As a bit of a project I'm building a simple control system to control my new 3 vessel RIMs system. It consists of three heating elements but I only have the power supply for two which isn't an issue as I shouldn't have to run all three elements at the same time. So I'm running two PID channels, one for the RIMS tube and the other for the HLT and Kettle elements with a switch to switch between the two. This is fine for switching the supply to the elements from the PID, but I also need to switch the thermocouples. I could just pull the thermocouple out of the thermowell of one and into the other as required, but I know it would be only a matter of time till I forgot to do that so ideally want it switched via the same switch. They are K-Type thermocouples but not sure if you can just simply connect thermocouples through a switch? Anyone have experience of a similar setup? Ta.
