UTM series computer control universal testing machine is used in light duty tensile, compression, and bending test applications for metallic, non-metallic, and composite materials. The PC controlling system is able to realize the close-loop control of the parameters such as loading force, specimen deformation, and crosshead stroke etc.
Application:
UTM series computer control universal testing machine is used in light duty tensile, compression, and bending test applications for metallic, non-metallic, and composite materials. The PC controlling system is able to realize the close-loop control of the parameters such as loading force, specimen deformation, and crosshead stroke etc. The system realizes the screen display, online diagram drawing, testing curve changing, pile curve collation and auto analysis of test results, creation of test report. Especially, the application of the control mode can be manual control or computer programming control, which makes the cyclic tests become available.
