Was hoping for at least some replies…

To be complete, this is the code I use:

/*

ReadAnalogVoltage

Reads an analog input on pin 0, converts it to voltage, and prints the result to the Serial Monitor.

Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu).

Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.

This example code is in the public domain.

// the setup routine runs once when you press reset:

void setup() {

// initialize serial communication at 9600 bits per second:

Serial.begin(9600);

}

// the loop routine runs over and over again forever:

void loop() {

// read the input on analog pin 0:

int sensorValue = analogRead(A0);

// print out the value you read:

Serial.println(sensorValue);

}

Apologies, not sure where these “font” HTML codes came from, I didn’t put them there…

Thanks for the tips, I will certainly give it a go!

Hi Friedl,

Thank you for your reply.

I must admit that I did see minimum supply voltage @8v for the sensor. I ignored that for convenience sake. Because the readings did change with the temperature I asumed the sensor still worked, furthermore @100C the voltage would have been well over 8v, but the reading did not change significantly.

That being said, you might be right this is an issue. I do however not see how using the Maxi Automation in 0-10v with 500ohm resistor would help my situation, am I missing something?

The more I think about it I start to see this sensor simply isn’t suited for 4-20mA to 0-10v conversion. Because of it’s two wire construction, the power supply and signal share the same wires.

Perhaps I should try again with a 3 wire sensor, where power and signal are separated.
