Page 4: General Description And Operation
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. Accelerometer monoaxial 4511-W-006 Fig. 1 Dimensions : All dimensions in millimeters Fig. - Page 5 The accelerometer is intended to measure the vibration of the rotor for HUMS purposes on three axes: X, Y and Z. It consists of a triaxial piezoelectric element and an electronic charge converter enclosed in a hermetic housing. The output provides a voltage signal proportional to the acceleration for each axis.

Page 18: Cleaning, Storage And Transportation
Section 6 Cleaning, Storage and Transportation Clean the accelerometer with a dry smooth cloth. Store the equipment in a polythene bag, then in a cardboard box. When the unit is packed as above, it must be stored in clean, dry, well-ventilated premises free from corrosive fumes. The temperature should be between –40 to +70°C and relative humidity between 20% and 85%.
