1. Introduction to WDW-300G microcomputer control electronic universal test machine

The WDW-G series desktop microcomputer control electronic universal testing machine has the characteristics of compact structure and simple use, and can be used in the force test of materials such as tensile, compression, bending, shear, peeling, tearing, etc. The cross beam in the main machine adopts high-precision guide rod guide, which has high rigidity and good linear motion characteristics. A wealth of accessories such as fixture tools, load sensors, deformation measurement sensors, etc. can meet almost all customer needs. The flexible and easy-to-use testing software makes the user's testing process easier. The experimental solutions cover plastics, metals, automobile industry, building materials, textiles, paper and cardboard, food and packaging, composite materials, etc.
2. Features of the host of the WDW-300G microcomputer control electronic universal test machine
The United States imported high-precision sensors with high accuracy and good stability.
The middle beam adopts four guide rods and graphite self-lubricating sleeves to guide. The strong guide light bar increases the transverse rigidity of the equipment and ensures linear movement of the beam. It enables accurate alignment of crossroads, reduces differences in measurement data, and produces good overall accuracy;
The high-precision ball screw pair makes the transmission more stable. The whole machine has high rigidity and smooth operation;
Extra-large workbench and ultra-wide span to meet customer needs;
All-aluminum alloy cover and all-aluminum alloy protective cover have beautiful appearance and convenient operation.
3. Features of WDW-300G microcomputer control electronic universal test machine controller

(I) External independent controller

The new generation of static test machine special controller integrates measurement, control and transmission functions, and highly integrates signal acquisition, signal amplification, data transmission, and servo motor drive units; it provides a new solution for the measurement, control and operation of test machine, and USB data transmission fully supports notebook computers, tablet computers, and desktop computers; it is an important part of the development of test machine technology.

The external handheld controller adopts a 320*240 LED display, which can quickly adjust the test space. It also has functions such as test start, test stop, test clearance, etc., displays the operating status of the equipment and test data in real time, making the sample clamping more convenient and simpler to operate.

(II) Universal testing machine measurement and control software

The universal testing machine measurement and control software adopts DSP technology and neuron adaptive control algorithm to realize a variety of closed-loop control modes such as constant-rate testing force, constant-rate beam displacement, and constant-rate strain. The control methods can be combined and switched smoothly; it has a networked interface, which can realize data networking and remote control functions.
