synchronoscope - Vibrating Reed Frequency Meter - frekvensmåler

Merkelig instrument som jeg ikke vet hva heter på norsk. På engelsk heter det Vibrating Reed Frequency Meter og ChatGPT beskriver det slik:

The instrument is known as a synchronoscope or, more specifically, a vibrating reed frequency meter.

Principle: This instrument operates by having multiple reeds (or "tuned fingers") that vibrate at specific frequencies. When the grid frequency matches the natural frequency of a reed, it resonates and visibly vibrates, allowing you to read the exact grid frequency. Each reed is tuned to a particular frequency, typically in 0.5 Hz increments, providing a clear indication of the frequency.

These meters are commonly used in electrical systems to monitor the grid frequency and are valued for their simplicity and accuracy in showing small frequency deviations.

Det kobles til stikkontakt (230V) og viser nettfrekvensen helt nøyaktig.
