A compact, handheld device employing the FFT calculation method.
You can select the optimal algorithm from five different measurement modes.
Equipped with a tracking measurement algorithm capable of responding to rapid changes in rotational speed, such as startup and shutdown, as well as acceleration and deceleration.
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
The FT-7200 Advanced Handy Tachometer is a user-friendly, highly functional, compact, handheld, high-performance Digital Tachometer. It measures rotational speed using FFT (Fast Fourier Transform) calculations from various signals such as noise, vibration, and magnetic flux changes generated by motors, engines, and other rotating machinery. Even with complex waveform signals from sound level meters and vibration sensors, it can reliably extract frequency components corresponding to rotational speed using its five measurement modes.
The FT-7200 allows for easy measurement of rotational speeds, even for motors and other components already integrated into products where the rotating shaft is hidden and difficult to measure using conventional methods, by detecting sound and vibration. There is no longer a need to attach reflective marks to the object being measured or to perform special modifications to the rotating shaft, as was previously required. Furthermore, thanks to its new algorithm, the FT-7200 calculates and displays rotational speed with high responsiveness, even in the face of rapid changes in rotational speed such as motor start-up/fall-down and sudden acceleration/deceleration of engine speeds, which were previously difficult to track. Its battery-powered, handheld design makes it convenient to carry to measurement sites and allows for easy measurement.
A wide range of compatible sensors (sold separately) are available to suit your needs, including microphones and sound level meters for sound detection, acceleration detectors and engine vibration detectors for vibration detection, ignition pulse detectors for magnetic flux detection, and the FT-0801 cigarette lighter socket sensor (released simultaneously) which detects ignition noise from the voltage output from the car's power outlet (cigarette lighter socket).
