Product Performance

The cable assembly adopts a two-core independent shielding structure combined with a braided shield with over 90% coverage, providing common mode rejection ratio ≥120dB, which can effectively resist high-frequency electromagnetic interference generated by equipment such as frequency converters and motors in industrial sites, ensuring vibration signal transmission error ≤0.1%. The 0-10kHz wide frequency response characteristic can completely retain high-frequency vibration impact signals (up to 10kHz) collected by eddy current probes, adapting to the early fault diagnosis needs of rotating machinery.

The -55°C to 125°C wide operating temperature range, combined with oil-resistant PUR sheath, enables long-term stable operation in harsh environments such as petrochemical and metallurgy, with cable service life ≥10 years. The IP67 waterproof connector adopts a threaded locking design, with plug-in life ≥500 times, and signal attenuation at the connection ≤0.05dB, ensuring long-term connection reliability.

Fully compatible with 3300 XL series probes and proximitors, signal transmission delay ≤1μs, which can be directly integrated into Bently Nevada 3500 monitoring system without additional adaptation components, with mean time between failures (MTBF) ≥500,000 hours.
