RU Spec ½Ã½ºÅÛ RU SpecÀ¸·Î °Ë»ç °¡´ÉÇÑ °Íµé
 
Features
 

  Calculates Elastic Constants and associated physical constants (moduli and Poisson's Ratio)
    to accuracies of better than 0.1%, depending on sample preparation and uniformity
  Calculates materials' sound velocities
  May be used for isotropic, cubic, hexagonal, tetragonal, and orthorhombic crystal symmetries
  Precision Sample Holder mounts parallelepipeds with differing side lengths from minimum of
    about 2 mm to a maximum of about 20 mm.  (Aspect ratio not to exceed 5 for any two sides)
  Acquisition software for measuring resonance frequencies
  Analysis software for calculating initial resonant frequencies and for iterating calculated to
    measured to calculate elastic constant values
  Computer with internally mounted transceiver


 
Specifications
 
 Processor  133 MHz Pentium (Higher speed CPU¡¯s may be used, depending on supplier
 availability, even though the RU Spec does not require higher speeds)
 Frequency Range  1 kHz to 5 MHz, nominal
 Precision Parallelepiped
 Sample Holder
 Two piezoelectric transducers (one driver and one receiver) with a temperature
   range of 0¡ÆC to 95¡ÆC.
 The transducers are mounted to provide precision x-y-z geometry adjustment
   for optimizing individual resonant amplitude and minimizing deformation of
   parallelepiped sample.
 A clear, environmental cover is provided to protect from external noise during
   measurements and dust when not in use.
 Cabling to computer/tranceiver included.
 Internal Modem  33.6 or 56.6 kps
 Hard Drive  1.6 Gigabyte (A higher storage capacity hard drive may be used, depending on
 supplier availability of the 1.6 Gigabyte drives. The RI-1000 does not require a hard
 drive with storage greater than 1.6 Gigabytes.)
 Floppy Drive  3.5 inch standard 1.4 Megabyte
 Dimensions  17" x 17.5" x 7" plus monitor
 Power Requirements  100-120 volts or 200-240 volts, 50/60 Hz, 300 watts with 15 inch monitor
 Operating Temperature
 Range
 0¡ÆC to 50¡ÆC
 Storage Temperature
 Range
 0¡ÆC to 63¡ÆC
 Relative Humidity
 (Operating and Storage)
 5% to 95% with the ambient temperature above the dew point.
 (Condensation is to be avoided.  Although the RU Spec may be stored at 0¡ÆC,
 immediate removal of the instrument from an environment at this temperature to an
 environment at a higher temperature may cause unwanted condensation, even
 though none of the nominal specifications have been violated.  If such storage
 conditions occur, the User should wait sufficient time before turning the instrument
 on so as to allow any possible condensation to evaporate.)
 Compliance  The RU Spec complies with the European EMC Directive and has received CE
 certification.
