LFY-402B Rotating Machinery Friction Electrostatic Tester (Computer Type)

Main purpose 
Under laboratory conditions, it is used to evaluate the static properties of fabrics or yarns and other materials that have become charged through friction.
Technical Specifications: 
1. By adopting advanced numerical control technology and the friction-type electrostatic testing method with rotating wheels, the voltage of the friction belt and the attenuation time can be automatically measured. The amplifier equipped with high-precision electrostatic sensors enhances the testing accuracy, and the operation is safe and reliable. 
2. The instrument consists of a testing machine and a computer detection system. The static attenuation ratio can be adjusted, thereby expanding the testing range. 
3. The test probe is designed with a positioning block for limiting, which makes positioning very convenient. 
4. Static voltage testing range: 0 - 10KV, accuracy: ≤ ±1% 
5. Drum dimensions: Outer diameter (150 ± 1) mm, Width (60 ± 1) mm, Rotation speed: (400 ± 1) r/min 
6. Friction time: Adjustable from 0 to 99.99 seconds per meter per hour within a range of ±0.01 seconds. Half-life time range: 0 to 99.99 seconds per meter per hour within the same ±0.01 second range. 
7. Size of the friction cloth: (150 ± 1) mm × (25 ± 1) mm, pre-applied tension: (4.9 ± 0.1) N 
8. Sample size: (80 ± 1) mm × (50 ± 1) mm 
9. Dimensions of the main unit: 450mm × 315mm × 320mm; Dimensions of the electrical control box: 450mm × 256mm × 185mm 
10. The computer controls the test process. The peak voltage is automatically locked. The peak voltage of electrostatic charging due to friction, the friction voltage and the attenuation curve can be displayed in real time. The test report can be stored, displayed and printed out. 
11. Working power supply: AC 220V ± 10%  50Hz  200w 
12. Weight: Approximately 50 kilograms
