Eddy Current Measurement and Rotor Dynamics Features

The 330104-00-17-05-02-00 uses an eddy-current sensing principle to convert shaft position changes into proportional electrical signals. The 3300 XL system applies a defined scaling relationship between probe displacement and output voltage, allowing the Proximitor Sensor to process radial vibration and axial position signals.

The probe operates with a calibrated gap voltage range controlled by the connected Proximitor Sensor. During installation, technicians validate the electrical gap condition and typically verify the -10 VDC target reference used in Bently Nevada proximity measurement systems.

Furthermore, the probe supports rotor dynamics analysis by providing displacement signals required for shaft vibration monitoring, phase reference measurements, and machinery protection logic.

Frequently Asked Questions

Q: Does the 330104-00-17-05-02-00 require field calibration after replacement?
A: No. The 3300 XL system supports interchangeable probe, extension cable, and Proximitor Sensor combinations without bench calibration when technicians use matched system components.

Q: What type of signal does this proximity probe generate?
A: The probe provides an eddy-current measurement signal that the connected Proximitor Sensor converts into a proportional voltage output for vibration and position monitoring.

Q: Can this probe measure shaft vibration and axial position simultaneously?
A: The probe measures shaft displacement. System configuration determines whether the signal is applied for radial vibration, axial position, speed sensing, or Keyphasor phase measurement.

Field Installation Guidelines

• Install the probe using the M10 x 1 metric thread connection and maintain correct mechanical alignment with the target shaft surface.
• Keep the probe tip surface free from contamination because oil deposits or foreign material can affect eddy-current measurement accuracy.
• Route the coaxial cable away from high-current power conductors to reduce electrical interference.
• Connect the ClickLoc connector securely and maintain proper shielding practices according to the 3300 XL installation requirements.
• Verify the probe gap voltage through the connected Proximitor Sensor before placing the machinery protection channel into service.
• Confirm the target material condition because calibration characteristics depend on the specified conductive shaft material.
