Hello Shannon,
I am responding to your post from a year ago. I have been working on an interface that can take 12 V from a solar panel, run the 4-20mA sensors, convert the 12 V to 3.7 V to run Mayfly and sensor interface circuits. I have located one vendor (Global Water) that sells 4-20mA sensors at a low price but I would like to go through more options.
What do you recommend?
Also, What do you recommend for the “research-grade high-quality sensors”? Do you prefer a specific vendor?
Thank you very much.
