FQ - Reed Frequency Meter


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.
