3500-40M
The BENTLY 3500-40M also excels in diagnostic precision. It features high-resolution signal processing that captures even subtle variations in machinery behavior, such as harmonic patterns indicative of gear wear or imbalance. With dual alarm levels (Alert and Danger) per channel, it provides tiered warnings, allowing operators to respond appropriately—from scheduling maintenance for minor issues to triggering emergency shutdowns for critical faults. This nuanced approach to alarm management helps balance operational continuity with equipment protection.
