How to connect temperature (pressure) sensor with current output to Raspberry PI?

Question

Automation

Good afternoon, community!)
I don’t know how, but I chose the path of an engineer for myself and now I have to gnaw on granite and other hard rocks.
I solved a lot of technical problems on the Raspberry Pi and, oh naive, I began to believe that I understood something about it. But thanks to the head of the department, he quickly landed me. I set the task to connect a temperature sensor with a current output to the raspberry and read the temperature.
How to connect a temperature sensor to the GPIO is clear, writing software is also clear how. But how to work with the current output?
I rummaged through google, heard enough of Hindu English, fell into despair.
Please point your finger in which direction to look, except for changing your future profession)

Answer 1

Unlike digital current loops, which often involves simple optical isolators, when talking about the Analog industrial control method, the theoretical solution would be to convert the current to a voltage in a range suitable for an ADC chip using a resistor, and adding an external ( I2C or SPI (which could be optically isolated) ADC, see picture below) to the PI.
