Product Description
84661-25 is the original factory-provided signal cable for the Bently 330500 series Velomitor piezoelectric speed vibration sensor, used for signal transmission and power supply between the sensor and the monitoring system (such as 3500/3300 series). The cable adopts a shielded + armored structure, with strong anti-interference ability, oil and corrosion resistance, and tensile and wear resistance. It is suitable for high-temperature/high-vibration industrial sites, ensuring low-loss, high-fidelity, and stable long-distance transmission of vibration signals. It is a key connection component for unit condition monitoring and protection systems.
