Non-intrusive "Clamp-On" current sensor
“Clamp-on” or “Cable clamp” Current Sensors are sensors that are used for measuring AC or DC currents. They are particularly useful for measuring currents flowing in a cable wire in a non-intrusive way.
The “clamp-on” current sensors are particularly useful for easy and safe installation. They are installed straightforwardly onto a wire going into the electrical load without the need to do any high voltage electrical work. The current sensor consists of a Melexis Hall Sensor (MLX91208) and a patented ferromagnetic structure packaged in a robust plastic housing.
This non-invasive current sensor (also known as a “split core” or “cable-clamp” ) can be clamped around the supply line of any electrical load to tell you how much current is passing through it. It monitors the magnetic field around a current-carrying conductor and outputs a voltage proportional to the current.
The clamp-on current sensors measure loads from +/-5 Amps to +/-230 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.
