Eddy-Current Measurement and Rotor Dynamics Monitoring

The 330104-00-10-10-02-00 uses an eddy-current sensing principle to detect shaft displacement without mechanical contact. Therefore, the probe provides dynamic vibration and static position signals required by turbine supervisory instrumentation (TSI) systems.

The probe maintains a nominal scale factor of 7.87 V/mm, which allows the connected Proximitor Sensor to convert gap changes into proportional voltage outputs. In addition, correct gap voltage validation supports accurate probe installation, with typical Bently Nevada systems using approximately -10 VDC gap voltage targets for normal operating alignment.

The probe geometry supports rotor dynamics analysis by measuring radial shaft movement, axial position changes, and vibration response. Furthermore, the armored cable construction reduces mechanical damage risks in industrial installation environments while maintaining signal transmission integrity.

Frequently Asked Questions

Q: What type of signal does the 330104-00-10-10-02-00 generate?
A: The probe generates an eddy-current displacement signal through a compatible 3300 XL Proximitor Sensor. The system converts probe impedance changes into proportional vibration and position voltage outputs.

Q: Can this probe operate with other 3300 XL system components?
A: Yes. The 330104-00-10-10-02-00 is designed for compatibility with 3300 XL Proximitor Sensors and matching extension cable assemblies.

Q: What installation factor affects measurement accuracy?
A: Probe gap setting directly affects measurement accuracy. Technicians should verify the installation gap voltage and maintain correct probe alignment according to Bently Nevada system requirements.

Field Installation Guidelines

• Install the probe with the M10 x 1 threaded section secured according to the mechanical drawing requirements.
• Maintain proper probe tip clearance from the shaft target surface before system calibration.
• Verify the gap voltage after installation to confirm the probe operates within the expected measurement range.
• Route the armored cable away from high-current power conductors and strong electromagnetic interference sources.
• Connect the ClickLoc connector securely and inspect the cable armor for mechanical damage before commissioning.
• Confirm the target surface material matches the specified AISI 4140 steel calibration condition or apply the required system calibration procedure.
