3300 XL 8 mm Proximity Probes

330103-00-22-50-12-05

Spare Part Number

PN330103-00-22-50-12-05

Product Information:

The Bently Nevada 330103-00-22-50-12-05 is an industrial-grade 8mm eddy current proximity probe from the 3300 XL series. As a core data acquisition component in condition monitoring and protection systems for large, critical rotating machinery such as industrial steam turbines, centrifugal compressors, and large fans, it is typically mounted robustly near hydrodynamic bearings and is designed for non-contact, high-precision measurement of rotor radial vibration, axial displacement, differential expansion, and critical phasor velocity signals.

In practical industrial circuits, the Bently Nevada 330103-00-22-50-12-05 features a high-strength polyphenylene sulfide (PPS) encapsulation at the front end, enabling it to withstand long-term high-temperature corrosion environments ranging from -52°C to +177°C under lubricating oil immersion. It must be used with a dedicated 5-meter system 3300 XL preamplifier (proximity sensor), which utilizes the principle of high-frequency electromagnetic eddy currents to convert minute gap changes between the probe tip and the surface of the 4140 steel journal being measured into a high signal-to-noise ratio voltage signal (standard sensitivity 7.87 V/mm).

Because the Bently Nevada 330103-00-22-50-12-05 has a built-in 5-meter cable, it can be directly connected to the dedicated preamplifier for the 5-meter system during field installation without the need for additional intermediate extension cables. This reduces electrical connection points and significantly lowers the probability of channel failures (absolutely prohibited) due to oil seepage or poor connector contact.

Overview Manuals Manuals Basic Info Ordering Information Spare Parts Maintenance

Features:

  • 3300 XL 8 mm Proximity Probes
  • 3300 XL 8 mm Proximity Transducer System
  • 330103 3300 XL 8 mm Probe, M10 x 1 thread, without armor
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.

Each 3300 XL 8 mm Transducer System component is backward compatible and interchangeable4 with other nonXL 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.

The 330103-00-22-50-12-05 Bently Nevada 3300 XL 8 mm Proximity Probes may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 3300 XL system is a cornerstone of the global turbine protection industry. This 5-meter-long, fully threaded, extra-long, oil-resistant, and explosion-proof probe is highly representative across various industrial automation supply chains and specialized spare parts distribution channels. During field project maintenance, the probe and its built-in 5-meter cable can typically be directly connected to the dedicated preamplifier of the 5-meter system (Note: Connecting an extension cable between the 5-meter probe and the 5-meter preamplifier is strictly prohibited; otherwise, it will cause changes in overall capacitance and distortion of the measurement output). This "direct connection" design effectively reduces the number of electrical intermediate joints inside and outside the cabinet, significantly reducing the likelihood of channel failures due to oil leaks, damage, or poor contact at joints (absolutely prohibited).
