🔧 BENTLY NEVADA 3300 Vibration / Velocity / Acceleration Sensor Module
The Bently Nevada 3300 Series vibration, velocity, and acceleration measurement module is a robust industrial monitoring component designed for high-precision machinery protection. Its architecture provides stable, low-noise signal conditioning, consistent dynamic response, and dependable performance in high-temperature or high-vibration environments. Built for critical rotating assets such as turbines, compressors, gearboxes, and motors, the 3300 module integrates seamlessly with traditional Bently Nevada racks and ensures accurate real-time diagnostics.
📌 Product Overview
The 3300 module processes vibration displacement, velocity, and acceleration signals using advanced analog filtering and high-integrity circuitry. It accepts input from standard eddy-current proximity probes, seismic velocity transducers, or piezoelectric accelerometers. Once installed, the module delivers trustworthy proportional outputs for both monitoring and control layers of a plant’s protection system.
Designed with ruggedness and minimal drift characteristics, the 3300 maintains measurement stability over long operating cycles. Its internal circuitry optimizes dynamic range, reduces interference, and supports precise threshold configuration. The result is predictable, repeatable machine condition assessment suitable for safety-critical environments.
