Description

Features

  • For measurement frequencies of AC supply
  • Range from 45 Hz to 65 Hz
  • Good read-out survey on larger distance
  • Minimum effect of temperature
  • Low power consumption

Application

The vibrating-reed frequency meter is one of the simplest devices for indicating the frequency of an AC source. They are usually in-circuit meters, used on power panels to monitor the frequency of AC. Two-systems reed frequency meters with two rows of reeds and two separate AC voltages can be used to synchronise two generators in parallel.
