I. Model Breakdown

330930: 3300 XL NSv Series Extension Cable

045: Length 4.5 m

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

00: No explosion-proof certification, only applicable in non-hazardous areas

II. Core Parameters

1. Mechanical Structure

Length: 4.5 m

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

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

Minimum bending radius: ≥ 25 mm

Weight: Approximately 0.7 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 Grade: IP67

Explosion-proof: No certification (00), not allowed for use in flammable and explosive 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 cable, 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 Models of the Same Specification (4.5m) Comparison Table

Model Length Armor + FEP Explosion-proof Certification Applicable Scenarios

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

330930-045-00-00 4.5m ❌ ❌ Normal working conditions, cost priority

330930-045-01-05 4.5m ✅ ✅ Explosion-proof / Hazardous areas (oil/gas / chemical)

V. Installation Key Points

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

Joint Protection: Avoid oil and dust, use protective cap when not in use.

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

Grounding Specifications: Shield layer is only single-ended grounded on the preamplifier side, to prevent circulating interference.
