Hardware Specifications

Gap Voltage Stability and Cross-Talk Suppression

The 330130 extension cable is a calibrated component within the 3300 XL transducer system. Electrical length, cable impedance, and connector characteristics are controlled to maintain system accuracy and repeatability.

Proper matching between the proximity probe, extension cable, and Proximitor sensor is required to achieve the intended system linearity and gap voltage characteristics. During commissioning, gap voltage verification is commonly performed to confirm that the transducer system operates within its calibrated measurement region, typically centered near the standard -10 VDC operating target.

The triaxial cable construction and continuous shielding arrangement assist in suppressing electromagnetic interference and reducing cross-talk between adjacent monitoring channels installed on the same machine train.

Frequently Asked Questions

Q: Can the extension cable be shortened or field-spliced?
A: No. The cable is part of a calibrated transducer system. Modifying the cable length or connector assembly can alter system characteristics and affect measurement accuracy.

Q: Does the cable require a specific total system length?
A: Yes. The extension cable must be matched with the appropriate 3300 XL probe and Proximitor sensor configuration to achieve the specified 5 m or 9 m system length.

Q: What is the function of the connector protector?
A: The connector protector helps reduce contamination from moisture, lubricants, and industrial contaminants while providing additional mechanical protection at the connection interface.

Field Installation Guidelines

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

• Do not alter cable length or replace factory-installed connectors.

• Route signal cables separately from motor feeders, VFD output cables, and high-current conductors.

• Maintain shield continuity throughout the complete transducer system.

• Prevent excessive bending, crushing, twisting, or tensile loading of the cable assembly.

• Ensure CableLoc connectors are fully engaged and mechanically secured.

• Inspect armor, connectors, and protective fittings for physical damage before commissioning.

• Confirm acceptable gap voltage values after installation and prior to machine startup.
