      Hi all,

      I've been reading all possible documentation but it is still not clear what the correct and best/easiest way is to connect a Pt1000 probe to my NeuronL503 controlling it with Mervis.

      • Pt1000: Datasheet

      I've tried different things, but it never comes close to either the resistance value or temperature.

      Any tips/ examples?

      Thank you.

      Kind regards,
      Olivier

        Hello @OlivierP

        the first thing is to configure the AI to measure resistance as described on https://kb.unipi.technology/en:sw:01-mervis:analog-inputs-hidden

        Once that is done go to the same Properties Panel of the AI and choose transformation Lib.Core.V1_0.ResistanceToTemperature and then proper Kind of the transformation (used sensor).

        More on that in the built-in Help of Mervis IDE acessible in the upper menu Help or by pressing F1 and search for "Variable transformation, configuration of analogue inputs"

          Hi @tomas_hora ,

          Thanks, I was able to get it up and running. It is working nicely together with the PI controller to controller the compressor speed of a small cooling set-up for an indoor farm testing unit.
