No sensor installation processing or reflective markings required.
Easily measure rotation from sound and vibration.
Equipped with a tracking measurement algorithm that can respond to changes in rotational speed and acceleration/deceleration.
In addition to the analog output function for rotational speed, a pulse output function corresponding to the rotational speed has been added.
RS-232C communication functionality is included as standard.
The addition of Ethernet communication functionality (optional) enables control via LAN.
The FT-2500 Advanced Tachometer measures rotational speed from noise, vibration, or magnetic flux changes generated by motors and various rotating machinery. By employing FFT (Fast Fourier Transform) in its calculation unit, it extracts frequency components corresponding to rotational speed even from complex waveform signals from sound level meters and vibration sensors, and calculates and displays the rotational speed. It can easily measure the rotational speed of motors and other components already incorporated into products, where the rotating shaft is hidden and measurement was difficult with conventional methods. There is no longer a need to attach reflective marks to the object being measured or to perform special processing on the rotating shaft, as was previously required. With the incorporation of a new algorithm, the FT-2500 can measure not only the steady rotation of motors and engines, but also acceleration and deceleration rotations with good tracking accuracy.
