ARS-06 Triaxial Unit

 


The triaxial kit includes three ARS-06 or ARS-06S sensors, three CA-06 cable assemblies, and a triaxial mounting block, which becomes a 6 degree-of-freedom (DOF) measurement system with 3 optional linear accelerometers added to its mounting surfaces.  The ARS-06S uses a single-sided power supply commonly used in automotive crash testing. 
 

 

The type of linear accelerometers to be mounted must be specified at time of order to ensure correct mounting holes are included in the triaxial block.  If none is specified, the block will be supplied predrilled for use with the Endevco model 7264B/7265 series accelerometers.
