Kundt's tube with analog output

Product advantages

• Study of stationary waves
• Recording of the raw signal and the envelop curve
• Computerization of location and signal measures

Full description The apparatus is made up of a tube mounted on holder and equipped with a loudspeaker at one end and a removable stopper at the other end. The loudspeaker is supplied with a function generator (not supplied) enabling you to vary the soundwave's frequency.
The amplitude of the sound signal is picked up by an electret-foil microphone, mounted on a mobile rod inside the tube. The displacement is carried out thanks to a turn button.
Recordings of the displacement and the received signal are made with a computer from any Computer-Assisted Experiment system. An oscilloscope can also be used to display the received signal.

Characteristics Specifications:

Three analog outputs:
- 5 V / + 5 V proportional to the displacement,
- 5 V / + 5 V proportional to the sound signal,
- 5 V / + 5 V proportional to the signal envelop.
Loudspeaker: 8 Ω / 0.25 W.
Distance micro/loudspeaker: adjustable from 0 to 500 mm.
Power supply: 12 V mains adapter, supplied. 4 mm safety sockets.
Dimensions: 700 x 100 x 96 mm.
