This is a + 10 Vdc only input, three-axis sensor array comprised of three ARS-04 sensors in a mounting block plus a voltage conditioner, an amplifier and signal conditioning board mounted and hermetically sealed in an aluminum cube.  The Dynacube™-S has three surfaces which can be used for mounting three linear accelerometers to make a 6 degree-of-freedom sensor array.  Linear accelerometers may be supplied by ATA Sensors or customer supplied.

Scale Factor (Sensitivity) -- The standard scale factor for the sensors used in the Dynacube™ –S is 35 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.  All three sensors in the Dynacube™-S 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™-S with a 35 mV/(rad/sec) scale factor and an output power voltage of ±3.5 V will have an angular velocity range of ± 100 rad/sec in each of the three axis.

Input Voltages (Excitation) -- Standard input voltage of + 10 Vdc only is used for the Dynacube™-S.  An internal voltage regulator converts the single voltage input to the dual voltage required by the sensors in the Dynacube-S .

Signal Conditioning and Power Supply Requirements -- The Dynacube™-S may be operated without a separate 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 Sensors 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™-S Triaxial. 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 AirBorn^® “M” series connector on one end and un-terminated pigtail at the other to allow for the customer to add their own connection to measurement equipment. Two screws are supplied with the cable CA-04A to lock the connector to the sensor.

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 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 Sensors to provide a complete measurement solution for power regulation and signal conditioning / amplification. The ILC modules applicable to the Dynacube™–S triaxial are:

DYNA-ILC -- This is a three sensor ILC unit which provides signal conditioning or amplification in a small rugged in-line module. 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.

•      The DYNA-ILC power conversion option is not applicable for the Dynacube™-S which requires only a single voltage input.  
  

•       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 all three sensors will be converted unless a custom order configuration is specified.1.
  

•       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 all three sensor output signals will be the same unless a custom order configuration is specified.1.
