I. Model Positioning (Detailed Analysis Section by Section)

330930: 3300 XL NSv Series Extension Cable

065: Cable Length 6.5 m (21.3 ft)

05: Stainless Steel Armor (Armor), resistant to mechanical damage and high temperature

05: CSA/ATEX/IECEx Explosion-proof Certification, suitable for hazardous areas

Usage: Combined with 330900 Series NSv probes and 330980 Series Preprocessors, used for shaft vibration, axial displacement, phase/key frequency monitoring in narrow spaces, high temperatures, and explosion-proof environments.

II. Core Parameters

1. Mechanical Characteristics

Length: 6.5 m

Structure: With stainless steel armor, inner insulation + shielding layer + armor protection layer

Connectors: Both ends standard coaxial ClickLoc connectors, quick plug-in, waterproof, 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

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

3. Environment and Certification

Operating Temperature: -40°C ~ +125°C (Armor can withstand higher temperatures)

Protection Grade: IP67

Certification: CSA, ATEX, IECEx Explosion-proof Certification

Anti-Vibration: 10 g (10–1000 Hz)

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

Probe: 330901-00-00 (Standard NSv Probe, M10×1 Thread)

Preprocessor: 330980-50-00 / 330980-70-00

Total Length Matching: Internal Length of Probe + Length of Extension Cable = Nominal Length of Preprocessor

Example: Probe 1.0 m + Cable 6.5 m = Preprocessor 7.5 m (Must be consistent during ordering)

Monitoring Rack: 3300 TSI, 3500 TSI

Monitoring Module: 3500/40M (Vibration), 3500/50M (Phase/Speed)

330930-065-05-00 6.5 m ✅ Present ❌ Absent

V. Installation Points

Length Matching: Ensure that the probe + cable = total length of the preamplifier. Otherwise, the signal will be non-linear.

Connector Protection: Prevent oil and dust from entering the connector. Cover the connector with a protective cap after installation.

Cable Fixation: Fix every 0.5–1 m to avoid vibration wear; keep away from high-temperature and high-pressure pipelines.

Grounding Specifications: Only the single end of the shielding layer is grounded on the preamplifier side to prevent circulating interference.
