Overview
Yunda YD-WTD bending stiffness tester (7-inch screen) is a special instrument for testing the bending stiffness performance of sheet materials such as paper, Cardboard, film, mica sheet, graphite sheet and composite. The instrument is equipped with a 7-inch touch screen operation interface, supports visual menu operation, and has High Accuracy measurement and multi-function adjustment characteristics.
Features
1. Measurement range: support (0~ 500) mN.m and (0~ 10000) mN two range selection
2. High Accuracy measurement: Precision +/- 0.1%, resolution 0.01mN
3. Multi-gear arm adjustment: span range 5-10-15 - 20-25-30 - 40 - 50mm, a total of 8 gears adjustable
4. Strong sample compatibility: support the old standard 38 * 70mm and the new standard 38 * 80mm sample size
5. Intelligent Adjustment: The equipment can be self-calibrated, standard calibrating tools and weight
6. Wide adjustable range of parameters: angular velocity 0.5~ 1000 °/min adjustable, bending time 5~ 35s adjustable, bending angle 1~ 90 ° adjustable
7. Convenient operation: 7-inch touchscreen visual menu operation, Sensor can be quickly replaced, equipped with modular integrated thermal printer
Principle
The instrument applies a bending force to the specimen through an adjustable lever arm to measure the stiffness performance of the material at a specific bending angle. The torque change during bending is detected by the High Accuracy Sensor, combined with the adjustable angular velocity and bending time parameters, to achieve accurate measurement of the bending stiffness of the material.
Applications
Paper, Cardboard, Film, Mica Sheet, Graphite Sheet, Composites
Standards
GB/T 23144、GB/T 22364、ISO 5628、ISO 2493
Steps
1. Select the appropriate Measurement range and arm span according to the test requirements
2. Prepare samples that meet size requirements (38 * 70mm or 38 * 80mm)
3. Set parameters such as bending angle, angular speed and bending time through the touch screen
4. Install the sample and test it
5. Read the test results and output the data through the thermal printer
6. Self-calibrate equipment using standard calibrating tools when necessary
Notice
• Ensure equipment is self-calibrated before testing
• Reasonable setting of bending time and angle parameters according to material characteristics
• Specimen size must meet standard requirements
• Ensure proper operation when replacing Sensors
• Regularly use standard weights for accuracy verification
• Avoid applying additional force to the sample during operation
