This is a two
axis sensor
array comprised
of two ARS-04
type sensors in
a mounting block
plus an
amplifier and
signal
conditioning
board mounted
and hermetically
sealed in an
aluminum block.
The Dynacube® 2
-axis has three
surfaces which
can be used for
mounting three
linear
accelerometers
to make a linear
and angular
motion sensor
array.
Linear
accelerometers
may be supplied
by ATA or
customer
supplied.
Scale
Factor
(Sensitivity)
--
The
standard
scale
factor
for
the
ARS-04
sensor
used
in
Dynacube®
products
is
100
mV/(rad/sec).
We
can
provide
custom
scale
factors
to
order
over
a
range
of
values.
Any
other
desired
scale
factor
must
be
specified
in
mV/(rad/sec)
or mV/(deg/sec).
However,
increasing scale
factors beyond
this standard
value will
result in a
reduction in
frequency range.
Both
sensors in the
Dynacube® 2
-axis will
supplied
to the same
scale factor
unless otherwise
specified in
custom order
form.
Range
--
The
output
signal
range
is
determined
by
dividing
the
maximum
output
voltage
by
the
scale
factor.
A
higher
scale
factor
will
result
in
a
more
limited
range.
A
standard
Dynacube®
with
a
100
mV/(rad/sec)
scale
factor
and
an
output
power
voltage
of
±10
V
will
have
an
angular
velocity
range
of
±
100
rad/sec.
Input
Voltages
(Excitation)
--
Standard
input
voltages
of
+
5/-5
Vdc
to
+15/-15
Vdc
are
used
for
the
Dynacube®
2
-axis.
When
the
applications
require
operation
from
a
single
power
source
such
a
+12 Vdc,
an
ILC
can
be
used
to
generate
the
dual
voltage
inputs
to
the
two
sensors.
Signal
Conditioning
and
Power
Supply
Requirements
--
The
Dynacube®
may
be
operated
without
a
separate
power
regulator
or
in-line
signal
conditioning
unit
if
the
standard
customer
power
supply
is
well
regulated
and
without
noise,
and
if
the
sensor
output
cables
are
of
proper
impedance,
not
more
than
15
to
20
feet
in
length,
and
not
subject
to
induced
noise
from
external EMI
sources.
ATA
supplies
optional
cables
for
the
Dynacube®
which
have
the
proper
connectors,
use
Teflon®
insulated
wire
with
twisted
pairs
and
heavy
metal
shielding
to
minimize
noise.
Cables
and
Connectors
--
Two
cable
connection
options
are
offered
for
the
Dynacube®
2
-axis.
Cable
CA-04A
is
specified
when
no ILC
is
used.
Standard
cable
length
is
approximately
7
meters
(23
feet)
and
this
is
supplied
with
the
sensor
mating
connector
on
one
end
and
un-terminated
pigtail
at
the
other
to
allow
for
the
customer
to
add
their
own
connection
to
measurement
equipment.
The
cable
CA-05A
is
specified
when
an
ILC
box
will
be
used.
This
is
a
5.5
meter
cable
which
goes
from
the
sensor
connector
to
the
ILC
box. The ILC box utilizes
a
military
specification
AirBorn®
connectors
(male)
M
series.
The
output
side
of
the
ILC
box
uses
corresponding
CA-03A
cable
which
is
1.5
meters
in
length,
has
AirBorn®
6
pin
“M”
series
connectors
at
the ILC
box
end,
and
pigtails
at
the
other
end
to
allow
customer
interface
connectors
to
be
added.
Custom
machined
connector
housings
allow
the
connectors
to
be
locked
to
the
ILC
using
screws
provided.
In-Line-Converter
(ILC)
--
modules
are
offered
by
ATA
to
provide
a
complete
measurement
solution
for
power
regulation
and
signal
conditioning
/
amplification.
The ILC
modules
applicable
to
the
Dynacube®
2
-axis
are:
DYNA-ILC
--
This
is
a
three
sensor
ILC
unit
which
provides
a
DC/DC
converter
and
signal
conditioning
/
amplification
in
a
single
unit
or
a
combination
of
these
three
functions.
Units
can
only
be
configured
at
the
time
of
manufacture,
since
they
are
fully
encapsulated
with
special
epoxy
resins
for
ruggedness
and
durability
at
assembly.
Signal
conversion
and
gain
options
are
exclusive;
only
one
or
the
other
may
be
specified.
-
As
a
signal
conditioner,
the
ILC
can
covert
the
standard
angular
velocity output
of
the
sensor
to
an
angular
acceleration
signal.
(The
calibration
data
sheet
provided
with
the
DYNA-ILCxA
will
specify
the
volts-per-volts
output of
the
acceleration
signal
at
10
Hz.
and
at
100
Hz.
This
is
a
differential
circuit.
The
gain
at
100
Hz.
will
be
ten
times
that
at
10
Hz).
The
order
number
for an
ILC
for
signal
conversion
from
velocity
to
acceleration
has
the
letter
“A” as
the
second
ILC
option
indicator.
The
output
signals
of
both
sensors
will
be converted
unless
a
custom
order
configuration
is
specified1.
|
-
As
a
power
converter,
the
ILC
will
allow
the
user
to
supply
a
single
excitation
voltage
(typically
+10
to12
Vdc)
and
provides
a
bipolar
voltage
(±13.2
Vdc)
output
to
the
two
sensors.
The
order
number
for
an
ILC
for
power
conversion
has
the
letter
“D”
as
the
ILC
first
option
indicator.
If
no
power
conversion
is
desired,
the
letter
“N”
is
specified.
|
-
As
an
amplifier,
the
ILC
will
supply
an
amplified
signal
with
gain
of
1
to
1000
times
normal
signal
output.
Standard
versions
are
available
in
1,
10,
100,
or
1000
times
gain.
The
order
number
for
an
ILC
without
additional
gain
(1x)
is
“F”.
The
order
number
for
an
ILC
for
signal
amplification
from
1
to
10x
has
the
letter
“G”
as
the
second
ILC option indicator. For gain from 1 to 100x, the letter “H” is specified. For gain of 1000x, the letter “L” is specified. (See examples below.) Note that either gain or acceleration signal output can be supplied, not both. The gain for both sensor output signals will be the same unless a custom order configuration is specified1.
