FQ96_und_FQD96-Zungenfrequnzmesser.jpg

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.
