Bently Nevada 86517-01-01-01-02 Acceleration/Dynamic Pressure Interface Module

The Bently Nevada 86517-01-01-01-02 is a high-precision charge amplifier interface module designed for the Bently Nevada 3500 machinery protection system, serving as a core supporting component for industrial mechanical condition monitoring. It is mainly compatible with piezoelectric accelerometers and dynamic pressure sensors, converting weak sensor charge signals into standard voltage signals to realize accurate acquisition and transmission of rotating machinery vibration, impact and dynamic pressure data, providing reliable data support for unit fault early warning, condition analysis and protection interlock.

Equipped with fixed filter bandwidth and standard bias voltage output, the module features electrical isolation, loop self-inspection and fault diagnosis with excellent industrial adaptability. It is widely used in online monitoring systems for major rotating equipment such as thermal power units, gas turbines, fans and compressors, acting as an essential front-end signal conditioning unit in the Bently Nevada 3500 machinery protection system.
