Hardware Specifications

Mechanical Monitoring and Transducer Dynamics

The 330104 probe forms the sensing element of the 3300 XL system, providing a voltage output proportional to the gap between the probe tip and a conductive surface. This transducer is engineered to maintain signal linearity required for fluid-film bearing monitoring. Consistent eddy-current probe scaling is maintained across the system, allowing for full interchangeability of probes and extension cables without necessitating individual bench calibration. The module supports accurate gap voltage validation, where output signals are typically set to -10 VDC targets to ensure the transducer remains within its linear range for both static position and dynamic vibration measurement. The design inherently supports cross-talk suppression when multiple probes are installed in close proximity, provided standard installation spacing requirements are met.

Frequently Asked Questions

Q: Is the 330104 probe compatible with non-XL 3300 series Proximitor sensors?

A: Yes. The 3300 XL system components are backward compatible and interchangeable with 3300 series 5 mm and 8 mm components, allowing for mixed-system integration where required.

Q: Does the inclusion of hazardous area approvals (ATEX/IECEx) affect signal characteristics?

A: No. The agency approvals certify the physical design for operation in explosive environments (Ex i) but do not alter the electrical output or the characteristic impedance of the 50-ohm coaxial system.

Field Installation Guidelines

• Proximity Mounting: Secure the probe using appropriate mounting brackets. Ensure the probe tip is not in contact with the target during operation. Maintain a clear radial and axial view of the shaft surface.
• Torque Application: Tighten lock nuts to the specified torque value provided in the 3300 XL manual. Excessive torque may cause casing deformation and internal damage to the coil assembly.
• Cable Integrity: Use the ClickLoc connector system for secure engagement. Ensure the extension cable is supported to prevent mechanical stress on the connector, which could lead to intermittent contact or signal noise.
• Grounding: Verify that the shield is terminated correctly at the monitoring instrumentation end. Utilize approved safety barriers (Ex i) when installing in hazardous areas to maintain intrinsic safety integrity.
