Micro Controller Based Compression Testing Machine

Micro Controller Based Compression Testing Machine:

Operation of Micro Controller based Compression Testing Machine are controlled by an intelligent Pace Rate Controller. This facilities Automatic Pace Rate Control, Data Logging, Data Printing, Load Hold etc. It has a full 3 term PID feed back control which uses a high torque Stepper Motor. It consists of a Loading Unit, an Electrically Operated Hydraulic Pump and an Intelligent Pace Rate Controller. Micro Controller based Compression Testing Machine is available in all models from 50kn to 3000kN capacity. In addition to all the features of Compression Testing Machine with digital display, this machine has automatic pace rate control with the facility of data logging, storage & printing for analysis. The operation of the machine is detailed in the operating manual supplied with the machine. The operation is user friendly with a menu driven interface and prompts for an operator.

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-alinging action.
