1.1 Purpose
The accelerometer 4511-W-006 is intended to measure the vibration of the mechanical gearbox for HUMS purposes. It consists of a
piezoelectric element and an electronic charge converter enclosed in a hermetic housing. The output provides a voltage signal
proportional to the acceleration. It is powered by a constant current line drive supply on the same wire as the output signal.
