Specification Details Part Number 3500/25 Manufacturer Bently Nevada Series 3500 Product Type Keyphasor Module Availability In Stock Country of Manufacture United States (USA) What is the 3500/25 Keyphasor Module? The 3500/25 Keyphasor Module by Bently Nevada is a crucial component in machinery monitoring systems. Designed as an enhanced version of the previous Keyphasor module, the 3500/25 plays a pivotal role in detecting shaft rotation and vibration characteristics in machinery. This half-height, two-channel module effectively translates mechanical signals into digital outputs that are essential for machinery protection and diagnostics. In essence, the 3500/25 captures Keyphasor signals, a type of pulse that occurs once per revolution (or multiple pulses per revolution) of rotating machinery. It does this using magnetic pickups or proximity probes. These signals are then converted into digital signals, enabling advanced monitoring and analysis of the machinery's rotational speed, vibration amplitude, and phase. Key Features and Functionality of the 3500/25 The 3500/25 Keyphasor Module offers several key features that make it essential for effective machinery protection: Versatile Signal Processing The 3500 Machinery Protection System can accept up to four Keyphasor signals in a standard configuration. In paired configurations, it can handle up to eight Keyphasor signals. This flexibility allows users to monitor various machinery components simultaneously, improving the overall reliability of the system. Accurate Measurement of Shaft Speed and Vibration Characteristics The primary function of the 3500/25 is to detect the precise timing of a shaft or gear's rotation using Keyphasor signals. These signals are invaluable for measuring shaft rotational speed, as well as the vibration amplitude and phase of the machinery. This capability ensures that any changes in the machinery's operating conditions are identified promptly, enabling maintenance teams to address potential issues before they lead to failures. Integration with Diagnostic Tools When combined with other 3500 monitor modules and external diagnostic tools, the 3500/25 Keyphasor Module enhances the system's ability to detect anomalies in the machinery’s operation. By monitoring changes in vibration, phase, and speed, the module provides a comprehensive view of the machinery's health, facilitating predictive maintenance and reducing downtime. The Evolution of the Enhanced Keyphasor Module The Enhanced Keyphasor Module, represented by the 3500/25, offers several improvements over its predecessor. Notably, it provides increased signal processing capabilities, making it a more powerful tool for machinery protection. Despite these upgrades, the module retains full downward compatibility with existing systems, ensuring that it can be easily integrated into legacy setups. This backward compatibility is crucial for industries that rely on older machinery systems but want to take advantage of the ...
