Working with 4-20mA sensor www.omega.co.uk/pptst/PXM4200-I.html
with Transmitter https://store.ncd.io/product/1-channel-4-20ma-current-loop-transmitter-i2c-mini-module interface Raspberry Pi.
The major issue i have been facing that sensor is giving the reverse value. For example, at 4mA it is giving 5v (Max) and at 20mA it is giving 0v. i have check all my connections as well as code, but still not able to find out the cause.
Your Help will be much appreciated
Sounds just like a 4-20 ma. Current sink. Your load would go from the output to the positive supply terminal.
The absolute voltage across the load would then make sense.
You have choosen a 4-20mA transmitter that outputs 4-20mA over a range of DAC counts from 670 to 3460.
What you need is their 4-20mA receiver that will take a 4-20mA input and provide a DAC count.
