High-speed F/V converter
FV-1500
The FV-1500 high-speed F/V converter is a highly responsive frequency (F)/voltage (V) converter that converts frequency signals proportional to rotational or moving speeds into voltage signals.
This system can handle the high-speed operation of motors used in hybrid and electric vehicles, as well as manufacturing lines in production plants. It can also measure startup characteristics, minute rotational fluctuations during steady-state rotation, and transient phenomena of flow velocity changes with high-speed response.
This function slows down and stops the rotation output (analog speed) when the input signal decelerates rapidly, such as in a rotating object, and the input is no longer than the previous pulse interval.
When the tracking function is ON:
The analog output becomes 0 if no signal is input after waiting for the set number of preceding signal pulse intervals (1.5 to 16).
When tracking function is OFF:
After the input signal becomes 0 (OFF), the analog output is held at the minimum measurement frequency (0.2 Hz) before becoming 0.
