This example shows how to measure the rotational speed of a compressor built into an air conditioner and similar equipments. The FT-7200, used in combination with accelerometer, enables to measure the rotational speed of compressor to perform frequency analysis through FFT calculation even if the rotational shaft is not come out.

Analog signal output and sensor signal monitor output are provided as standard function. Analog signal output can be used for recording the fluctuation of rotational speed by pen-recorder and so on, and sensor signal monitor output can be used in order to check the shape of signal waveform.
