The standard you probably want is IO-Link, or close to it.
It was meant to bring a bit of smarts to the standard 3-wire sensors and basic actuation pins, with 100% backwards compatibility.
So you have a standard analog temperature sensor that outputs 4-20ma on its pins. With IO-Link, it still does that, but if you hook it up to an io-link master, you can just read the temperature directly in C/F on the same pins.
Or adjust the calibration. Or …
It's not a perfect match, mind you, but i think it's pretty close.
