Description
BENTLY NEVADA 3500/25 149369-01 Enhanced Keyphasor Module
The
BENTLY NEVADA 3500/25 149369-01 is a half-height, dual-channel module designed for the 3500 Machinery Monitoring System. It converts analog signals from proximity probes or magnetic pickups into digital keyphasor signals, indicating when a shaft’s keyphasor mark aligns with the transducer. This module is critical for precise rotational speed measurements, vibration analysis, and machinery protection in industries such as oil & gas, power generation, and manufacturing. Its enhanced features, including field-upgradeable firmware and advanced signal processing, ensure compatibility with modern and legacy systems.
