Re: RTD input with decimal places


In regards to the negative °C value, the temperature I had the PT100 probe exposed to was around -3C, and based upon the spec sheet for the probe I got it was still within applicable ranges. It only wrapped around into a large int when it was in the negative range. I don't think it was the probe ...

I have continued adjusting the Multiplier, Divisor, and Offset values to try and get values with more digits past the decimal place. In the screenshot below, I made these adjustments for °F. The output value of 69.62 °F appears valid based upon the ambient temperature of where the probe is, so I was ...

Re: RTD input with decimal places

Thanks for the fast response Dirk.

I still don't see where I am getting an additional decimal place of accuracy when using the printf command to divide by 100. That is moving the decimal place, as expected, rather than giving an additional digit of accuracy

As seen in my screenshot, the value of ...

RTD input with decimal places

Hello,

I am just getting started using RevPi, so I my familiarity with several of the menus and areas is limited at the moment. I was testing connecting a RTD P100 to the RTD1 input.

Thermocouple Input

I am looking to use RevPi hardware to replace existing hardware deployments that uses many thermocouples. I see that the current available expansion modules do not support thermocouple inputs. I do see RTDs, but I am looking to use thermcouples for my use case.

Seeing as getting 30 to 50 signal ...
