Mister rbt, is this a process scheme you're refering to? If I understood correctly process variable you're trying to control is temperature of water that is entering from the left on process scheme(A-B). Water that flows through pipes inside tank receive heat from the tank and in that way it rises its temperature. You have a solenoid valve on hot water supply inlet to the tank and you want to place there PT100 to use it as DISV input to PID block? AttachmentProcess Scheme.pdf (666 Downloads) |

Hello mister Pandiani, your attachment is almost right but the PT100 to messure the temp is not on produkt temp but on the outlet of the warm water. (see attachment) On the inlet we want to place an extra PT100 for feedforward control. But i don't exactly know what the functionis on CONT_S and if i can use this for that function. the product we want to heat is not water but fertilizer. Thats heated in the pipes by the warm water. greets Richard Attachmentantwoord.pdf (488 Downloads) |
