The cable is lightweight and suitable for conventional pipeline wiring

2. Electrical Characteristics

Compatible system: 3300 XL NSv eddy current sensing system

Nominal impedance: 50Ω

Frequency response: 0~10kHz

Low signal loss, resistant to common electromagnetic interference, stable and reliable transmission

3. Environmental Tolerance

Operating temperature: -40℃~+125℃

Protection level: IP67

Anti-vibration level: 10g (10~1000Hz)

Suitable for general non-explosion-proof industrial scenarios

4. System Adaptation

Adapted probes: 330980 series high-temperature phase probe, NSv regular detection probe

Adapted preamplifiers: 330980-50-00, 330980-70-00

Adapted systems: 3300 TSI, 3500 TSI monitoring rack

Adapted modules: 3500/40M vibration module, 3500/50E rotational phase module

III. Installation Tips

1. The total length of the complete cable must be consistent with the calibration length of the preamplifier

2. Keep the connector clean and dry, install a protective cap when not in use

3. Fix the line in sections, keep away from high-temperature and high-pressure equipment, and avoid violent bending and pulling

4. The shielding layer is only grounded on one side of the preamplifier to avoid circulating interference with the signal

IV. Comparison of the Same Specification Models

330930-040-00-00: No armor, no explosion-proof, basic general working conditions

330930-040-01-00: With armor protection, wear-resistant and durable, non-explosion-proof environment

330930-040-01-05: Armor combined with explosion-proof certification, suitable for dangerous operation areas

V. Common Faults

Signal interruption: Check the tightness of the connector insertion and the damage of the cable outer skin

Abnormal value fluctuation: Verify the grounding method, keep the line away from strong electrical equipment

Measurement deviation exceeds standard: Check the matching degree of the total length of the complete cable
