 three phase AC LED current meter

Description and meaning of model

Ammeter is a measuring current of the instrument. The main types of rotating coil type ammeter, turn iron ammeter, thermocouple ammeter and hot-wire ammeter. Ammeter inside a permanent magnet, the magnetic field generated between poles, there is a coil, the coil springs at each end of the spring in a magnetic field, a current meter connected to the respective terminal spring, between the coil spring and a connecting shaft, the shaft relative ammeter on the front end, there is a pointer. When a current is passed, the current along the spring shaft through a magnetic field, the magnetic induction current cut line, so that the role of the magnetic force of the coil deflected drive shaft, pointer deflection.
