Fully Automatic Compression Testing Machine
Fully Automatic Compression Testing Machine 3000 kN
Compression testing machine shall be fully automatic, controlled through touch panel based electronic display system as well computer through software. related to the size of the specimen and the expected load, and capable of providing the rates of loading prescribed in IS 516.Compression testing machine 3000 kN capacity with Servo Controlled based and automatic pace rate controller. Machine includes the features given is lS 14858-2000 (reaffirmed 2005).

In particular, the portable units, which are small in dimensions, sturdy and light in weight, make quality control testing possible in areas where commercial testing facilities are not available and where the transportation of larger and much heavier machines would be difficult. ENTEK Compression Testing Machines conform to IS: 14858(2000) and calibrated with an accuracy of ± 1 % as per the requirement of 1828(Class1).

Loading Unit:-
The loading unit is of fully welded construction having across head, base and solid side plates. The hydraulic jack is fixed to the base. The platens of the machine are hardened, ground and polished. The upper platen is provided with self-aligning action. To facilitate testing of various size specimens, suitable sized spacers are provided.

Set test parameters including load rate:
This machine having the provision for automatically turning the pump ON and OFF, controlling the set pace rate and switching the machine off under predetermined conditions. Machine having inbuilt intelligent pace rate controller. It is having a full three term proportionalintegralderivative controller continuously calculating an error value and controls the loading on the rock specimen using a high torque Stepper Motor and driver sets. The loading frame is a fully welded construction with a top crosshead, base and solid side walls with the precision ground hydraulic piston fixed to the base, one lower platen and one top platen with self-aligning action. The Pump control facilitated through PID controlled EDI. Pace rates parameters can be set digitally and cannot be regulated manually. Machine able to operate as standalone with digital indicator unit as well with dedicated data management and analysis software installed in a desktop PC or laptop.

Peak load, Peak Stress,Unique record no displayed on the digital indicator, MS-Window based reputed make computer with compatible configuration to run the analysis software. Suitable for Testing above mentioned parameters for HQ, NQ & BQ size samples in Compression.
