The FS601 low-frequency dual-axis accelerometer reliably measures low-frequency vibrations in wind turbines and provides software and hardware alarm signals when the vibration exceeds set limits. It features vibration and tilt monitoring, a watchdog, and self-test functions, with RS485 for parameter configuration and digital output.

▶ Using an internal accelerometer, the FS601 measures vibrations and tilt in both X and Y directions.
▶ It includes user-defined alarm thresholds and delays to prevent false alarms, with hardware alarm signals output through an internal relay when limits are exceeded.
▶ The watchdog monitors power supply and sensor status, while dedicated software allows configuration of measurement ranges, output settings, and alarm parameters via PC.
