Hardware Specifications

Eddy-Current Scaling and Gap Voltage

The 330104 probe operates as part of an eddy-current displacement measurement system. The probe and associated Proximitor sensor establish a calibrated relationship between shaft position and output voltage. Therefore, technicians should verify the installed probe gap and electrical output before accepting vibration or position measurements.

For a typical Bently Nevada installation, technicians can validate the electrical gap condition against the applicable Proximitor system target, commonly using a nominal -10 VDC gap reference. The actual acceptance value must follow the specific Proximitor sensor and monitoring-system documentation.

The 2.0 mm linear range corresponds to the specified displacement measurement region. Consequently, target material, probe gap, cable configuration, and mechanical runout can directly affect measurement accuracy.

Frequently Asked Questions (FAQ)

Q: What measurement range does the 330104 probe provide?
A: The specified linear measurement range is 2.0 mm / 80 mils, beginning approximately 0.38 mm / 15 mils from the probe tip.

Q: What cable configuration does 330104-00-05-10-11-CN use?
A: This configuration uses a 1.0 m / 3.3 ft FluidLoc coaxial cable with a miniature coaxial ClickLoc connector and connector protector.

Q: What target material applies to the specified sensitivity and linearity?
A: The supplied specifications use standard AISI 4140 steel as the target material. Other conductive materials can produce different measurement characteristics.

Field Installation Guidelines

• Install the M10 x 1 probe into a mechanically stable mounting location with sufficient clearance for the target surface.
• Position the probe perpendicular to the monitored shaft surface where the mechanical design permits.
• Keep the probe sensing area free from mechanical obstruction, excessive contamination, and unintended conductive structures.
• Verify the installed probe gap using the applicable Bently Nevada installation procedure before commissioning.
• Check the DC output and confirm the gap voltage corresponds to the specified Proximitor system setup.
• Route the coaxial cable separately from high-current power conductors and high-energy switching circuits where practical.
• Avoid sharp cable bends, excessive mechanical tension, and conditions that could damage the FluidLoc cable construction.
• Maintain the specified connector interface and ensure the ClickLoc connection is fully seated.
• Verify cable shielding and grounding according to the associated Proximitor sensor and monitoring-system wiring documentation.
• Confirm the target material and mechanical runout before interpreting vibration amplitude or shaft-position data.
