Products Description
Bently Nevada 3500/44M Gas Turbine Vibration Monitor in stock
Bently Nevada 3500/44M is a dedicated 4-channel vibration monitor for aeroderivative gas turbines within the 3500 machinery protection system. It accepts signals from accelerometers and velomitor sensors, supporting 1X tracking filter and band-pass vibration measurement for gas turbine protection.

This module supports dual Keyphasor inputs, each channel pair can use independent tracking filters. It provides 4-20mA recorder output and two-level alarm configuration, widely used for gas turbine condition monitoring and trip interlock protection.
