Ampere Meter Price, Digital Ammeter, ac / dc Panel Meter

Product Description

An ammeter is an instrument used to measure the current in AC and DC circuits. In the circuit diagram, the symbol of the ammeter is circle A. The current value is in “A” as the standard unit. It is made according to the action of the current-carrying conductor in the magnetic field. There is a permanent magnet inside, which generates a magnetic field between the poles. There is a coil in the magnetic field. There is a hairspring spring at both ends of the coil, and each spring is connected to a terminal of the ammeter. , the spring and the coil are connected by a rotating shaft, and there is a pointer at the front end of the rotating shaft relative to the ammeter. When a current flows, the current passes through the magnetic field along the spring and the rotating shaft, and the current cuts the magnetic induction line. Therefore, under the action of the magnetic field force, the coil is deflected, which drives the rotating shaft and the pointer to deflect. Since the magnitude of the magnetic field force increases with the increase of the current, the magnitude of the current can be observed through the deflection of the pointer, which is called a magnetoelectric ammeter.

Applications: Ammeters are used on induction melting furnaces.
