 The Endevco Model 2262CA accelerometers are rugged,
fluid damped transducers of the piezoresistive type. Endevco's
Piezite® Type P-11 semiconductor strain gauge 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 acquisition systems,
and low frequency galvanometers directly, without amplification.
The Model 2262CA has two active arms and two precision
fixed resistors of 900 Ohm each to provide for shunt calibration
in a six-wire system. It is provided with a six-conductor
shielded cable assembly.
These models feature a wide frequency range. Positive
overtravel stops (2262CA-25, -100 and -200) prevent damage
to the seismic system, giving an overrange capability
of 2,000 g. The use of viscous damped extends their useful
frequency range and reduces the effect of spurious, high
frequency vibrations.
Endevco Model 136 Three-Channel System, Model 4430A or
Model 68207 BCAS™ Computer Controller System are
recommended as signal conditioner and power supply.
Features:
• Rugged, fluid damped
• DC response
• 25 to 2,000 g full scale
• 6 wire system for shunt calibration
• Hermetically sealed
