B16M 4-20ma pressure sensor input

[mattorola7]

I'm trying to install a Wika A-10 Pressure Sensor/Transmitter 8-30VDC 4-20mA P# 13361091. This is the first time I've used a 4-20ma sensor. I've used other 0-5V and 0-10V sensors before with voltage dividers and have been successful.

Can you help me understand how the A1 and A2 Analog Inputs on the B16M work to convert the 4-20ma signal into a voltage and what I should use for the gain? ChatGPT is trying to explain it to me but it describes using a 250ohm shunt resistor. How do I know what internal shunt resistor(s) have been used to convert the signal to be readable by the internal ads1115 chip?

I will be using 12VDC to excite the pressure sensor which is rated for 8-30VDC. The Wika test report shows that the sensor should produce 4ma at 0 bar and 20ma at 2.5 bar (36.2595 PSI). Here is a snapshot of my YAML code for esphome so far:
