Model 7292-XM1 Variable Capacitance Accelerometer
measures Low-Level accelerations.
Endevco's new Model 7292-XM1 utilizes unique
variable-capacitance microsensors for the measurement
of low-level accelerations in rugged aerospace and
Because it can respond to DC accelerations (steady-state events),
the accelerometer is ideal for measuring whole-body motion immediately
after being subjected to shock motion and in the presence of severe
vibration inputs. Depending upon the particular model (X number), range
is 2 to 100 g's full-scale. Higher/special ranges are available. Over-range
stops are provided.
The accelerometer is an excellent replacement for the popular 2262
series of piezoresistive models, which are used in many flight-test and
automotive applications. The 10-32 mounting and electrical interface
of the 7292-XM1 accelerometer are similar to that of the 2262 series
and is compatible with most bridge instrumentation. Shunt calibration
simulation is included as part of the unit. Designed to provide years of
reliable service, the Model 7292-XM1 is packaged in a ruggedly designed,
25.4 mm hex. by 14 mm high stainless steel, hermetically sealed case.
A 74 mm shielded cable is provided.
The 7292-XM1 accelerometer operates from a 10 VDC source and
provides a high-level (±2 volt) differential, DC-coupled, low-impedance
output. The use of gas damping allows for the near-critically damped
characteristics found in the 2262 series of accelerometers without
thermally induced changes in frequency response. The 7292-XM1
accelerometer is insensitive to magnetic fields and requires a warm-up
time of only one millisecond.
