Eddy-Current Probe Scaling and Gap Voltage
The 330104 probe forms the sensing portion of an eddy-current proximity transducer system. The probe generates an electromagnetic field at its tip, and the system converts changes in the gap between the probe tip and a conductive machine target into an electrical measurement.
During commissioning, technicians should verify the probe gap and associated transducer output against the applicable 3300 XL system requirements. A negative DC gap-voltage target, commonly referenced around -10 VDC in Bently Nevada proximity probe installation practice, provides a useful validation point when the associated Proximitor and system documentation specifies it.
The probe itself does not provide an independent powered measurement output. Instead, the connected Proximitor sensor interface supplies the excitation and processes the probe signal.
Frequently Asked Questions
Q: What cable configuration does 330104-00-08-50-12-00 use?
A: This configuration uses a miniature coaxial ClickLoc connector and FluidLoc cable, with a total cable length of 5.0 m.
Q: What does the 08 suffix specify?
A: The 08 option specifies an overall case length of 80 mm.
Q: Does the 00 agency approval suffix indicate a specific certification?
A: No. The 00 option indicates that agency approval is not required for this configuration.
Field Installation Guidelines
Install the probe so that its sensing axis faces the intended conductive target and maintain the specified mechanical gap required by the associated 3300 XL system documentation.
Route the coaxial cable separately from high-current power conductors, switching circuits, and other strong electromagnetic noise sources. Avoid sharp bends, excessive mechanical stress, and repeated flexing near the connector.
Use the specified ClickLoc connection method and ensure that the connector is fully engaged before commissioning. Do not apply mechanical load to the connector during cable routing.
For shield and grounding practices, follow the grounding arrangement specified for the complete 3300 XL proximity transducer system. Avoid creating unintended ground paths through the probe cable shield.
After installation, verify the probe gap, connector engagement, cable condition, and system output before placing the machinery monitoring channel into service.
