This clip-on current transducer provides a quick and easy way to measure up to 25A of DC current running through a wire without cutting or disassembling anything in the circuit. It simply clips on to the wire and connects to a Phidgets VINT port or analog input. See the Connection & Compatibility tab for a list of devices you can use.

Note: The wire whose current you're measuring must have the power and ground separated out. If you measure both power and ground at the same time, the sensor will measure zero amps, because the current is the same in both wires and cancel each other out since they travel in opposite directions.

Formula

The formula for converting output voltage into DC Amps is: DC Amps = (V - 2.5) / 0.0625

Looping to Increase Resolution

If you need to measure less than 25A and want better resolution, you can loop the cable through the sensor a second time. The current value you get back from the sensor will be doubled, since it's measuring the same wire twice at the same time. You can divide this value by two, thus halving the maximum range from ±25A to ±12.5A, but effectively doubling the resolution of your measurement.

You can loop the cable through any number of times to repeat this process, although there will be diminishing returns as your resolution approaches the noise tolerance for the sensor. You could also cause problems with the measurement if the wire window is too full, if the wires shift around and push up on the clip.

Interface Boards and Hubs

This sensor can be read by any Phidget with an Analog Input or VINT Hub port. It will connect to either one using the included Phidget cable. VINT Hub ports can behave just like Analog Inputs, but have the added flexibility of being able to be used as digital inputs, digital outputs, or ports to communicate with VINT devices. For more information about VINT, see the VINT Primer.
