Would anyone know how to convert a 4 wore sensor to 2 wire using resistors only? Or even how to read from a 4 wire from arduino. Because i didn’t see a device that captures a 4 wire signal.
can you share the sensor part number?
Really old sensor from like 1998 part number is dfr-24. Its a doppler flow meter. No Data sheets are available because its so old. I had to figure out how to wire it by looking at the circuit board.
I have 2 connections for power
And 2 more for signal whis has a +14v and -14v
If i ground the -24v and -14 i get an open loop on multimeter.
I pulled the component off an old SLC
sorry no idea how this will work.
