255A, 7280A, 7280AM4 and 7284 accelerometers are all near-field accelerometers characterized by different packaging.
The miniature, tubular-shaped, piezoelectric 7255A has an integral stud for mounting. The flat, low profile piezoresistive 7280A has two holes for screw mount
. The 7280A accelerometer is the unit of choice for explosive tests as these sensors have a range of 20K to 60K gâ€™s and the highest frequency response.
When vehicles are crashed for passenger safety testing, the use of the 7264H is advised as this accelerometer is dam
