The Endevco® model 2262A accelerometers are rugged, fluid
damped transducers of the piezoresistive type. Endevco’s
Piezite® type P-11 semiconductor strain gage elements are
used in a bridge configuration, providing a low impedance
output with 10 Vdc excitation. The output is high enough to
drive most tape recorders, data aquisition systems, and low
frequency galvanometers directly, without amplification.
Viscous damping extends their useful frequency range and
reduces the effect of spurious, high frequency vibrations.
Typical applications for these accelerometers include
transportation environmental testing and transient
accelerations on structural members.
Endevco model 126, 136 or 436 recommended as signal conditioner and power supply.
