Description

Function Features

Dual Sensor Compatibility: It can process both proximity sensor signals related to vibration and position and seismic sensor signals such as acceleration and velocity. This dual compatibility eliminates the need for multiple single-function modules, reducing system complexity and cutting installation costs significantly.
Comprehensive Measurement Capabilities: Each channel can be programmed via 3500 framework configuration software. It can measure multiple key parameters including radial vibration, thrust position, eccentricity, differential expansion, velocity and acceleration, covering all core health indicators of rotating machinery.
Reliable Alarm Mechanism: Users can program alarm thresholds based on specific equipment operating conditions. The module continuously compares real-time measurement data with preset thresholds and triggers alarms promptly when abnormalities occur, providing a solid guarantee for timely equipment protection.
Stable Signal Processing: It is equipped with built-in signal conditioning functions such as filtering and amplification. These functions effectively reduce electrical interference and noise in industrial environments, improving the accuracy and stability of signal transmission and ensuring the reliability of measurement results.
Convenient Maintenance and Installation: Its modular design fits perfectly with 3500 series racks, simplifying installation procedures. The hot-swappable feature allows maintenance personnel to replace the module without interrupting the entire monitoring system, minimizing production losses caused by maintenance.
Strong System Compatibility: It integrates seamlessly with the Bently 3500 monitoring framework via the backplane. It can smoothly interact with the overall system for data, supporting the unified management and analysis of equipment monitoring data in large-scale industrial scenarios.
