Scope of application
It is used to test the smoothness of metal, injection molding and nylon zippers.
Technical parameter
1. Force measuring range: 30 N
2. Load accuracy: ≤±0.5% F•S
3. Effective test length: 80mm~220mm
4. Stretching speed: (1250±50) mm/min
5. Return speed: (1250±50) mm/min
6. Power supply: AC220V, 50W, 50Hz
Instrument characteristics
1. Force measurement system: it is composed of high-precision force sensor, 12-bit high-precision A/D conversion board and PC computer force measurement.
2. Tension sensor protection system: When the tension is greater than the sensor, the computer quickly judges to stop the tension system, indicating that the zipper pull force has exceeded the force measurement range.
3. Automatic positioning function: the photoelectric isolation switch input/output board is adopted, and the fixture can be positioned arbitrarily at 80-220mm extension under computer control.
4. Automatic processing of test data and display of test report and strength---elongation curve;
5. Computer test software function:
A: Test date, serial number, material, model, displacement, test unit name, manufacturer and other test data.
B: Display and save test data: maximum strength, minimum value, average value, CV value.
