High-speed F/V Converter
FV-1500
FV-1500 High-speed F/V Converter is a frequency-to-voltage
(current) converter that converts frequency signal
proportional to rotation speed, moving speed, etc. into
voltage signal.
The FV-1500 is designed to accommodate the needs of
high speed rotation measurement including rotating
motors used in HV/EHV production lines etc. It also
contributes to measure rising characteristics, very
small fluctuation in steady rotation, and transient
phenomena of flow speed with fast response.
Features
- Wide frequency range : 0.2 Hz to 320 kHz
- High-speed response : 1 cycle + 3.5 µs
- Rapid deceleration follow-up function enables practical signal output even when the frequency brings about a sharp drop.
- Automatic center frequency follow-up function can close up transient fluctuation component (option).
- Provided forward/reverse output by rotation direction recognition using two-phase signal input.
- Comparator output useful for alarm system(option)
Typical applications
Rising characteristics of motor
Rotation performance of rotating devices
Rotation fluctuation measurement of engines or motors
Rotation performance test by applying excessive load
What is Rapid deceleration follow-up function (Estimating calculation function) ?
Output signal (speed analog) results in gradual reduction to stop when succeeding input signal of rotating device is suddenly decreased. The pulse interval is calculated every signal input. If no-signal period lasts longer than the previous pulse interval, this function enables the rotation output to be in gradual decline.
Follow-up function
ON
Analog output will be 0 when the no-signal
period lasts longer than 1.5 to 16 times of the last signal
pulse interval.
Follow-up function
OFF
Analog output will be 0 after that the
minimum measurement frequency (0.2 Hz) is retained from the
time input signal is 0 (OFF) for a while.
