-
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.
