About  Current Sensors

Current sensors are meticulously engineered to identify and react to variations in the electrical current within a wire or circuit. These sensors come in various types, including current switch, flux gate, hall effect, current indicator, current sensor, magnetic modulator, magnetoresistive, and transformer with conditioning. They cover a wide range of current sensing capabilities, spanning from programmable sensors capable of measuring currents as low as 5mA to robust models designed for measuring currents as high as 2500A, whether it be AC or DC current. The diverse range of current sensors enables their application across numerous sectors, such as power systems, industrial equipment, renewable energy installations, and automotive systems. These sensors play a pivotal role in monitoring and controlling electrical currents, ensuring safety, efficiency, and optimal performance within various electrical and electronic systems.
