3500/44M Aeroderivitive GT Vibration Monitor

Product DatasheetBently Nevada* Asset Condition Monitoring

DescriptionThe 3500/44MAeroderivitive GT Vibration Monitor is a four-channel instrument designed for aeroderivative gas turbineapplications. The Aero GT I/O modules interface to velocitytransducers through Bently Nevada* interfacemodules, partnumbers 86517and 86497. Themonitor uses the Prox/Velom I/Oto interface to our Velomitor* sensors and accelerometers.

Using the 3500Rack Configuration Software, you can configurethe 3500/44MAeroderivitive GT Vibration Monitor for thefollowing filter options:

n Signal Integrationn 1X vibration trackingn Band-pass vibration

The 3500/44MAeroderivitive GT Vibration Monitor accepts inputfrom two separate Keyphasor* signals, allowing each channelpair to use a different tracking filter.

The 3500/44MAeroderivitive GT Vibration Monitormeets therecommended requirements of the following aeroderivative gasturbinemanufacturers:

n Rolls Royce: RB211, Avonn General Electric: LM1600, LM2500, LM5000, LM6000n United Technologies: Turbo Power GG 3, G44, FT 4, FT 8

The primary purpose of the 3500/44MAeroderivitive GT VibrationMonitor is to provide the following:

n Machinery protection by continuously comparing monitoredparameters against configured alarm setpoints to drive alarms

n Essential machine information for both operations and maintenancepersonnel

You can configuremultimode channels to have up to eight setsof alarmparameters including alert and danger setpoints and

alarm time delays. Each setmay be configured fora specific machinemode.

As themachine changesmodes, themonitor canswitch to a specific set using contacts onmultimode I/O modules or software commandsthrough a communications gateway.

Alarms

Alarm setpoints

You can set Alert levels for various valuesmeasured by the monitor and Dangersetpoints for up to two of the valuesmeasured by the monitor usingconfiguration software.

Alarms are adjustable from 0 to 100% offull-scale for each measured valueexcept when the full-scale rangeexceeds the range of the transducer. Inthis case, the range of the transducer willlimit the setpoint.
