This product is a high-performance four-channel dynamic pressure monitoring module belonging to Bently Nevada’s 3500 series machinery protection system. It is specifically engineered to process signals from high-temperature pressure transducers, specializing in real-time monitoring of dynamic pressure in critical rotating machinery.The module integrates seamlessly into the 3500 series rack system and communicates with other modules through the chassis backplane, which eliminates the need for complex external wiring. It can detect subtle pressure fluctuations and identify potential equipment issues such as fluid flow instability and mechanical wear at an early stage. With ATEX and IECEx certifications, it meets the safety standards of hazardous areas and can operate stably in harsh industrial environments. It also supports the configuration of alarm setpoints and filtering functions via dedicated software, and its recorder outputs can transmit data to control systems, providing essential support for equipment predictive maintenance and operational safety in multiple industries.
