The BENTLY NEVADA 135489-02 is a high-performance I/O module designed for industrial machinery monitoring systems, specifically engineered to integrate seamlessly with the Bently Nevada 3500 Series platform. As a critical component of predictive maintenance solutions, this module provides advanced signal conditioning and data acquisition for rotating machinery, ensuring reliable health monitoring of turbines, compressors, generators, and other critical assets.
Engineered with precision, the 135489-02 features four independent channels: two Proximity/Acceleration (Prox/Accel) channels and two Velomitor channels. This configuration allows simultaneous monitoring of radial vibration, axial position, and velocity measurements, enabling comprehensive analysis of machinery dynamics. The module’s internal barriers and terminations eliminate the need for external signal isolation components, simplifying installation and reducing cabling complexity. By delivering real-time data on vibration amplitudes, phase angles, and temperature, the 135489-02 empowers engineers to detect early signs of mechanical degradation, minimizing unplanned downtime and extending equipment lifespan.
Built to withstand harsh industrial environments, the 135489-02 operates reliably in temperatures ranging from -20°C to +60°C and features an IP65-rated enclosure for protection against dust and water ingress. Its modular design ensures compatibility with the 3500 Series rack system, supporting hot-swappable replacement for seamless maintenance. With support for multiple communication protocols (e.g., RS485, Modbus RTU), the module facilitates integration with SCADA systems, DCS platforms, and cloud-based analytics tools, providing a unified view of machinery health across distributed networks.
