Frequency-to-Voltage Converter


Photo (FV-1300 High-response F/V Converter)

The FV-1300 F/V converter has an excellent response rate, converting each period of frequency signals (measured in either rpm or velocity) into voltage or current signals at a very high speed.
By employing a digital signal processor (DSP) in the computation section, we have achieved high accuracy and multi-functional capabilities at a low price, resulting in a good cost/performance ratio.
The FV-1300 can measure and record the transient phenomena that occur in the rotational speed, flow rate, frequency fluctuation, and so on, such as the rotation startup characteristics of engines and motors and the minute rotational variations during stable rotation.



  • Fast response of 7.6μs, most suitable for measuring startup characteristics

  • High-resolution output by 16-bit D/A converter

  • Flexible frequency range that can be set on a 1 Hz basis

  • Deviation output function that enables rotational variation to be measured with high sensitivity

  • Moving average function

  • Isolated inputs that withstand common mode noises

  • Input frequency display function


Major Applications

  • Measuring motor startup characteristics

  • Measuring the rotational performance of rotating equipment

  • Measuring the rotational variation of engines and motors

  • Rotational performance test with an excessive load
