Bently Nevada 23733-03 | Standard Acceleration Interface Module

Overview

The 23733-03 is an Accelerometer Interface Module manufactured by Bently Nevada, designed for monitoring the vibration of gas turbines and aero-derivative generators. It is compatible with the Bently Nevada 3300 series, including the 3300/95 Filter Module/Vibration Monitor, as well as modified versions like 3300/15 and 3300/25.
Key Features

• Converts an accelerometer charge input into a voltage acceleration signal.
• Scales the voltage signal to 10 mV/g peak (1.02 mV/m/s² peak).
• Buffers the acceleration signal to support long-distance cable connections.
• Uses a 12th-order filter with corner frequencies defined by option BB.
• Converts the acceleration signal into a velocity signal (100 mV/in/s peak, 3.94 mV/mm/s peak).
• Supports both balanced and single-ended output configurations.
• Designed for GE LM 2500, LM 5000, LM 1600, and LM 6000 gas turbines.
