Features:

  • Stainless steel probe body with PPS tip and Viton sealing ensures durability in harsh industrial environments.
  • 3300 XL system compatibility enables accurate vibration, position, speed, and Keyphasor measurement functions.
  • API 670 compliant design supports high precision, linear response, and stable temperature performance in rotating machinery monitoring.
Bently Nevada 330103-02-08-50-11-00 is a 3300 XL 8 mm proximity probe designed for use in advanced machinery condition monitoring systems. It forms part of a complete proximity transducer system that includes the probe, extension cable, and Proximitor sensor. The system provides accurate measurement of shaft displacement and vibration by generating a voltage signal proportional to the distance between the probe tip and conductive target surface. It is widely applied in rotating machinery such as turbines, compressors, and pumps.

The probe is constructed with AISI 303 or 304 stainless steel to ensure mechanical strength and corrosion resistance in industrial environments. Bently Nevada 330103-02-08-50-11-00 also integrates a PPS probe tip and Viton O-ring sealing material to maintain stability under demanding operating conditions. Electrical performance is supported by a nominal DC resistance of 8.73 ± 0.50 Ω, ensuring consistent signal response during continuous monitoring applications.

Bently Nevada 330103-02-08-50-11-00 supports a 5.0-meter cable length option and uses a miniature coaxial ClickLoc connector system with FluidLoc cable for secure installation. The probe operates across an extreme temperature range from -52°C to +177°C, making it suitable for harsh industrial and high-temperature environments. Its full compatibility with the 3300 XL system and backward compatibility with earlier 3300 series components allows flexible integration into both new and existing machinery monitoring installations.

The 330103-02-08-50-11-00 Bently Nevada 3300 XL 8 mm Proximity Probe may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

  • Gas Turbine Radial Vibration Measurement: Installed on the bearing housing inside large, heavy-duty gas turbines, it accurately captures the radial dynamic vibration trajectory of the shaft during operation using an orthogonal method (X-Y probe).
  • Centrifugal Fan Axial Displacement Monitoring: Widely used in large centrifugal induced draft fans in metallurgy and power plants, specifically designed to lock the static axial movement of the brake rotor, preventing physical collisions between the impeller and the casing.
  • Keyphase Measurement for Large Industrial Gearboxes: Installed as a keyphasor on the input/output shaft side of the gearbox, it provides a speed reference signal per revolution via the keyway or protrusion on the shaft.
  • Swing Analysis of Hydropower Generator Sets: Used in large vertical or horizontal hydropower generator sets in hydropower stations to monitor the large-amplitude, low-frequency swing of the main shaft over long periods, providing crucial data for dynamic balancing of the unit.
  • Real-time Gap Voltage Monitoring: By using the output DC bias voltage, operators can visually diagnose whether the initial physical installation distance between the probe and the measured shaft surface is correct.
  • Physical Crosstalk Identification: In conjunction with the 3500 system diagnostic software, it can effectively identify and eliminate electromagnetic crosstalk caused by two probes being installed too close together.
  • Physical Defect and Electrochemical Inhomogeneity Diagnosis: Utilizing the probe's high-sensitivity output, it can diagnose mechanical runout on the measured shaft surface and electrochemical runout caused by material inhomogeneity.
  • Loop Integrity Self-Check: In conjunction with a preamplifier, it can perform self-diagnosis of faults such as open circuits or short circuits. When the cable is damaged or the probe head is broken, the system will immediately trigger a sensor fault (Not OK) alarm.
  • Intrinsically Safe and Explosion-Proof Dual Certification: Obtained ATEX/IECEx international explosion-proof certification, allowing safe use in Zone 1 hazardous areas containing explosive gas mixtures such as oil and natural gas.
  • North American Hazardous Area Standards: Meets North American safety standards such as CSA and FM, and complies with extremely stringent industrial explosion-proof classifications including Class I, Division 1, Groups A, B, C, and D.
  • Global Major Market Access: Holds local explosion-proof compliance certificates from multiple countries and regions, including NEPSI (China) and TR CU (Customs Union), ensuring seamless procurement and market access for multinational projects.
  • High-Level Mechanical Protection and RoHS: The probe head and overall cable structure meet high-level industrial waterproof and dustproof certifications, and the production process adheres to RoHS environmental directives.
