The
triaxial
kit
includes
three
ARS-01
or
ARS-01S
sensors,
three
CA-01
cable
assemblies,
and
a
triaxial
mounting
block,
which
becomes
a
6
degree-of-freedom
measurement
system
with
3
optional
linear
accelerometers
added
to
its
mounting
surfaces.
The
type of
linear
accelerometers
to
be
mounted
must be
specified
at time
of order
to
ensure
correct
mounting
holes
are
included
in
the
triaxial
block.
If
none
is
specified,
the
block
will be
supplied
predrilled
for use
with the
Endevco model 7264A/7265 series accelerometers. |

Notes:
1. Based on a
± 10V output voltage swing.
2. Based on a
± 3.5V output voltage swing.
3. Measured @
10 Hz.
4. The
standard frequency response of MHD sensors
can be extended significantly by the use of digital
filtering in post processing of signal data as
covered in ATA Sensors' application note AN-01.
|
5. Power spectral density flat to angular velocity over
specified bandwidth.
6. Percent change in Scale Factor per ºC @ 10 Hz.
7. Signal return connected to case (isolated from hex
base). Do not ground case to mounting
fixture to
avoid ground loops. |
