Compact, handheld type employing FFT calculation method
Even if the axis of rotation is hidden, the rotation speed can be calculated and displayed from sound and vibration.
It is possible to measure the rotation of even the thin rotating shafts of small (micro) motors and the blades of fans without contact.
We offer a diverse lineup of sensors to cover a wide range of rotation measurement applications.
Includes analog output function and averaging function.
Backlit LCD, large numerical display
Various types of rotating parts are used in automobiles, office automation equipment, home appliances, and other products. While it has been necessary to constantly monitor the rotational speed of these parts in the manufacturing facilities of such equipment, until now, it was required to install multiple different tachometers for each type of rotating part.
The FT-7100 handy FFT tachometer is a new type of tachometer that measures rotational speed using FFT (Fast Fourier Transform) calculations from various input signals such as sound, vibration, or magnetic flux changes generated by motors and various rotating machines. Even from complex waveform signals from sound level meters and vibration sensors, it reliably extracts the frequency components corresponding to rotational speed and calculates and displays the rotational speed. Moreover, it is a handy type that is convenient to carry to the field. It can easily measure the rotational speed of motors and other components that are already incorporated into products, where the rotating shaft is hidden and measurement was difficult with conventional methods. There is no need to attach reflective marks to the object to be measured or to perform special processing on the rotating shaft, as was done in the past. Furthermore, it can track and calculate and display rapid changes in rotational speed, such as motor start-up/fall-down, and rapid acceleration/deceleration of engine speed, which was difficult to do before.
