Ⅴ、Features of TENSON Software:

Note: Software Interface

1、Multiple pressure sensors can be configured according to user requirements, with the ability to switch between them as needed.

2、A professional testing machine software with strong versatility. The software provides users with dozens of standards or test methods for metals and non-metals, and custom standards or test methods can also be created based on user requirements.

3、The program uses an open database structure, allowing users to modify and add custom items as needed. Users can also freely edit various report formats according to their needs.

4、Modular Design: TENSON adopts a modular design, dividing the software into several modules, including:

• Test Module

•Main interface of the test software

•Test Control Center

•Parameter Management Permissions: Non-debugging operators cannot access the parameter debugging module

•New Data Module: Allows for creating single or bulk test data parameters

•Curve Analysis Module: The software can automatically mark characteristic points on the curve and perform operations like zooming and browsing

•Data Query Module: As long as you know any parameter of the test, you can find the required test data among thousands of test records

•Equipment Parameter Debugging Module: The control unit for the device control parameters

•Report Printing Module: Allows users to edit test reports as needed

•Control Program Editor Module: Users can flexibly customize specific control programs according to actual needs

5、TENSON is equipped with various auxiliary programs:

•Debugging Toolbox Configuration Program: It allows users to change the system’s configuration parameters when opened.

•Batch Processing Configuration Program: It enables statistical processing of test data with the same batch number, date, or other common identifiers.

•Report Processing Program: Provides a report editing program that allows users to freely modify the report format.

Multi-step control includes metal tensile testing and others. A variable structure PID control algorithm is used to adjust the loading process, with constant speed control error ≤ 1% and pressure-holding control error ≤ 1%. A “Control Program Editor” software is provided to professional users, enabling them to flexibly customize specific control programs according to actual needs.

11、Worm gear transmission mechanism: Used to adjust the test space, with the feature that the screw shaft does not need to rotate when adjusting the test space. This separates the transmission system from the positioning system, ensuring the geometric center and force center of the loading system are completely aligned, which guarantees the coaxiality of the upper and lower clamps and the durability of the main unit. The unique screw backlash elimination mechanism ensures continuous test loading.

12、Multiple control modes: Includes force, displacement, and deformation three-loop control, multi-step control (including metal tensile tests), and professional users can use the “Control Program Editor” software to flexibly customize specific control programs.
