The FV-1400 High-Speed F/V Converter is a high responding frequency-to-voltage (current) converter up to 120kHz that converts a frequency signal in proportional to rotational speed, general speed, etc. into analog voltage and current values for each period.

The FV-1400 High-Speed F/V Converter can measure and record a change in rotational speed in full-scale mode, rotational fluctuation in deflection output mode with high-accuracy. Easy to setup the range of frequency and rotational speed using digital switch, moreover, measurement value and setup menus are highly legible with the use of a fluorescent character display tube. Besides DC power input (12`42VDC) is convenient for in vehicle use.

It best suits measurement and record of 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.

 

Features

  • Maximum input frequency to 120kHz

  • With a very high speed, available to convert frequency to voltage every one period of a signal.

  • CAL signal output (ZERO/FULL).

  • DC power input (12 to 42VDC) is convenient for in-vehicle use.

  • Frequency/Rotation speed display is selectable.

  • Easy to recognize measured value and setting menu, using a fluorescent character display tube.

  • Digital switch makes it easy to set frequency/rotation speed.

  • Possible to stack upward(Designed for vertical stacking).

 

Main Applications

  • Measuring motor startup characteristics

  • Measuring the rotational performance of rotating equipment

  • Measuring the rotational fluctuation of engines and motors

  • Rotational performance test with an over load

CAUTION !
EThe total accuracy of current output is a sum of the deflection output accuracy and the full-scale accuracy including current output error in the table.

 

Example current calculation

Conditions: Input signal format DC, center frequency 50 kHz, scale 5%

Total current accuracy = Deflection output accuracy + Full-scale current accuracy = 2%+0.7% = 2.7%
