  • looking for a DC controller for kettle burner

    We have a midco variable blast burner http://www.midcointernational.com/pr...000/re4400htd/ and engineer says we need to source a " 2-10 vdc signal, including the power supply. A model train transformer would work."

    Would be nice to be waterproof -- have searched Mcmaster and Grainger and come up empty so far. Any suggestions?

    A standard PID controller should suffice. Just make sure it has the appropriate voltage output. I'm planning on using the same midco and am going this route.

      If you're handy, you can build a simple variable voltage divider, that can give you 2-10v, or get a adjustable voltage regulator.

        Which specific device did you end up going with, and how's it going? Thanks!

          I've had good luck with the RedLion PXU controllers. They have a 0-10V output model that you could limit the minimum output to 2V so it should work. Most of the PXU units accept a variety of inputs (RTD, thermocouple, voltage, current). Prices are between $100-120 or so.

          Overview: Red Lion's PXU line of PID controllers is the perfect solution for your basic control requirements. The PXU’s capabilities cover applications requiring simple on/off control all the way to full PID control. Featuring one of the industry’s largest displays, the PXU is easy to read from a distance. Available in various sizes, 1/16, 1/8 and 1/4 DIN and packaged in a space saving design, the PXU can be installed into enclosures with a reduced depth to save space and money. Display: The PXU offers a dual line display with four digits on each line.

            Inexpensive PID's can be found here: http://www.auberins.com/index.php?ma...=index&cPath=1
            I went with a non controllable midco for the short term, so haven't got a specific model to recommend. Just make sure it has the appropriate outputs and you're good to go.
