CURRENT SENSING RESISTOR HALL EFFECT BASED LINEAR CURRENT SENSOR Vcc+

Current Measuring Resistor  Measure the Current through the resistor inline to the destination.  Takes a direct measurement off the inline resistor. Hall Effect Sensor  Also measures current during the path to its destination.  Uses a pre-calibrated controller and sensor that measures magnetic field from the wire carrying the current.

CURRENT MEASURING RESISTOR HALL EFFECT SENSOR  Easy to install inline to voltage source.  Can be very cost efficient depending on amount of current and voltage being measured.  Very accurate  Not actually connected to voltage lines therefore less risk of damage.  Good for use with data acquisition systems

CURRENT MEASURING RESISTOR HALL EFFECT SENSOR  Can be damaged if wrong currents are applied because it is inline.  Can be less accurate.  Cost  Additional circuitry is needed as opposed to less for an inline resistor.

CategoryResistorHall effect Cost42 Safety35 Accuracy34 Total1011 The hall effect sensor scored higher due to safety because it is not directly connected into the power circuit and also it can be more accurate.
