Product Description

BENTLY NEVADA 3500 SERIES

3500/64M Dynamic Pressure Monitor

The Bently Nevada 3500/64M is a single-slot, four-channel Dynamic Pressure Monitor. It accepts signals from high-temperature pressure transducers and produces bandpass dynamic-pressure measurements for machinery protection and operating information.

Configured Spare
176449-05

3500/64M Dynamic Pressure Monitor spare part identified in the Bently Nevada 3500/64M Datasheet.

3500/64M Dynamic Pressure Monitoring

The 3500/64M continuously compares configured dynamic-pressure values with Alert and Danger setpoints to drive alarms. Each active channel has one primary measured variable: dynamic pressure direct. The monitor also provides recorder outputs for control-system applications.

What the module does

Inputs from one to four pressure transducers are conditioned into bandpass dynamic-pressure measurements. The 3500 Rack Configuration Software allows the filtering and alarm parameters to be configured for the installed application.

Gas Turbine Dynamic Pressure Application

Typical Application

Bently Nevada identifies the 3500/64M for gas-turbine dynamic-pressure, or combustion, transducers. A typical application is identifying and tracking gas-turbine combustor instabilities.

Why This Spare Is Searched

Customers may search for the 176449-05 when the installed dynamic-pressure monitoring channel is unavailable, the monitor reports an abnormal status, or the configured pressure measurement and associated alarm function need to be restored.

Protection consideration: loss of the applicable monitoring path can reduce availability of the configured dynamic-pressure information and alarm function. The actual shutdown consequence depends on the installed protection architecture and alarm logic.

Filter Configuration & Cascade Mode

Bandpass & Notch Filtering

The 3500 Rack Configuration Software configures the bandpass corner frequencies and the additional line-rejection filter. Channels 1–2 form one pair and channels 3–4 form the other; channels within a pair share the selected filtering mode.

Cascade Mode

Cascade Mode feeds the Channel 1 input to all four channels. One transducer can therefore provide input to four channels with separate bandpass filter options and full-scale ranges.

Front-Panel Diagnostics

OK

Indicates that the 3500/64M is operating properly.

TX/RX

Indicates communication between the monitor and other modules in the 3500 rack.

Bypass

Indicates that the 3500/64M is in Bypass Mode.

I/O & Replacement Check

The official ordering information identifies I/O options with internal or external termination. External termination configurations use dedicated Dynamic Pressure or Recorder Output ET Blocks. The complete installed configuration should therefore be checked before ordering a replacement.

FAQ

What is Bently Nevada 3500/64M 176449-05 used for?
It is a four-channel Dynamic Pressure Monitor used with the Bently Nevada 3500 Machinery Protection System. Bently Nevada identifies gas-turbine dynamic-pressure monitoring, including combustor-instability tracking, as a typical application.
How many channels does the 3500/64M provide?
The 3500/64M is a four-channel monitor and accepts from one to four pressure-transducer signals.
Does 176449-05 provide a recorder output?
Yes. The monitor provides an individual +4 to +20 mA recorder value for each channel.
Can the 3500/64M use Cascade Mode?
Yes. Cascade Mode feeds the Channel 1 input to all four channels, allowing one transducer input to be processed with separate bandpass filter options and full-scale ranges.
What information should I send when requesting a 176449-05 quotation?
Please send the complete Part Number, Quantity, Destination, Required Date and Machine/System Model. If the existing rack has a specific I/O termination arrangement, including that information can help with the replacement check.
