Eddy-Current Probe Scaling and Rotor Dynamics Measurement
The 330103-00-03-90-12-05 uses eddy-current sensing technology to convert the distance between the probe tip and the conductive shaft surface into a proportional output voltage. Therefore, the connected Proximitor sensor can process static shaft position and dynamic vibration signals within the 3300 XL monitoring architecture.
The probe supports rotor dynamics analysis by measuring radial and axial shaft movement on fluid-film bearing machines. Moreover, the probe design follows API 670 mechanical configuration requirements for probe dimensions, linear range, accuracy, and temperature stability.
The probe incorporates TipLoc molding technology to strengthen the connection between the sensing tip and probe body. In addition, the CableLoc design provides a 330 N (75 lbf) pull strength for improved cable retention during mechanical installation.
The miniature coaxial ClickLoc connector provides a corrosion-resistant connection interface, while the FluidLoc cable design reduces the risk of fluid migration through the cable assembly. Furthermore, the probe maintains backward compatibility with selected non-XL 3300 series 5 mm and 8 mm transducer system components.
Frequently Asked Questions
Q: What measurement signals does the 330103-00-03-90-12-05 provide?
A: The probe provides displacement-related electrical output through an eddy-current measurement principle. The output represents the distance between the probe tip and the observed conductive shaft surface when connected to a compatible Proximitor sensor.
Q: Can the 330103-00-03-90-12-05 measure both vibration and shaft position?
A: Yes. The probe supports both dynamic vibration measurement and static shaft position measurement in 3300 XL proximity monitoring applications.
Q: What installation connection does this probe use?
A: The probe uses an M10 x 1 threaded mounting configuration with a miniature coaxial ClickLoc connector and FluidLoc cable assembly.
Field Installation Guidelines
- Install the probe with the specified M10 x 1 mounting thread and maintain proper mechanical alignment with the monitored shaft surface.
- Verify probe gap adjustment through the compatible Proximitor sensor before commissioning the monitoring channel.
- Route the coaxial cable away from high-current power conductors and strong electromagnetic interference sources.
- Maintain proper cable bending radius and avoid mechanical stress on the ClickLoc connector area.
- Connect cable shielding according to the machinery monitoring system grounding practice to reduce electrical noise.
- Confirm the probe tip condition and mounting surface cleanliness before final calibration.
- Use compatible 3300 XL extension cables and Proximitor sensors to maintain system measurement characteristics.
