Re: Current Measurement
Shameless plug for my workplace.
You need to use something called a shunt for accurate current measurement: http://bluesea.com/category/6/24/pro...e/overview/202 pn9230 Analog Meter Shunt 100A/50mV This means that at 100A there is a 50mv difference in voltage at the sense leads. Amplify this, and run it to an Analog port on the cRIO. Here is an application note that will explain it all for you: http://www.maxim-ic.com/appnotes.cfm/an_pk/746/ |
