Loading Frame  
Computer      Controlled      Electromechanical      loading      frame      suitable      to      conduct Tensile / Compression / Bend/Flexure/Creep    test    on    Geosynthetic    materials    (Geotextile, Geomembrane, Geogrid, Geonet, etc.) and also suitable for different materials such as Metals, Rubbers,  Cables,  Fabrics,  Tapes,  Thread,  Plastic,  etc.  conforming  to  testing  procedure  laid down in respective ASTM/ ISO standards. 
The  Load  frame  is  floor  standing,  with  crosshead  driven  by ball  screw  coupled  to  a highly sensitive servo motor. A servo motor controller drive fitted in the frame that monitor over/under voltage, current and temperature. The design of the frame is such that it allows the single test zone for both tension and compression tests. It fitted with a  sensor  to  set  the  initial  position  of  the  moving arm.  The frame  have  in  built  safety features as a protection for over travel (Upper and Lower Limits) and over load. The upper and lower crosshead limits can be set at any point within the frame’s clearance with an ease. An emergency  switch   provided  to  shut  down  the  system  incase  of  any  accident  or malfunctioning
Electronic Control Unit and Data Acquisition
Signal conditioning - two-function high speed system. The channels is Load and Displacement directly calibrated in their respective  engineering  units.  Load  indicated  in  terms  of  N/kN  with  a  resolution depending upon the capacity of selected load cell and displacement in mm with resolution of 0.01mm.  The  load being  measured  by  the  Load  cell  and  displacement  being measured  by  Rotary  Encoder.  The  system receive  the  output  signal  of  the  both  the channels as its input and amplify the same. The data of both the channels of machine can be transferred to computer and can be online monitored in the software.
