ST 9000 DPRC series Micro Controller based Compression Testing Machine is based on an intelligent pace rate controller. This facilitates automatic pace rate control, data logging, data printing, load hold etc. It has a full 3 term PID feedback control which uses a high torque Stepper Motor. Is consists of a Loading unit, an Electrically Operated Hydraulic Pump & an intelligent pace rate controller. The operation is user friendly with a menu driven interface

System Description

The loading frame has a fully welded construction with a top crosshead, base and solid side walls with the precision ground hydraulic piston fixed to the base. The machine’s platens come with a self- aligning action and suitably sized spacers to accommodate a variety of different sizes of specimen. The two speed pump allows the fast approach of platens, for daylight closure and also allows automatic, precise control over the load application; a pace rate bar on the display gives operator feedback on the loading rate. The controller incorporates a four line digital display and features the integral load pacing bar display, maximum load and stress result display and a RS 232output. Results from 1000 completed tests can be stored in the memory and these results can be in English, Metric or SI units. The Calibration range of the machine is from 10% to 100% of the machine capacity, over which range the accuracy is ±1% of the applied load
