Technical FAQs
1. What is the Bently Nevada 330103-00-05-90-02-00 used for?
It is used for measuring shaft vibration, radial displacement, and axial position in rotating machinery using non-contact eddy current sensing.
2. What makes the 330103 series different from 330101 and 330102?
The 330103 series uses an M10 × 1 metric thread without armor, while 330101 uses a 3/8-24 UNF thread and 330102 uses a 3/8-24 UNF armored design.
3. Is the 330103-00-05-90-02-00 an armored probe?
No. This model is a standard unarmored metric proximity probe.
4. What does the "00" option indicate?
The first 00 indicates a 0 mm unthreaded length configuration.
5. What does the "05" option represent?
The 05 option indicates a 50 mm overall case length.
6. What does the "90" cable option mean?
The 90 option specifies a 9.0-meter (29.5 ft) total cable length.
7. What type of connector does this probe use?
It uses a miniature coaxial ClickLoc™ connector with standard cable configuration.
8. Does this model include hazardous-area certification?
No. The final -00 suffix indicates no additional agency approval option.
9. What additional components are required for operation?
A complete system normally requires a compatible 3300 XL Extension Cable (when applicable) and a 3300 XL Proximitor Sensor.
10. Why choose a 9-meter cable proximity probe?
The longer cable configuration allows installation flexibility when the monitoring cabinet or Proximitor Sensor location is positioned away from the machine.
