current shunt in our circuit is that heat would change the resistance so the measurements be as accurate with the rise of the current since the wouldn’t resistance would be a different value and this serve main goal wouldn’t project’s is to measure power with accuracy. This accuracy may not be achieved if Eddy Current Sensor was our choice current measuring component neither. In our power measuring strip design, out of many components more or less all of them will have magnetic fields since they are all electrical instruments. These components would interrupt the precision of the Eddy Current Sensor. On the other hand; Hall Effect Current sensor looks way more superior in measuring the circuit task because of its advantages such as: High speed and repeatability highly linearity, a very long life and isolation from another high voltage in the same system, so it be affected by the other components just like Eddy wouldn’t Current sensor would. Current transformers were a no go as well since they are really good for higher voltage measurements but their sizes are usually larger than the our design would allow and they be as beneficial as neither wouldn’t magneto resistive field sensor nor hall effect current sensor. The superiority of two sensors above compared to current transformer would be summarized as: for Hall effect current sensor; logic capability, highly linearity, non mechanical structure, resistance against heat, perfect to measure high currents for safety concerns, are insensitive to dust, vibration, humidity, cold and hot and well sealed structure. On the other hand for magneto resistive field sensor advantages over current transformer would be: good accuracy and high sensitivity, durability, fast response rate, decent size, can be used in harsh conditions and reasonable price. The two alternatives left, Magneto Resistive Field Sensor and Hall Effect current sensor were both good choices for our power measuring circuit design but our choice was towards Hall Effect Current Sensor. Besides the advantages they would bring to our power measuring circuit design reviewed in the above paragraph we had to go into detail to compare the two in order to make the best decision for our design. When two compared, we sow that Magneto resistive sensor had limited linear range, temperature drift and was sensitive to interfering magnetic fields from other components. Under these circumstances, our choice of going with Hall Effect current sensor was justified.
