Temperature Controller

  1. Jan 6, 2015 #1
    I am trying to replace a Temp. Controller that is no more produces anymore.
    What are the controller properties/settings/ that I have to pay attention to. in another word, what to select a temp controller for certain application?
    Thanks.

    What did you have before and what are you hooking it to?

    this was dumped on me today,
    the original controller was "ripped" for the application (industrial heating pad), long time ago. so there is no way to know which one goes where, meaning that no documentation what so ever of which wires go to the RTD, control, and power... is available.
    I am thinking about cross referencing the original controller with something that I will have in stock.
    to do this I wanted to know what should consider in a controller for it to go with my application.

    Thanks.

    Thanks of the Reply.

    you see just for the sake of analogy, if someone asks about what to look for in selecting an electric motor, I would answer RPM, current, Voltage,Frame, HP,

    I am looking for similar answer, but using Temp Controller instead of the electric motor. I know 2 so far that are the voltage and the Temp Sensing element (RTD, TC..) and wondering what the others are?

    Hope this makes sense

    Well, know the application helps to know in order to answer such a general question. But Okay. 4-20 ma loop?

    form, fit, function

    What do you know about the one that's no longer there ?

    First question is this an on off controller or a proportional device?
