This non-invasive current sensor (also known as a “split core current transformer”) can be clamped around the supply line of an electrical load to tell you how much current is passing through it. It does this by acting as an inductor and responding to the magnetic field around a current-carrying conductor. By reading the amount of current being produced by the coil, you can calculate how much current is passing through the conductor.
This particular current sensor will measure a load up to 30 Amps which makes it great for building your own energy monitor to keep your power usage down, or even building an over-current protection device for an AC load. This sensor does not have a load resistor built in, so in most cases it will be necessary to place a resistor across the output to convert the coil’s induced current to a very small measurable voltage.

這種非侵入性的電流傳感器（也被稱為“分裂鐵心電流互感器”）可以圍繞一個電負載的供給線被夾緊告訴你多少電流通過它。它通過作為一個電感器和響應於磁場繞載流導體這一點。通過讀取由線圈產生的電流的存在的量，就可以計算出多少電流通過導體。
這種特殊的電流傳感器將測量的負載高達30安，使得它非常適合建立自己的能源監測，讓您的用電量下降，甚至建立一個過電流保護裝置的交流負載。該傳感器沒有內置在一個負載電阻器，因此，在大多數情況下，這將是必要的，以將一個電阻在輸出轉換的線圈的感應電流到非常小的可測量的電壓。
