Electrical Current Sensor

For measuring current in low voltage AC and DC circuits, current sensors are used. The current rating of up to 250 A can be measured using these sensors. Split core type sensors are easy to be mounted across current carrying conductors by opening the core of the sensor. Similar to voltage sensors, there are also available with 4-20 mA output and digital outputs suitable for automation purposes.
For the selection of current sensors, you have to determine the current to be measured, the direction of current (unidirectional or bidirectional), output signals required etc.

Hall Effect sensor is a type of current sensor named after the inventor Edwin Hall. The major component is the hall device which measures the current utilising the Hall Effect and produce proportional output signals. The basic principle is the measurement of magnetic flux density which is in proportion to the associated current. Hall Effect sensors or hall sensors are also used as switching circuits, in which the output will be a switching circuit determined based on the input parameters. Hall effect sensors are simply known as hall sensors also.
