Clamp ampermeter

Clamp meter is a useful tool that allows engineers to easily measure electrical current (amps). Simply place the fork around the current-carrying wire and measure the amount of current without the need to connect a probe and place it in a series of ammeters. In fact, the measurement theory of this device is based on the properties of the physical law that proves around There is a magnetic field current-carrying wire that is proportional to the amount of current or ampere of the wire. In practice, many of these devices use the Hall effect to measure the magnetic field around the wire that surrounds the crank or clamp, and the voltage corresponding to the field is sensed by the Hall effect semiconductor detector and currents into the device using a microprocessor. It becomes equivalent. Today, the use of clamp ammeters in the installation of instrumentation equipment, industrial automation, as well as electronic laboratories or electrical workshops, etc.
