Servo Electromechanical, Creep Testing Machine, can work on tension-compression, bending and long term-creep tests and on both displacement/deformation mode and load control mode (with and without extensometer - optional).Two column rigid construction.

Load measurement and control, with a special creep type load cell of class 0.5 for long-term tests, 1 kHz data accusation Close-loop electronic controller, Crosshead moving speed (mm/min): 0.001-250.

The electronic control unit of system is with 1000 samples per second data acquisition speed. Accurate synchronization between frame and sensors will be done/controlled by advanced PID or close loop configuration. Electronic control unit has total 5 channels (2 internal, 3 external (*optional) and 1 RS232/485). Due to these channels electronic control unit can control 5 no. sensors at same time.

Electronic control unit is feasible to attach and control video extensometer, laser extensometer, LVDT, automatic extensometer, strain gauge, load cell, SSI and TTL type sensors (Sensors are optional). Special Eeprom sensor plugs can store calibration and sensor data inside it. Due to this feature control unit can read sensor and calibration data even if user change it with new unit.

User can read and control each attached sensor with control unit, for example; 2nd load cell, LVDTs and extensometers. can perform load and displacement controlled test, position measurement and control with position encoder of 1 micron resolution, Load channel with a resolution of 20bit, adjustable displacement control in between 0.001 - 250 mm/min, testing software, 32 user defined result parameters (connected to load and position), result can be transferred to Excel format(Raw Values). It has periodic saving function for long-term creep tests.
