Sensors And Transducers #4993403

All sensors use electrical and electronic technology in sensing the assigned parameters and the output is electrical signals and analogue signals. However, the sensors defined under this category of electrical sensors and electronic sensors are those used for sensing electrical and electronic parameters such asvoltage, frequency, current etc. These are simpler in operation compared to most other sensors since these parameters are directly measurable in most cases without complication. In all other types of sensors, the assigned parameter is detected and converted into electrical signals.

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 carryingconductors 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 & Hall sensor for measuring current

Hall Effect sensor is a type of current sensor named after the inventor Edwin Hall. The major component is the hall device whichmeasures 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.
