WA-D Microcomputer-controlled Electrohydraulic Proportional Servo Universal Tester

WA-D Microcomputer-controlled Electrohydraulic Proportional Servo Universal Tester
ProductNo: 010
ProductModel: WA-D
Description：Applications:elongation tests, compression tests, bending tests, shearing tests, etc.,

Maximum test force (N):100k-2000k


  • Description
  • Technical Specifications
  • Product Literature
This model only one type ,WA-D,with its cylinder mounted on the lower part. It is the optimal choice for replacing conventional hydraulic universal testers. It can be used to conduct elongation, compression, bending, shearing, peeling and tearing tests, as well as testing, analysis and research on various metallic, nonmetallic and composite materials, and structural members and finished products made of these materials. Any testers with a rating above 100KN have a lower-mounted oil cylinder and are equipped with an automatic hydraulic clamping apparatus, which fundamentally solves the type of problem in which the test sample slips out of position and greatly reduce the working strength of operators.
This machine adopts a fully digitalized computer measurement control system and incorporates a powerful user software package to perform data collection, data storage, data processing and test result printing. It supports multiple force sensors, multiple deformation sensors, running state control, and input of test parameters, and can adequately satisfy the requirements for various test methods adopted by the tester user (such as GB, ISO, DIN, ASTMD, JISK, etc.) when testing different materials or finished products. It can realize automatic force value calibration and automatic deformation calibration; can perform continuous testing by setting the test conditions for a batch of test samples only once; can modify parameter computation and customize test reports conveniently; can automatically calculate parameters such as the maximum test force, yield strength, upper and lower yield points, tensile and compression strengths, tensile (compression) stresses, elongation (compression) rates, elastic modulus, bending deflection, etc.; can display test curves in a real-time manner and store and analyze measured data; can store and retrieve test results freely; enables selection of various types of curve for reanalysis; can compare test curves in the same group by distinguishing the color of each curve upon superposition; allows the user to use the mouse to select parameter points on curves, select parameter points on curves, select a curve display mode, zoom in on local sections of curves, print curves, and generate a simulated WYSIWYG report display on the screen before printing a report; and, possesses automatic rupture judgment function and multiple protective modes. All these features guarantee safe and reliable running of tests.
