Product Overview
The Bently Nevada 3500/25 Enhanced Keyphasor Module is an advanced, half-height, two-channel module used within the 3500 Machinery Protection System. Its primary function is to provide a precise timing signal, known as the Keyphasor signal, to other monitor modules in the 3500 rack.
This module accepts input signals from proximity probes or magnetic pickups. It then converts these signals into a digital Keyphasor signal, which marks when a Keyphasor mark on a rotating shaft aligns with the transducer. This once-per-turn or multiple-event-per-turn pulse is critical for:
-
Measuring shaft rotative speed.
-
Determining vector parameters like 1X vibration amplitude and phase.
The original 125792-01 PWA (Printed Wiring Assembly) has been replaced by the 149369-01 module, which enhances signal processing capabilities while maintaining full backward compatibility in terms of form, fit, and function. The enhanced version includes:
-
Generation of once-per-turn event signals from multi-event-per-turn inputs.
-
Field-upgradeable firmware for future updates.
-
Asset management data reporting to track system health.
Designed for industrial applications, the 3500/25 module is configured for various I/O options, including isolated and non-isolated versions. It also features two buffered Keyphasor outputs located at both the front and back of the rack, enabling easy integration with external diagnostic equipment.
