The Bently Nevada 3500/50 Tachometer Module is a critical component of the 3500 Series Machinery Protection System. It is engineered to measure rotational speed and provide phase reference signals for shafts in turbines, compressors, and other essential rotating equipment. The 3500/50-04-01 configuration provides high-integrity speed monitoring, ensuring reliable overspeed protection and accurate phase reference data for machinery diagnostics and control systems.
This module is widely used in industrial environments for monitoring speed on critical assets, including steam and gas turbines, centrifugal compressors, fans, and large motors. It serves as a primary input for safety-instrumented systems requiring overspeed detection and phase-locked vibration monitoring.
