Features:
- The 040 length option supplies 4.0 m of cable for a 3300 XL 11 mm measurement chain.
- Option 12 combines FluidLoc construction with a connector protector and no armor.
- Electrical construction uses 75-ohm triaxial conductors under FEP insulation.
The extension lead bridges the physical distance between the installed probe cable and the Proximitor Sensor input.
Its center conductor and coaxial jacket retain separately specified resistance limits across the 4.0 m run.
Correct system assembly depends on adding this cable length to the probe lead and matching the sum to the Proximitor length code.
The Bently Nevada 330730-040-12-00 3300 XL 11 mm Extension Cable may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Meaning of the Three Option Fields
- Length code: The 040 field selects a 4.0 m extension cable.
- Cable code: The 12 field selects FluidLoc cable with a connector protector.
- Armor choice: Option 12 remains unarmored, unlike option 13.
- Approval code: The final 00 states that agency approval is not required.
Electrical Link Between Probe and Proximitor
- Center conductor: The core carries the probe signal with 1.0 ±0.25 ohms resistance over 4.0 m.
- Coaxial return: The jacket-to-jacket path is specified at 0.3 ±0.1 ohms.
- Distributed capacitance: Cable capacitance is 69.9 pF per metre typical.
- Connector contact: Gold-plated brass contacts terminate the extension lead.
Mechanical Handling of the Lead
- Bend radius: Cable routing should maintain at least a 25.4 mm radius.
- Connector tightening: ClickLoc joints are assembled finger-tight and remain below 0.565 N-m.
- Cable mass: The unarmored lead contributes 45 g per metre before connector hardware is included.
- Joint protection: The supplied protector encloses the connected coaxial pair after assembly.
Matching the Five- or Nine-Metre Chain
- Length equation: Probe lead plus extension cable must equal the Proximitor Sensor total-length selection.
- Five-metre chain: A 1.0 m probe lead combined with this 4.0 m cable forms the 5 m route.
- Component role: The extension cable transfers the probe response but does not condition it.
- Electronics boundary: Voltage conversion and field-wiring output remain functions of the connected Proximitor Sensor.
