Automatic Compression Testing Machine :
ZI 2042

The Automatic Compression Testing Machine is a fully automated version of the manual / semi automatic Compression Testing Machine. The machine is available in 500kN, 1000kN, 2000kN, 3000kN, 5000kN Ranges. It has provision for automatically turning the pump on and off, controlling the set pace rate and switching the machine off under predetermined conditions. The Control release the pressure at the end of every run and reinitializes the machine at the beginning of every test. The pace rate is maintained by means of full three term PID feedback control using high torque stepper motors and drivers sets. Data acquisition, storage, management and analysis are all fully automated. The load resolution is for is 0.1kN for machines upto 1000kN capacity & 1.0kN for the 2000kN, 3000kN & 5000kN Machines.
The complete unit comprises of:
Loading Unit : The loading unit is of fully welded construction having a cross 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 size spacers are provided complete with ball seating arrangement.
Pumping Modlule : This has a two-speed hydraulic motor driven pump and a bonded strain gauge based pressure transducer.
Digital Head :
This contains all the electronic system for controlling the pace rate, acquiring and storing test-data, communicating with the computer and operating the load-release motor.
RS 485 to RS 232 Convertor : This convert data transmitted by the digital head to a form recognized by the computer.
The system is compatible with any computer with the following:
Specification :
P-IV and above, 1.9Ghz
256 Mb RAM
Intel Chipset with on-board graphics card.
40 GB HDD
1.44MB FDD & CD ROM DRIVE

Strain Control with the Automatic Testing Machine
In addition to measuring the stress on the cement specimen, a version of the machine is also available with the option of measuring the strain on the sample. This is achieved by installing an L.V.D.T. to measure the compression of the sample form which the strain can be calculated. With this option, the software features of the Automatic Compression Testing Machine are expanded to include the following:
1. Compression Vs time Plot
2. Strain Vs Time Plot
3. Stress Vs Strain Plot
4. Calculation of Young is Modulus of the sample

Flexural Strength Measurement with ACTM
In addition to compression strength an attachment for flexural strength beam can also be supplied at extra cost. This is accomplished by providing a frame for testing flexural strength alongwith the dedicated software which can be used as an attachment to the existing system. The software features of the flexure attachment include the provision for calibration.
