Phidgets Current Sensor with Labview

[hacklord]

Developed by Robert Emin

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
