Shunt measure current
Did you know?
WebA current shunt is a resistive element placed in the current signal path that uses the linear relationship between voltage and current in a resistor (V = RI) to measure current flow. The voltage measured across the shunt resistor indicates the current passing through the element. SSA current shunt uses series resistance to measure current. WebHello, I am trying to measure current through a relatively high power (~60a peaks) drill wirelessly. I had been doing so with a 0.1mohm shunt built into the battery and a dataq di-2008 however we now have needs to do that wirelessly, i should not need ad much resolution as the dataq, probably 10bit would work, but would prefer more.
