The FV-1500 calculates a rotational speed or speed by the time of pulse signal in a period from rotary encoder, and then converts this signal into analog signal to obtain 10V/full-scale. (Setting for full-scale is user selectable.)

Since the FV-1500 can output voltage or current with high-speed response of the time in a period of input signal+3.5μs, it enables to analyze the fluctuated speed with high-accuracy that occurs in startup.

The FV-1500 is equipped with deflection output function of center frequency at ±5V.

Measurement range: 0.2 Hz to 320 kHz
