Phidgets Inc. distributes the 3503_0 - i-Snail-VC-100 100Amp Current Sensor which connects to a number of USB data acquisition devices provided by Phidgets Inc. In this case it is the 1011_0 - PhidgetInterfaceKit 2/2/2 dongle. Phidgets Inc. provides the DLL for Labview and over 100 functions and Vi's for Labview. This makes Phidgets a low cost high result choice for current, power, voltage, distance, range, pressure, force, touch, motion, envioromental with a wide selection of data acquisition devices. The formula for calculating the current is: AC Amps (RMS) = SensorValue/10
