Brinell hardness tester quotation

Control principle:

Digital Brinell hardness testerAdopting the world's most advanced fully automatic closed-loop sensor control technology, the ball bearing screw is directly driven by a stepless servo motor to apply force, and the force process and magnitude are feedback in a closed-loop manner by a force value sensor to micro level, permanently eliminating the overloading or underloading fluctuations caused by hydraulic or motor deceleration errors, or spindle blade friction in traditional weight lever amplification loading systems with increasing use time

To avoid loading errors caused by changes in the elastic coefficient of the spring loading system due to cyclic use Greatly improve accuracy and repeatability The high-precision indentation depth grating displacement sensor is located on the same vertical centerline as the spindle and is connected to the force sensing feedback loop and controller in a closed-loop manner. It is further subdivided by an amplifier to achieve sensitivity and resolution of up to 0.1 micrometers The program software has an automatic correction function for small errors in hardware systems such as force, displacement, and optics
