal.
      • How to correctly install the 330104-05-10-50-02-05?
        The probe is typically threaded into a machine casing or mounting bracket from the front using its M10×1 threads. During installation, a voltmeter should be used to monitor the Proximitor sensor's output gap voltage (typically adjusted to around -10 Vdc, the midpoint of the linear range) before locking the mounting nut.
      • What is the maximum tightening torque when installing the 330104-05-10-50-02-05?
        The recommended maximum tightening torque is 5.6 N·m (50 in·lbf). Exceeding this value may damage the threads or the probe case.
      • What is the purpose of the armor on the 330104-05-10-50-02-05?
        The stainless steel armor covers the outer layer of the cable, providing excellent mechanical protection for the internal coaxial cable. It prevents the cable from being cut, abraded, crushed, or damaged by metal debris in harsh industrial environments.
