Sensing Elements for Current Measurements
There are many choices of sensing elements to measure current to a load, and the choices of current sensing elements can be sorted by applications, as well as the magnitude of the current measured. No one sensor is the choice solution for all applications because for every positive about a sensing element, there is a drawback. This white paper provides an in-depth analysis of three different types of current sensing elements. It focuses on evaluating current measurements using a shunt resistor, a direct current resistance (DCR) sense circuit and a Hall Effect sensor.
