Piezo-Electric Accelerometers - A/38 - 1

Micro-miniature triaxial piezo-electric accelerometer A/38, A/38-1 0.4pC/g nom./axis icro-miniature triaxial vibration transducer comprising three shear plate. A/28/E inserts bonded orthogonally into a hard anodised aluminium housing. The inserts are electrically insulated, individually and from the housing, thus eliminating ground loop interference. The 3 output connectors of the A/38-1 are in the same horizontal plane. The spatial response of a structure to dynamic forcing may lead to erroneous single axis vibration or shock measurement, due to the inherent directional property of the transducer. FREQUENCY RESPONSE TEMPERATURE RESPONSE In cases where this is deemed to be a problem, an orthogonal three axis measurement, allowing computation of absolute value and direction offers a solution. The additional mechanical isolation implicit in the construction provides also near elimination of strain induced error.
