General Description
Kistler shock accelerometers are shear mode shock and vibration
measuring instruments. These units are intended for pyroshock
testing, metal-to-metal impact studies, drop testing, etc. A self-
generating piezoelectric sensing element is used in conjunction with
the built-in, internal circuit Piezotron* impedance converter. As with
most accelerometers, the sensitivity of this series is expressed in terms
of the ratio of the electrical output to applied acceleration (e.g.
mV/g). In the case of Piezotron devices such as used in this
accelerometer, the output is a low impedance voltage signal which is
proportional to the applied acceleration.
Being a low impedance device, no charge amplifier or special cabling is
required and transmission over long lines is possible with a minimum
of noise pick-up.
