Main functions and features:

YAW-300DThe microcomputer controlled constant stress compression and bending testing machine is a precision testing machine developed on the basis of emphasizing basic performance. Has excellent operational performance.

a) Adopting advanced AC servo motor speed control drive system, speed ratio1：10000, can be adjusted according to the needs of loading speed0.01-50mm/minRealize any upward speed of the pressure plate within the range;

b) Fully mechanical structure, from servo motor to servo reducer, adopting fully sealed structure, no need to replace lubricating oil during use, no pressure oil leakage or proportional valve blockage;

c) The host design follows ergonomics standards to make operation simple, convenient, and fast. Measurement and control with high precision and intelligence

a) Fully leveraging the advantages of microcomputers, reducing the hardware of electronic control systems, and integrating all electrical components into two modules, greatly improving product reliability;

b) Exceeding a certain range of the maximum test force (overloading this gear)2-5%）When the piston touches the limit, it can be stopped immediately;

c) All measurement data can be permanently saved for future observation; The measurement and control of experimental force and displacement are centralized on the test interface of the microcomputer, which is intuitive and easy to operate.
