High-response
Frequency-to-Voltage Converter
FV-1300 |
|
|
 |
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. |
