C_R_PLC Posted May 31, 2018 Report Share Posted May 31, 2018 Title basically says the whole issue. I'm trying to get a usable reading from the sensor listed below, but it just seems to fluctuate between 2 and 3 volts even if nothing is plugged in. So my question is two-fold. Can I get a signal that is more precise than a whole number, and will that sensor even work with a PLC and if not is there anything I can get to interface the two?
