IS-V311AT Intrinsic safety vibration and temperature combined sensor

V311AT Intrinsic safety vibration and temperature combined sensor, V311A without temperature function. Lightning protection modle is V312.
Model  V311AT  is  an  intrinsic  safety  IEPE  accelerometer permitting  simultaneous  vibration  and  temperature measurements. 311AT features an annular shear ceramic crystal  which  exhibits  excellent  output  stability  over  time. The accelerometer incorporates an internal circuit with in a two-wire IEPE system which transmits its low impedance voltage  output  through  the  same  cable  that  supplies  the constant current power. Integrated thermal sensor transfer the temperature output by voltage signal. Signal ground is internal  shielded  and  isolated  from  the  outer  case  of  the 
unit. Polarity inversion protection for the amplify circuit is inherent  in  the  circuit  design.  The  welded  stainless-steel construction  provides  a  hermetic  housing.  The  standard MIL-C-5015 glass insulated connector provides long-term stability over the operating temperature range. In addition 
to adhesive mounting, 311AT has  ?-28 threaded holes for stud mounting on the test object. The V311AT provides wide frequency  response  and  shock  resistance,  which  is  ideal for  industrial  vibration  monitoring  under  incidental  shock environment.
