Bently Nevada 3500/50-04-00 136703-01 Technical Specifications, Product Introduction, Applications, Advantages, Brand, Series, and Recommended Models
Product Introduction
The Bently Nevada 3500/50-04-00 136703-01 is a high-performance Tachometer Module designed for the 3500 Machinery Protection System. It is a dedicated monitoring module used for accurate rotational speed measurement, overspeed detection, and speed-related protection functions for critical rotating machinery.
The primary purpose of the 3500/50-04-00 136703-01 is to continuously monitor machine speed and provide reliable speed information for operational monitoring, alarm functions, and protection systems.
Rotating equipment such as turbines, compressors, generators, and high-speed mechanical systems require precise speed control to maintain safe operation. Abnormal speed conditions, especially overspeed events, may cause severe mechanical stress, rotor damage, or catastrophic equipment failure.
This tachometer module receives input signals from compatible speed sensors and processes these signals to calculate accurate rotational speed values. The processed speed information can then be used by the protection system to evaluate machine operating conditions and initiate appropriate alarms or protective actions.
The 3500/50-04-00 136703-01 is designed for applications where fast response, reliable speed measurement, and continuous online monitoring are required.
The module operates as part of a modular rack-based machinery protection platform. It communicates with other modules through the internal rack backplane, allowing integration with vibration monitoring modules, position monitoring modules, relay modules, and communication interfaces.
The module supports real-time monitoring during different machine operating stages, including startup acceleration, normal running, load variation, and shutdown deceleration.
The plug-in modular construction allows easy installation, replacement, and maintenance. Engineers can replace the module without major modifications to the existing protection cabinet.
The 3500/50-04-00 136703-01 provides stable speed monitoring performance, reliable protection capability, flexible configuration, and long-term industrial durability, making it suitable for demanding rotating equipment applications.
