Description
BENTLY 3500/22M Transient Data Interface (TDI)
1. Product Description
The BENTLY 3500/22M is a high-performance transient data interface module designed for advanced condition monitoring of rotating machinery. As part of the BENTLY 3500 series, this module bridges the gap between the 3500 monitoring system and software platforms like System 1, enabling real-time analysis of steady-state and transient data. Unlike its predecessor (3500/22), the 3500/22M captures high-frequency vibrations during critical events such as startups, shutdowns, and fault conditions, making it ideal for predictive maintenance and fault diagnosis. Its Ethernet connectivity and modular design ensure seamless integration with BENTLY’s vibration sensors and other system components.
