Eddy-Current Signal Transmission and Rotor Dynamics Monitoring

The 330190-085-00-05 maintains the electrical signal path between the 3300 XL 8 mm probe and the 3300 XL Proximitor Sensor. Therefore, the system converts probe gap distance into proportional output voltage for shaft position and vibration measurements.

The ETR extension cable supports applications where cable exposure exceeds the standard 177 deg C temperature specification. In addition, the cable construction allows operation with ETR probes rated up to 218 deg C and cable temperature exposure up to 260 deg C.

The 3300 XL system uses eddy-current measurement technology to monitor conductive shaft targets. Furthermore, the transducer chain supports rotor dynamics analysis, radial vibration monitoring, axial position measurement, and Keyphasor reference signals.

The system requires proper eddy-current probe scaling and gap voltage validation during commissioning. The standard operating target for probe gap voltage validation is typically -10 VDC, which confirms the probe operating range and signal conditioning accuracy.

Frequently Asked Questions

Q: Can the 330190-085-00-05 operate with standard 3300 XL Proximitor Sensors?
A: Yes. The ETR extension cable uses the standard 3300 XL signal interface and operates with compatible 3300 XL Proximitor Sensors.

Q: What temperature limitation applies to the 330190-085-00-05 cable?
A: The extension cable supports temperatures up to 260 deg C (500 deg F). The total system accuracy is limited by the ETR component specifications when ETR components are installed.

Q: Can this cable replace existing 3300 series extension cables?
A: The cable is interchangeable within compatible 3300 XL 8 mm systems and supports upgrades or replacements in existing installations when system configuration requirements are met.

Field Installation Guidelines

• Install the extension cable according to the 3300 XL Proximity Transducer System wiring requirements.
• Maintain separation between the transducer cable and high-current power conductors to reduce electrical interference.
• Connect cable shielding according to the system grounding specification to minimize signal noise.
• Avoid sharp bending, mechanical stress, and excessive pulling force during cable routing.
• Verify probe, extension cable, and Proximitor Sensor compatibility before commissioning.
• Perform gap voltage validation after installation to confirm correct probe positioning and signal operation.
