The Bently Nevada 78432-02 is a dedicated accessory for eddy current sensor systems, primarily
designed to support signal transmission and compatibility between Bently Nevada proximity probes,
extension cables, and rotating machinery protection systems (e.g., 3300 Series). It functions as a
critical interface component, ensuring stable transfer of gap voltage signals—essential for accurate
measurement of shaft vibration, position, or thrust in industrial rotating equipment like turbines,
compressors, and pumps.
Engineered to match Bently Nevada’s sensor system specifications, it maintains signal integrity to
avoid distortion that could impact monitoring accuracy. The accessory is built for industrial durability,
compatible with typical on-site operating conditions, and requires pairing with genuine Bently
Nevada probes/extension cables to ensure optimal performance. During installation, it must be wired
per the product manual to align with the sensor system’s electrical parameters, supporting reliable
machinery condition monitoring and protection.
▲Function
The Bently Nevada 78432-02 is a rugged, industrial-grade extension cable assembly specifically designed for Bently Nevada’s eddy current proximity sensors (e.g., 3300 Series Proximitor sensors) and machinery health monitoring systems. Its core function is to establish a low-loss, shielded connection between field-mounted proximity sensors and upstream signal conditioners or monitoring hardware (such as 3500 Machinery Health Monitor frames), enabling the reliable transmission of high-fidelity eddy current signals that measure critical rotating equipment parameters—including shaft radial vibration, displacement, and rotor position. Constructed with EMI/RFI-shielded conductors and durable, environment-resistant connectors, it protects signal integrity from electromagnetic interference, temperature fluctuations (-40°C to 85°C), oil, dust, and mechanical vibration—common in harsh industrial settings like oil & gas refineries, power generation plants, and chemical processing facilities. Additionally, it is factory-calibrated to match Bently Nevada’s sensor specifications, ensuring consistent measurement accuracy and preventing signal degradation that could lead to false alarms or missed early warnings of machinery faults (e.g., bearing wear, shaft misalignment). This cable assembly plays a vital role in maintaining the integrity of machinery health monitoring workflows, supporting predictive maintenance and minimizing unplanned downtime for high-value rotating assets.
