Hardware Specifications

Gap Voltage Validation and Signal Integrity

The 330730 extension cable is a calibrated component of the 3300 XL 11 mm proximity transducer system. Proper operation requires installation with a compatible proximity probe and Proximitor sensor configured for the specified system length.

Maintaining the correct electrical length is necessary to preserve transducer calibration, linearity, and gap voltage characteristics. During commissioning, gap voltage verification is commonly performed to confirm that the probe and target operate within the calibrated measurement region, typically centered near the standard -10 VDC target used in Bently Nevada proximity measurement systems.

The cable assembly supports signal transmission while minimizing measurement deviation caused by impedance mismatch or improper system-length configuration.

Frequently Asked Questions

Q: Can the 330730-080-00-00 extension cable be used independently as a sensor?
A: No. The extension cable is only one component of the complete transducer system and must be used with a compatible 3300 XL probe and Proximitor sensor.

Q: Does cable length affect measurement performance?
A: Yes. The extension cable forms part of the calibrated electrical length of the transducer system. Correct cable length selection is required to maintain specified system performance.

Q: Is the cable suitable for high-humidity environments?
A: Yes. The assembly is specified for operation in environments with up to 100% relative humidity under non-submerged conditions and incorporates a hermetically sealed construction.

Field Installation Guidelines

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

• Do not shorten, splice, or modify the extension cable assembly.

• Route signal cables separately from power distribution and motor cables.

• Protect cable runs from crushing, abrasion, and excessive bending forces.

• Confirm connector engagement is fully secured before system startup.

• Maintain shield continuity throughout the complete transducer system.

• Verify acceptable gap voltage values during commissioning.

• Inspect cable jackets and connectors periodically for mechanical damage.
