Variable
Capacitance Accelerometer Endevco Model 7596
The Endevco Model 7596 VALULINE™ accelerometer
family is a low cost solution to low-level, low frequency
measurements. The VALULINE has many of the same features
of the rugged 7290A MICROTRON® making it ideal for
applications where tight thermal characteristics are not
required. Applications include laboratory measurements,
ground transportation studies and measurements where the
accelerometer will be subjected to high shock levels (up
to 10,000 gs). Use the 7596 for modal studies on large
structures.
Gas damping and internal overrange stops enable the anisotropically
etched silicon microsensors to withstand high shocks and
acceleration loads. The use of gas damping, in the sensor,
results in very small-induced changes of frequency response.
The patented sensor design ensures immediate stability
making the unit ready to take accurate DC or dynamic data
within on millisecond.
The 7596 can operate from 9.5 VDC to 18V (or +/-4.75 to
+/-9.0 VDC) and provide a high level, low impedance output.
The output is high enough to drive most laboratory instruments,
tape recorders and data acquisition systems without amplification
or signal conditioning. The output can be fed into either
a differential or single-ended amplifier or standard bridge
electronics with 10 VDC excitation.
Endevco Model 136 Three-Channel System, Model 4430A or
OASIS Computer Controlled System are recommended signal
conditioners.
