About brand

The BENTLY 3500 system is a professional machinery protection and condition monitoring solution widely used in industries like oil and gas, power generation, and petrochemicals. It adopts a modular design, allowing flexible configuration of monitoring modules (e.g., vibration, temperature, and speed modules) to track key operating parameters of rotating equipment such as turbines and compressors. By collecting and analyzing data in real time, it can promptly identify issues like equipment imbalance or bearing wear, trigger alarms or shutdowns when thresholds are exceeded, and effectively prevent unexpected equipment failures to ensure production continuity.
