Analog Current to Voltage Converter(for 4~20mA Application) connection (SEN0262)

Hi

I'm trying to read an IR temp sensor with 4-20ma current loop output with a microcontroller. I don't have access to the analog inputs so I found the SEN0262 + DFR0553 as a good solution.
I have a question about the current to voltage converter.
The way it is connected to the sensor in the wiki differs to the information from the sensor's datasheet so I was wondering if it will still work.

Is it possible to connect the current input to the 4-20 loop and the current output to ground as in the picture below?

This is feasible. SEN0262 is similar to an ammeter, just connect it in series in the circuit.
