China 2020 Best Selling Ammeter Z026 for Glass Machine

AMMETER is based on the conduction in the magnetic field by the role of magnetic force and made. There is a magnet inside the ammeter which generates a magnetic field in the magnetic field. In the magnetic field there is a coil with a gossamer spring at each end. The spring is connected to a terminal of the ammeter. There is a pointer relative to the front end of the ammeter on the rotating shaft, and the pointer deflects. So the amount of current can be observed by the deflection of the pointer.
