The Vout at 0 A is supposed to be 2.5 V however my serial monitor reads 2.7028 or 2.707 and so on (not staying constant) But when I measure using multimeter ( by touching the Vout and ground pin on sensor) I get 2.51 V. Each magnetic measuring device comprises a magnetic circuit provided with at least two interleaf gaps and a magnetic field sensor arranged … Open-loop current sensor. You can find the code on: https://github.com/kshitijdadhekar/Current-Sensor I am new to electronics and cannot work out how to connect my three pieces together. Your "voltage output" sensor could however have zero and span instability if you read it directly with an Arduino. During the current sensing process, the current is measured by measuring the magnetic field. When utilizing a Linear Hall Effect sensor for current measurements, the sensor/concentrator is usually configured either in an open-loop or closed-loop configuration. If -60A of current is flowing (other direction) then Vout = Vref - 1.25*60/200 or about Vref-0.375V. Rated at 2000A, ratio 1:5000. Globetek has collaborated with LEM, the world’s leading manufacturer of voltage and current sensors, to bring hi-tech testing equipment to India. Lem Liaisons Electron Mec: current sensor.
