Product Description

The ammeter is made based on the magnetic field force exerted by the current-carrying conductor in the magnetic field. There is a permanent magnet inside the ammeter, which generates a magnetic field between the poles. There is a coil in the magnetic field. There is a hairspring spring at each end of the coil. Each spring is connected to a terminal of the ammeter. A rotating shaft is connected between the spring and the coil. The rotating shafts are opposite to each other. On the front end of the ammeter, there is a pointer. The pointer deflects. Since the magnitude of the magnetic field force increases as the current increases, the magnitude of the current can be observed through the deflection of the pointer. This is called a magnetoelectric ammeter, which is the kind we usually use in the laboratory. Generally, currents of the order of microamps or milliamperes can be directly measured. To measure larger currents, the ammeter should have a parallel resistor (also called a shunt). Mainly adopts the measuring mechanism of magnetoelectric electric meter. The resistance value of the shunt should be such that when the full-scale current passes through, the ammeter deflects fully, that is, the ammeter indication reaches the maximum. For currents of several amps, a special shunt can be set up in the ammeter. For currents above a few amps, an external shunt is used. The resistance value of a large current shunt is very small. In order to avoid errors caused by lead resistance and contact resistance added to the shunt, the shunt should be made into a four-terminal form, that is, it has two current terminals and two voltage terminals. For example, when using an external shunt and millivolt meter to measure a large current of 200A, if the standardized range of the millivolt meter used is 45mV (or 75mV), then the resistance value of the shunt is 0.045/200=0.000225Ω (or 0.075/200=0.000375Ω). If a ring-shaped (or stepped) shunt is used, a multi-range ammeter can be made.
