Hardware Specifications

Eddy-Current Probe Scaling and Rotor Dynamics

The 330190-045-00-00 extension cable is a component of the 3300 XL ETR transducer system, which is factory-calibrated for specific total system lengths to maintain a nominal scale factor of 7.87 V/mm (200 mV/mil). Impedance deviations resulting from cable length mismatches directly influence output signal linearity and the accuracy of rotor dynamics measurements. In multi-channel monitoring architectures, cables must be routed to maintain cross-talk suppression and prevent electromagnetic interference from distorting shaft vibration data processed by the TSI instrumentation.

Frequently Asked Questions

Q: Can the 4.5 metre cable length be field-modified?

A: No. The transducer system is calibrated as a matched assembly, including the probe, extension cable, and Proximitor sensor. Field-modifying the cable length alters the electrical impedance, which invalidates the calibration and induces measurement errors.

Q: Is this extension cable compatible with standard 3300 XL probes?

A: This cable is designed specifically for ETR (Extended Temperature Range) systems. While it may physically connect, the material properties and system calibration requirements differ from standard 3300 XL components; verify system compatibility with the corresponding ETR Proximitor sensor documentation.

Field Installation Guidelines

• Mounting: Secure the cable at regular intervals to prevent mechanical strain on the connectors. Use non-conductive cable ties to avoid creating potential ground loops.
• Grounding: Ensure the cable shield is maintained through the coupling to provide electromagnetic immunity. The shield must not contact the machine housing except at the designated grounding point.
• Connector Integrity: Verify that the connector mechanism is fully seated and locked. The mating surfaces must be clean and free of moisture or oil to prevent signal attenuation.
• Cable Routing: Route the coaxial cable through dedicated metallic conduit, maintaining physical separation from high-voltage AC or motor power cables to minimize induced noise.
