LBTXF-8420 Microcomputer-Controlled Sponge Indentation Hardness Tester

Description

Product Introduction:

It is primarily applicable to soft polymeric foam materials such as sponge and foam, enabling standardized testing of samples of specified dimensions under the A‑, B‑, and C‑methods prescribed by national standards, as well as under other test conditions. This allows for the determination of indentation hardness indices, indentation hardness characteristics, indentation hardness verification, and compressive stress measurements. Testing is conducted in accordance with international standards including GB, ISO, JIS, ASTM, and DIN, with corresponding test data provided.

Main Overview:

It consists primarily of two major components: the testing host and the control system. The instrument is computer-controlled, enabling fully automated data acquisition in accordance with standard requirements. All operations are performed via software, ensuring convenient and straightforward testing. It can rapidly and accurately collect and process various data during the test, as well as store, display, and print the results.

Main features of the equipment:

I. Rack Features:

1. Driven by an imported AC servo motor, it offers high precision and fast response.

2. U.S.-imported sensors, with high precision and excellent stability.

3. The middle crossbeam is guided by a precision smooth shaft, ensuring high machine rigidity and smooth operation.

4. An exceptionally wide test width, fully meeting customer requirements.

5. Arc-shaped front cover design for an aesthetically pleasing appearance.

II. Controller Features:

1. The measurement resolution for force and deformation reaches 1/500,000 of the full-scale range.

2. The sampling frequency can be as high as 1000 Hz.

3. An advanced neuron‑based adaptive PID control algorithm is employed, enabling closed-loop control of all measurement channels.

4. Features sensor self-identification.

5. It features comprehensive standalone capabilities for testing machine measurement and control as well as data processing, while also offering robust and fully integrated network management functions.

6. It offers a variety of cutting-edge, powerful human–machine interaction methods, including true-color LCD display, touchscreen operation, wireless remote control, and voice prompts.

III. Software Features:

1. The test plan is open-ended, allowing customers to customize it according to the requirements of the applicable test standards.

2. Dynamic Display: Force, displacement, velocity, deformation, and test curves are displayed dynamically on the screen in real time.

3. The test report is open‑ended, allowing customers to customize the report format according to their needs and generate a variety of personalized reports. Additionally, reports can be exported to Excel files, facilitating secondary editing by users.

4. Robust permission management capabilities allow administrators to grant access to specific software functions based on the user’s role and level of expertise, significantly reducing the risk of equipment malfunctions caused by operator error.

5. Powerful data management capabilities enable real-time data acquisition and processing for 16 analog channels, 8 digital measurement channels, RS‑232/485 bus‑based measurement devices, and CAN‑bus measurement devices.

6. Enhanced data query functionality allows users to perform combined searches based on test result information such as ID, date, and test protocol name.

7. Rich curve-analysis capabilities: the software automatically marks characteristic points on the curve and supports operations such as zooming in and out at arbitrary magnification levels, as well as curve traversal. During testing, it can display multiple types of test curves in real time; after the test is completed, users can manually define upper and lower yield points, greatly facilitating data analysis.

8. Custom parameter unit functionality. Users can configure units as needed. The software automatically performs conversions between standard and custom units for all sampled data, result calculations, report generation, and more.

9. Equipped with software limit protection, travel limit protection, and full-scale overload protection.
