Bently Nevada 3500/50M Tachometer Module 

Product Number:Bently Nevada 3500/50M Tachometer Module

Product Overview

The 3500/50M Tachometer Module is a 2-channel module that accepts input from proximity probes or magnetic pickups to determine shaft rotative speed, rotor acceleration, or rotor direction. The module compares these measurements against user-programmable alarm setpoints and generates alarms when the setpoints are violated.The Tachometer Module is programmed using the 3500 Rack Configuration software. The following configuration options are available: l Speed Monitoring, Setpoint Alarming and Speed Band Alarming l Speed Monitoring, Setpoint Alarming and Zero Speed Notification l Speed Monitoring, Setpoint Alarming and Rotor Acceleration Alarming l Speed Monitoring, Setpoint Alarming and Reverse Rotation Notification141538 Rev. PThe 3500/50M Tachometer Module can be configured to supply conditioned Keyphasor signals to the backplane of the 3500 rack for use by other monitors. Therefore, you don't need a separate Keyphasor module in the rack

The Bently Nevada 3500/50M Tachometer Module is a crucial component within the Bently Nevada 3500 Series Machinery Protection System. Its primary function is to accurately and continuously monitor the rotational speed of machinery.

What the 3500/50M Does

The 3500/50M module is designed to:

Measure Rotational Speed: It takes input signals from proximity probes or magnetic pickups pointed at a shaft or gear, converting these into a precise indication of the machine's rotational speed (typically in Revolutions Per Minute - RPM).Provide Speed Alarms: Users can configure multiple speed setpoints to trigger alarms (Alert and Danger) within the 3500 system. These alarms can then activate relays (via a 3500/32M Relay Module) to alert operators or initiate automated actions.Support Speed-Related Measurements: Beyond just current speed, the 3500/50M can also provide data for related measurements such as:Rotor Acceleration: Rate of change of speed.Reverse Rotation: Detection of the shaft spinning in the wrong direction.Zero Speed: Confirmation that the machine has stopped.Generate Buffered Outputs: It provides buffered "raw" speed signals that can be sent to external diagnostic equipment, such as a Bently Nevada ADRE® system, for more in-depth analysis.Enhanced Capabilities ("M" version): The "M" in 3500/50M signifies an enhanced or newer version compared to its predecessors. This typically means improved signal processing, potentially wider measurement ranges, better diagnostics, and compliance with the latest industry standards like API 670 for machinery protection systems. It also features more robust internal diagnostics and can provide more detailed information to the system's data acquisition software.

Why Speed Monitoring is Important

Accurate speed monitoring is fundamental for the safe and efficient operation of rotating machinery:

Operational Control: Many machines operate within specific speed ranges for optimal performance.Protection Against Underspeed/Overspeed: While dedicated overspeed modules (like the 3500/54M) handle critical trip functions, the 3500/50M provides general speed monitoring and alarming for both low and high-speed conditions that are not catastrophic but require attention.Process Interlocks: Speed information can be used in control logic to enable or disable other process functions.Performance Monitoring: Tracking speed trends can help in understanding machine degradation or efficiency changes.

System Integration and Configuration

The 3500/50M operates seamlessly within the Bently Nevada 3500 Series rack:

Half-Height Module: It occupies a single half-height slot in the 3500 rack.Channel Capacity: Each module typically provides two speed input channels.I/O Module Options: Similar to other 3500 modules, it uses separate I/O modules for transducer connections. These can include internal or external termination options.Communication: The module communicates with the 3500 Rack Interface Module (RIM) and ultimately to external software (like System 1*) for configuration, data display, and alarm logging.

Typical Applications

The Bently Nevada 3500/50M Tachometer Module is widely applied across industries for continuous speed monitoring of various rotating machines:

Pumps: Monitoring operating speed to ensure flow rates and prevent cavitation.Fans and Blowers: Tracking fan speed for air flow control and preventing resonant conditions.Motors: Monitoring motor RPM for efficiency and load management.Compressors: Observing speed during startup, shutdown, and load changes.Gears and Shafts: Any application where precise rotational speed measurement is required for operational control or condition monitoring.Generators: Monitoring generator speed for synchronization and power quality.

The 3500/50M provides reliable and accurate speed data, enabling operators and maintenance personnel to proactively manage machine health and ensure safe, efficient operation.
