INDOTECH ANALOG FREQUENCY METER

Indotech Analog Frequency Meter – Indotech Digital frequency meter is a general purpose instrument that displays the frequency of a periodic electrical signal to an accuracy of three decimal places. It counts the number events occurring within the oscillations during a given interval of time. As the preset period gets completed, the value in the counter display on the screen and the counter reset to zero. Various types of instruments are available which operates at a fixed or variable frequency. But if we operate any frequency meter at different frequencies than the specified range, it could carry out abnormally. For measuring low frequencies, we usually use deflection type meters. The deflection of the pointer on the scale shows the change in frequency. The deflection type instruments are of two types: one is electrically resonant circuits, and other is ratio meter.

TYPE OF METER: ANALOG FREQUENCY

There are two type Frequency Meter-

VIBRATING REED TYPE :

The element of these instruments consist of steel reeds which are in the field of an electromagnet. These reeds vibrate in resonance with the energizing A.C. Only the reed whose natural frequency corresponds with the frequency of the A.C. supply will vibrate at full amplitude indicating the correct frequency on the dial.

TRANSDUCER TYPE :

This basically consits of electronic circuit coupled with moving coil meter. Oscillator circuit gives the signal according to the frequency of supply which is indicated on the dial of the meter.
