Lifetime Monitoring System for Actuators

The onboard SKF actuator lifetime monitoring system continuously tracks actuator service-life status while in operation and signals when the actuator needs to be replaced.

The system displays remaining service life via a simple LED color code display, using specific calculations. Green indicates more than 10% service life and orange indicates that only 10% remains. When an actuator reaches the end of its service life, the LED turns red and a buzzer sounds.

It also includes a memory device mounted in each actuator to record usage in real time and a download interface to collect usage data for accurate record-keeping and maintenance planning. A more sophisticated version can connect to a PC/laptop or a pocket PC (PDA) to capture a variety of data for further analysis.
