Model Explanation (330730-AAA-BB-CC)

330730: 11mm XL series extension cable

040: Cable length 4.0m

03: With armor (Armored), enhanced resistance to mechanical damage

00: Without explosion protection, standard industrial model

Core Parameters

Compatible probe: 330703 series (11mm, such as 330703-000-040-...)

Compatible preamplifier: 330780 series (11mm, such as 330780-50-00)

Total system length: Probe cable + Extension cable = 5m or 9m (must match the preamplifier)

Armor: Stainless steel braided layer, resistant to pressure, bending, and rat bites

Outer diameter: Approximately 6mm

Temperature: -40℃ ～ +125℃

Protection: IP67

Joints: Standard M12 threaded joints at both ends (probe end / preamplifier end)

Differences from common models (11mm extension cable)

330730-040-00-00: 4m, without armor, ordinary

330730-040-03-00: 4m, armored (your current model)

330730-040-03-05: 4m, armored, explosion-proof (ATEX/IECEx)

Typical complete set configuration (5m system, armored, non-explosion-proof)

Probe: 330703-000-010-50-02-00 (1m probe cable)

Extension cable: 330730-040-03-00 (4m armored)

Preamplifier: 330780-50-00 (5m, panel, non-explosion-proof)

Installation Tips

Do not cut the length at will, must maintain the original total length

Both ends of the armor layer are grounded, single-ended grounding of the shielding layer (preamplifier side)

Bending radius ≥ 50mm, avoid hard folding

Used for steam turbine, compressor, fan shaft vibration / displacement monitoring in non-explosion-proof areas
