Using 4-20ma Sensor on NI WSN-3202

[jgottschling]

I have a vibration switch http://ifmefector.com/ifmus/web/dsfs!VKV021.html that I am trying to get to work in my wireless sensor network. NI only offers a voltage input node (NI WSN-3202), but the sensor is only available in 4-20ma output. The analog output is only 1 wire.

Is there a way to convert that signal to use voltage and have the WSN read it accordingly?

Thanks,

Josh

Put a precision resistor in the loop and read the voltage across the resistor.  For a 5VDC voltage input, use a 250 ohm resistor.
