The product description

A list,

Measurement and control system with high precision digital servo valve, have force closed-loop control function, can achieve load rate such as load or stress rate loading, such as high control precision, good reliability, electronic measurement is realized by using microcomputer, completion compressive strength test, the automatic calculation and print reports, widely used in the construction industry and testing units.

Second, the hydraulic system

Inside the fuel tank of hydraulic oil through the motor drive the high pressure pump into the oil, through the check valve, high pressure filter, differential pressure valve group, the servo valve, into the cylinder. Computer control signal to the servo valve, control the opening and the direction of servo valve, to control the flow of the enter the oil cylinder, realize the control of constant speed test force.

Third, the force measurement and control system

L amplifier and A/D converter with high precision, no step all the way, real-time display, load, speed and load, peak intensity;

L PID closed-loop control strategy was adopted to realize constant speed loading, real-time display the load curve

L automatic interval timer and continuous test;

L flexible query, print test results;
