I. Model Breakdown

330930: 3300 XL NSv series extension cable

045: Length 4.5 m

00: No stainless steel armor (standard FEP outer sheath)

05: Explosion-proof certification (ATEX, IECEx, CSA), suitable for flammable and explosive hazardous areas

II. Core Parameters

1. Mechanical Structure

Length: 4.5 m

Structure: Inner insulation → Shielding → FEP outer sheath (without armor)

Connector: Both ends ClickLoc® coaxial quick connection, waterproof and dustproof

Minimum bending radius: ≥ 25 mm

Weight: Approximately 0.5 kg

2. Electrical Characteristics

Compatible system: 3300 XL NSv eddy current sensor

Impedance: 50 Ω

Frequency response: 0–10 kHz

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

3. Environment and Explosion-proof

Operating temperature: -40°C ~ +125°C

Protection level: IP67

Explosion-proof: 05 = ATEX/IECEx/CSA certification, suitable for Zone 0/1/2 hazardous 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 line, NSv standard probe)

Preamplifier: 330980-50-00 / 330980-60-00 (total length = probe length + cable length)

Example: 1.0 m + 4.5 m = 5.5 m (order length of the preamplifier)

Monitoring Rack: 3300 TSI, 3500 TSI

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

IV. Key Model Comparison of the Same Specification (4.5m)

Model Length Armor Explosion-proof Certification Applicable Scenarios

330930-045-00-05 4.5m ❌ ✅ Explosive areas, high explosion-proof requirements, no mechanical pulling

330930-045-01-00 4.5m ✅ ❌ General industry, wear-resistant / mechanical pulling scenarios

330930-045-01-05 4.5m ✅ ✅ Explosive areas + wear-resistant (oil/gas / chemical preferred)

V. Installation Tips

Length Matching: Probe length + extension cable length = nominal length of the preamplifier, otherwise measurement will be non-linear and inaccurate.

Connector Protection: Avoid oil and dust, use protective cap when idle.

Cable Routing Fixation: Fix every 0.5–1m, away from high-temperature/high-pressure pipes, avoid hard bending.

Grounding Specification: Shield layer is only grounded on the preamplifier side, for anti-loop interference.
