China Wholesale Magnetic Damp Factories – LMEC-21 Vibrating String Experiment(string sound meter) – Labor
China Wholesale Magnetic Damp Factories – LMEC-21 Vibrating String Experiment(string sound meter) – Labor Detail:
Main Experiments
1. The relationship between string length, linear density, tension and standing wave frequency is studied;
2. The propagation velocity of wave is measured when the string vibrates;
3. Inquiry experiment: the relationship between vibration and sound; 4. Innovation and research experiment: Research on the electrical mechanical conversion efficiency of standing wave vibration system.
Main technical parameters
1. A pair of electromagnetic induction sensor probes, receiving and transmitting can work interchangeably; Sensitivity ≥ 30dB;
2. The tension is adjustable from 0.98 to 49n, and the minimum step value is 0.98n to reduce the influence of friction;
3. Steel string: length 700mm, continuously adjustable, three kinds of linear density, not easy to break string;
4. Signal source: frequency range: frequency band I: 15 ~ 200Hz, frequency band II: 100 ~ 2000Hz; Frequency measurement accuracy: ± 0.2%; The amplitude is adjustable from 0 to 10vp-p;
5. It can also be equipped with DDS signal source, and innovative experiments can be added. For details, please contact us;
6. The instrument needs to be equipped with dual trace oscilloscope(Not include).
