I. Model Breakdown

330930: 3300 XL NSv Series Extension Cable

065: Length 6.5 m (21.3 ft)

01: Stainless steel armor + FEP outer sheath (oil-resistant, temperature-resistant, wear-resistant)

00: No explosion-proof certification (not for hazardous areas)

II. Core Parameters

1. Mechanical and Structural

Length: 6.5 m

Structure: Inner insulation → Shielding layer → Stainless steel armor → FEP outer sheath

Joints: Both ends ClickLoc® coaxial quick connectors, waterproof and dustproof

Minimum bending radius: ≥ 25 mm

Weight: Approximately 1.0 kg

2. Electrical Characteristics

Compatible system: 3300 XL NSv eddy current sensor

Impedance: 50 Ω

Frequency response: 0–10 kHz

Transmission characteristics: Low loss, anti-interference, suitable for long-distance signal transmission

3. Environmental Conditions

Operating temperature: -40°C ~ +125°C (FEP + armor can withstand)

Protection level: IP67

Explosion-proof: No certification (00), for non-explosion-proof areas

Anti-vibration: 10 g (10–1000 Hz)

III. System Compatibility (Must be Matched as a Set)

Probe: 330901-00-00 (1.0 m internal cable, NSv standard probe)

Preamplifier: 330980-50-00 / 330980-70-00 (Total length should = probe length + cable length)

Example: 1.0 m (probe) + 6.5 m (cable) = 7.5 m (preamplifier order length)

Monitoring Rack: 3300 TSI, 3500 TSI

Monitoring Module: 3500/40M (vibration), 3500/50M (phase / speed)

IV. Key Models in the Same Series (6.5m) Table

Model Length Armor + FEP Explosion-proof Certification Applicable Scenarios

330930-065-01-00 6.5m ✅ ❌ General industrial environment

330930-065-05-05 6.5m ✅ ✅ Explosion-proof / Hazardous areas

330930-065-00-00 6.5m ❌ ❌ Ordinary, short-life scenarios

V. Installation Points

Length must match precisely: probe length + extension cable length = nominal length of the preamplifier; otherwise, non-linearity and inaccurate measurement will occur.

Joint protection: avoid oil and dust; cover with protective cap after installation.

Cable routing fixation: fix every 0.5–1m, away from high-temperature/high-pressure pipelines; avoid hard bending.

Grounding: only single-ended grounding of the shielding layer on the preamplifier side is required to prevent circulating interference.
