DDW Series computer Control Electronic Universal Hardness Tester Common Configuration adopts AC servo motor made in Taiwan and employs advanced chip integrated technology as well as the use of professional design of PCI data acquisition and control system, achieving a fully digital adjustment for testing force and deformation amplification as well as A/D conversion. The equipment adopts fully digital servo speed adjustment system and servo motor as the machine’s driving system,which has high precision speed adjustment and stable and durable working performance, meanwhile, it employs WINDOWS to control operation interface and supply data processing software, so as to realize the computer screen display for testing force, testing force peak value, beam displacement,test deformation and data curve picture. All the test can be completed by computer control.
Equipment’s Main Structure:
The whole structure is formed by the upper beam, the middle beam, the lower beam and the bottom panel, with two pairs of ball screw-rod and a vertical column. The full-digital AC Servo motor drives the Reducer and the synchronic gear belt, so as to drive the two pairs of high-precision and seamless ball screw-rod, and to make the beam move up and down.
Using Scopes:
DDW Series Microcomputer Control Electronic Universal Testing Machine (Normal Configuration Gate Type) is applicable for tensile,compression and bending tests of materials with relatively small test force, such as rubber, plastic, textile, waterproofing material, cable, network wire, metal wire, metal rod, metal plate and others. With attaching tools, it can also do compression and bending tests.
Application:
The equipment is applicable to the measurement and analysis of mechanical performance not only metal, non-metal material, but also composite materials. It is widely used in aerospace, petrochemical, machinery manufacturing, wire and cable, textiles, fibers, plastics, rubber, ceramics, food, medicine packaging, plastic pipes, plastic doors and windows, geotextile, film, wood, paper, metal materials and manufacturing. According to GB, JIS, ASTM, DIN, ISO and other standards, it can automatically strike the maximum test force value breaking force value, yield strength, upper and lower yield strength, tensile strength, compressive strength, elongation, tensile modulus, flexural modulus test data etc.
The built-in controller ensures the achievement of constant displacement control;
