Ⅰ.Product Introduction

The YAW-300D microcomputer controlled flexural and compressive testing machine  is suitable for use in scientific research institutes, industrial and mining enterprises, etc. The testing machine automatically completes a batch of six test control modes according to the requirements of GB177-85 and GB17671-1999 "Methods for Testing the Compressive Strength of Cement Mortar", and has control modes such as constant velocity test force, constant velocity stress, and test force maintenance. It can also achieve bending test before constant stress compression test, truly achieving one machine with multiple functions. Implemented functions such as screen display of experimental data and curves, disk storage, and database management.

Ⅱ.Force measuring system

High precision amplifier and A/D converter, without dividing the entire process, real-time display of load, peak value, loading speed and strength;

PID closed-loop control strategy achieves constant speed loading and real-time display of loading curves;

Automatic interval timing and continuous testing;

Flexibility and convenience in querying and printing test results;

Software Description

(1) Main interface

(2) Result Query

(3)Report template

Ⅲ.Safety protection device

When the test force exceeds 3% of the maximum test force, overload protection and motor shutdown occur.
