Hardware Specifications

Eddy-Current Signal Transmission and Cross-Talk Control

The 330854 extension cable forms part of a matched 3300 XL 25 mm transducer system consisting of a proximity probe, extension cable, and Proximitor sensor. Electrical characteristics are controlled across the complete assembly to preserve transducer calibration and displacement measurement accuracy.

The 75 Ohm triaxial construction supports stable signal transmission between sensing and conditioning components while minimizing susceptibility to external electromagnetic interference. Proper cable routing and shield continuity help reduce cross-talk effects in installations containing multiple proximity transducer systems.

FluidLoc construction provides an internal sealing mechanism designed to restrict the migration of liquids through the cable structure, helping maintain signal path integrity in lubricated machinery environments.

Frequently Asked Questions

Q: Can the 330854-040-24-05 be used with non-3300 XL transducer systems?
A: The cable is designed for use within calibrated 3300 XL 25 mm transducer systems. Mixing components from different transducer families can affect calibration accuracy and system performance.

Q: Does the extension cable influence transducer sensitivity?
A: Yes. The extension cable is part of the calibrated transducer system. The specified electrical length and impedance are required to maintain the rated system sensitivity and linearity.

Q: Is the cable suitable for high-temperature machinery locations?
A: Yes. The high-temperature FluidLoc construction is rated for continuous operation from -51 deg C to +177 deg C and can tolerate short-term exposure up to +250 deg C for limited durations.

Field Installation Guidelines

• Verify compatibility between the extension cable, probe, and Proximitor sensor before installation.

• Do not modify cable length, splice conductors, or replace factory-installed connectors.

• Route extension cables separately from high-voltage power wiring and motor leads.

• Maintain minimum mechanical stress on cable connectors during installation and operation.

• Ensure armor assemblies and cable shields remain electrically continuous throughout the transducer system.

• Avoid excessive bending, crushing, or twisting of the triaxial cable assembly.

• Inspect cable jackets and connector interfaces for damage before commissioning.

• Confirm transducer system calibration requirements are satisfied after installation.
