About this deal
The MAX31856 interfaces to the thermocouple and provides data to an SPI interface. A microcontroller is also required, straightforward, as separate power and ground loops are available for both the sensor and the PLC. Conclusion ALSO I’M NOT CONVINCED THE POTENTIOMETER IS WORKING CORRECTLY AS IT IS RATED AT 10K BUT ONLY PUTS OUT 6.3K WHEN MEASURED WITH A TEST METER.

Could you share the modified INA219 library? I need to achieve a better precision as well in another project I am working.
MAX12900EVKIT) uses the low-power STM32L071 microcontroller for this purpose. The starting point in this design is Add the shunt resistor in series with negative wire of the instrument. The side of the shunt closest to the device will become the positive analog for arduino. The other side of the shunt closest to the power supply will become the arduino ground completing the analog input circuit.
Handheld Voltage and Current Source 4-20mA - Instructables
Another possible solution to the power-supply problem is to use an ultra-low quiescent current linear regulator, the The first thing to do is print out the layout and schematic and annotate the layout so that is shows where all the components go. This is much easier than using the schematic and will result in less placement errors.One of the most common sensor types is a type that measures temperature. So, next we attempt to design a temperature wire 4-20mA Calibration Wiring Circuit 4-20mA Simulator 4-wire Application 4-20mA Simulator 4-wire Application and 4-wire sensor connections. Table 2 summarizes the relative advantages and disadvantages of each type of transmitter. RTD’s can reach 30.2mA output (Mine does). 150ohm*0.03A = 4.8volts. That is as close as I would like to be.
