General

  • Manufacturer GE / Bently Nevada
  • Model 330103-00-16-50-12-RU
  • Condition New Original ready stock
  • Product Family 330103-00-16-100-12-RU,330103-00-16-90-12-RU,330103-00-16-80-12-RU
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Physical Calibration Update: Regularly check the gap voltage at the probe tip to ensure it is at the midpoint of the linear range (typically -9V to -11V DC).
  • System Upgrade Compatibility: Although the probe is a 3300 series, it is fully compatible with the newer 3500 series and Orbit 60 series monitoring systems (requires a 3300 XL preamplifier).
  • Connector Replacement: If the ClickLoc connector is damaged, it can be replaced in the field using the 3300 XL connector repair kit without replacing the entire 5-meter cable.
  • Environmental Protection Update: For models with RU (Russian certification), regularly check the integrity of the FluidLoc (12) liquid-resistant cable to ensure that the leak-proof standard continues to meet certification requirements.
  • Range Configuration: In the monitoring software (e.g., System 1), it needs to be configured to the standard range of the 8mm probe (200 mV/mil or 7.87 V/mm).
  • Target Material Programming: Calibration is performed by default for 4140 steel. If the target alloy is another alloy, the "Material Compensation Factor" needs to be set in the preamplifier or software.
  • Zero Point Setting: Manually enter the "Zero Position" offset in the monitoring system by mechanically adjusting the probe's installation depth.
  • Directional Programming: Define in the software whether the probe is installed horizontally or vertically to accurately synthesize the shaft center trajectory.
  • Radial Vibration Monitoring: Installed at the sliding bearings of steam turbines and centrifugal compressors to monitor the real-time vibration displacement of the journal.
  • Axial Displacement Protection: Installed on the rotor end face to monitor the wear of the thrust bearing and prevent axial collision between the rotor and stator.
  • High-permeability risk environments: Utilizing its FluidLoc (12) properties, it is applied to units where turbine oil, synthetic oil, or coolant pressure permeation exists.
  • Keyphasor measurement: Installed at the keyway of the shaft, it provides a reference for speed signals and vibration phases.
Description
The Bently Nevada 330103-00-16-50-12-RU 3300 XL 8 mm probe is part of the 3300 XL series Proximity Transducer System, providing precise, non-contact monitoring of rotating equipment such as steam turbines, compressors, and generators. It delivers an output voltage directly proportional to the distance between the probe tip and the conductive surface, enabling both static (position) and dynamic (vibration) measurements.

This probe features a miniature coaxial ClickLoc connector paired with FluidLoc cable, offering reliable signal transmission over a total length of up to 5.0 meters (16.4 feet). The probe case is constructed from AISI 303 or 304 stainless steel, while the tip is made of durable polyphenylene sulfide (PPS), ensuring resilience against high temperatures and harsh operating conditions. The nominal DC resistance of 8.73 ± 0.50 Ω supports stable sensor performance, and the probe operates across a wide temperature range of -52°C to +177°C (-62°F to +350°F).

The 330103-00-16-50-12-RU comes with an M10 x 1 threaded mounting and no armor, allowing flexible installation in tight spaces. When combined with the 3300 XL extension cable and Proximitor sensor, the system forms a complete monitoring solution that provides Keyphasor reference signals, speed measurement, and vibration analysis, enhancing predictive maintenance and early fault detection capabilities.

Compared to other 3300 XL probes, this model offers a compact 8 mm probe diameter with extended overall case length options of up to 160 mm, making it ideal for applications where space constraints exist without compromising measurement accuracy. Its robust design and high-temperature tolerance ensure consistent operation in demanding industrial environments.

Overall, the 330103-00-16-50-12-RU provides reliable, precise, and long-lasting performance, supporting critical monitoring and protection of high-value rotating machinery in a wide range of industrial applications.
