Hola a todos.!
Mi pregunta es: ¿Que bloque de NI DAQmx se podría utilizar para medir corriente alterna y posteriormente potencia eléctrica? actualmente cuento con sensores de efecto hall que envian 0-5 V y son capaces de medir de 0-100 A, ademas del modulo NI-9239 y un compactRio.
as this is an English forum you should write English messages - or use the Spanish forum…
My question is: What block of NI DAQmx could be used to measure alternating current and then electrical power? I currently have hall effect sensors that send 0-5 V and are capable of measuring 0-100 A, in addition to the NI-9239 module and a compactRio.
Usually the cRIO devices don't support DAQmx (only some new/recent types).
Usually you use either the ScanEngine or the FPGA inside the cRIO - both is explained in the example projects coming with LabVIEW(+RT+FPGA)…
To calculate power you also need to measure the voltage in parallel to current!
Sorry for write in spanish.. I have a recent versión of compact RIO (cRIO-9046), and I´ve done some programs like measure AC voltage with NI DAQmx and NI 9242. But now I want to measure AC Corrent, thats why im asking for what bock of NI DAQmx can use for this sensors because the output is 0- 5 VCD.

When the sensor outputs a voltage signal then you can still use the voltage reading…
(You may apply a scaling to the voltage reading to convert the values into the corresponding current values.)
