Eddy-Current Measurement and Rotor Dynamics
The probe generates an eddy-current measurement field at the target surface. As the conductive shaft moves relative to the probe tip, the gap changes the electrical output of the associated Proximitor sensor. The monitoring system can therefore process static shaft position and dynamic shaft vibration from the same displacement measurement principle.
The supplied configuration uses an 8 mm probe tip and a nominal scale factor of 200 mV/mil. The specified 0 to 10 kHz response supports dynamic rotor measurements within the stated system conditions. Standard calibration uses AISI 4140 steel targets, so target material and shaft geometry should match the specified conditions during installation.
Frequently Asked Questions
Q: What target material does the 330104-00-08-50-02-00 use for calibration?
A: The supplied specification identifies standard AISI 4140 steel as the calibration target material.
Q: What power supply does the probe system require?
A: The associated Proximitor sensor operates from -17.5 VDC to -26 VDC, with maximum consumption of 12 mA.
Q: What connector does this configuration use?
A: The -02 configuration uses a miniature coaxial ClickLoc connector with standard cable.
Field Installation Guidelines
- Install the M10 x 1 threaded probe with the probe axis directed toward the conductive measurement target.
- Maintain the probe-to-target gap within the specified linear measurement range during normal rotor operation.
- Keep the target surface suitable for the specified AISI 4140 calibration condition where applicable.
- Route probe cabling separately from high-voltage power conductors and high-current switching circuits to reduce electrical interference.
- Avoid sharp bends, excessive mechanical tension, and abrasion along the coaxial cable.
- Maintain connector cleanliness and ensure the ClickLoc connection seats correctly before commissioning.
- Use appropriate cable shielding and grounding practices for the complete monitoring circuit. Avoid creating unintended ground loops.
- Verify the Proximitor sensor supply voltage and signal polarity before energizing the monitoring channel.
- During commissioning, verify the probe gap and output signal against the installed shaft position and the applicable monitoring-system limits.
