Galvanometer Details

Galvanometer aik ammeter ki type hai. Galvanometer aik aisa instrument hai jo Electric Current ko detect aur measure karne ke liye istemal hota hai. Ye analog electromechanical transducer hai jo rotary deflection limited arc ke zariye aur electric current ko iski coil ke zariye response deta hai. Term ko wasee kiya gaya aur is mein recording, positioning aur servomechanism equipment ke liye same mechanism shamil hai.

Operation


Sab sey zyada istemal analog measuring instrument ke taur par hota hai jise aksar meter kaha jata hai. Ye Direct Current ko electric circuit ke zariye measure karne ke liye istemal hota hai. D'Arsonval/Weston jo form aaj kal use hoti hai usay aik chotay pivoting wire ki coil ke sath permanent magnet field mein construct kiya jata hai. Coil aik bareek pointer se attach hoti hai jo calibrated scale ko cross karti hai. Aik choti c torsion spring coil aur pointer ko Zero position par le jati hai. Jab direct current DC coil mein sey guzarti hai coil aik magnetic field ko generate karti hai. Ye field permanent magnet ke khilaf harkat karti hai.
Coil twist karti hai aur spring ke khilaf harkati hai aur phir pointer harkat karta hai. Scale par hand points electric current ko indicate karte hain. Pole pieces ka careful design magnetic field uniform hota hai isliye pointer ka angle current ke proportional hota hai. Aik kaaramad meter aam taur par mechanical resonance moving coil aur pointer jiski wajah sey pointer apni position par oscillation ke baghair jaldi settle ho jati hai.
