Model: 3500/54 (286566-01 + 133396-01)
Brand: Bently Nevada
Series: 3500 Series Machinery Protection and Condition Monitoring System
Description: The Bently Nevada 3500/54 overspeed detection system is a dual-channel tachometer module designed to provide precise monitoring of rotational speed in critical industrial machinery. It processes input signals from proximity probes, magnetic pickups, or tachometers to determine shaft rotational speed, rotor acceleration, and rotor direction. The system compares these measurements against user-programmable alarm setpoints and generates alarms when the setpoints are violated. The module can be configured to supply conditioned Keyphasor® signals to the backplane of the 3500 rack for use by other monitors.
