Airframe Cumulative Fatigue Monitoring System (ACFMS)

SEI's ACFMS is an advanced, low-cost data recording system capable of monitoring airspeed, altitude, and accelerations.  The "heart" of the system is the Cumulative Fatigue Recorder (CFR) Model A1000, shown top-left, capable of recording eight analog and eight digital signals.  The CFR's low power consumption, light weight, and small size allow for easy aircraft installation.  The ACFMS includes the Air Data Transducer (ADX) TR-359 (bottom-right), which converts the aircraft's pitot and static pressures into CFR compatible signals.
