Hall
effect Current Sensor gives isolated DC voltage out put
proportional to the AC or DC Current passing through. Sensors
with higher Current ratings are in the offing.
Normally
Current Sensors use resistive shunt or AC Current transformer.
These two methods have limitations and disadvantages.
Systems
new Current Sensor uses Hall effect to sense AC or DC Current.
The sensor is totally isolated from main Current and not
susceptible to external disturbances.
Current
Sensors has linearity over the range exceeding one and half
times. This gives an ability to withstand the overload without
damaging Current sensor. Further more, electric burden is
minimum as there is no resistive element in the series path
or no transformer burden as in the case of AC Current transformer.
Current
Sensors are not bulky and size does not increase with the
Current rating. They are compatible with existing conventional
measuring devices.
