Bently Nevada 3500/44-01-00 3500/44M Aeroderivative GT Vibration Monitor

Description

The 3500/44-01-00 is a four-channel machinery protection instrument designed specifically for aeroderivative gas turbine applications. This module provides continuous machinery monitoring by comparing processed vibration parameters against user-configured alert and danger setpoints to drive dedicated alarms. The 3500/44M system interfaces with Velomitor sensors and accelerometers through specialized interface modules, supporting critical operations and maintenance data communications within a standard 3500 rack framework.

Features

• Four-channel continuous vibration monitoring optimized for aeroderivative gas turbines.
• Support for three configurable filter options: Signal Integration, 1X vibration tracking, and Band-pass vibration.
• Dual Keyphasor inputs allowing independent tracking filters for each channel pair.
• Multimode channel configuration supporting up to eight distinct sets of alarm parameters for varied machine modes.
• Front panel diagnostic LEDs for OK, TX/RX, and Bypass status indication.
• Short-circuit protected coaxial buffered transducer outputs for each channel on the front panel.

Applications

• Aeroderivative gas turbine vibration protection.
• Machinery conditional monitoring and predictive maintenance data logging.
• High-accuracy industrial tracking filter applications.

Installation Guidelines

• Rack Mounting: The main monitor module must be installed in a single full-height front slot of the 3500 rack. The paired Aero GT I/O module with internal terminations must be secured directly behind it in the corresponding full-height rear slot.
• Wiring and Terminations: Direct wiring connections should be made to the designated terminals on the internal termination block of the rear I/O module. Ensure all sensor shields are properly grounded at the chassis ground lugs provided on the rack frame.
• Filter Configuration: System configuration must be programmed via the 3500 Rack Configuration Software to assign the proper integration, tracking, or band-pass filters based on sensor type and machine specifications.
