FA Digital Frequency Meter LED Display RPM Tachometer
Frequency meter is the instrument which receive the pulse signal from the sensor, and reappear the live mechanical equipment running speed by internal processing operations,thus to achieve the protection of field devices by its included output function. And it is widely applied on the instruments’ running status monitoring and operation speed controlling.
1) Pulse signal/high-voltage industrial frequency signal input.
2) Frequency/linespeed/tacho measuring is selectable.
3) One alarm relay output function.
4) Input signal is specially filtered, which improves anti-clutter ability.
For measuring frequency/tacho/linespeed/industrial frequency, high voltage industrial input signals are isolated while input/output to guarantee the reliable performance. Pulse signal input Models can realize linespeed/tacho/frequency 3 display function switchable using. And it is with large-size LED digital display which is more intuitive to view,it also featured wide measuring frequency range and one relay output function.
