Dimensional Gaging Probes DGP Series

The  DGP  Series  Dimensional Gaging Probes by Alliance Sensors Group are AC-LVDT  based,  spring-loaded  linear  position  sensors  designed for high precision  dimensional  gaging  applications.  Widey  used  in  the  automotive, aerospace,  and  medical  industries  for  machined  parts  manufacture,  Gage  R&R,  and  CpK data,  the DGP Series has  the precision necessary  to make measurements  to  uphold six-sigma  programs.  Available  in  three  ranges, the DGP  Series  spring  loaded  LVDT  has  an  8mm  diameter,  IP-65  rated  housing  that  is  slightly  shorter  than  most  competitive  units.  A  light  spring  force  of  less  than  1.25 lbs/inch  holds  the  DGP  probe  in  contact  with  the  part  but  is   light enough not to deform the product. Precision ground bearings and an anti-rotation  pin  allow  the  DGP  to  hold  sub-micron  repeatability  and  resolution.  A  rubber  boot  over  the  probe  shaft  keeps  contamination  out  of   the linear bearing. Alliance Sensors Group offers the SC-100 DIN-rail signal conditioner  for  use  with  the  DGP  Series  LVDT  probes,  permitting  the  user  very  easy push button  calibration.  The  SC-100 excites  a  DGP  with  the  proper  AC  voltage  and  frequency,  and  then   demodulates   and   amplifies  the  DGP’s   AC  output   to   produce   the   user’s   choice   of   sev- eralanalog   DC   voltages   or   4-20   mA   current   output   signal.
