Hi guys,
i have a question regarding high temperature measurements: I want to measure the temperature of a reaction vessel at different points while it is inside an oven. I choose RTDs because they are rather small and cheap, but i could also use thermocouples.
Now i have a problem: How can i reliably connect the RTDs to wires? I can't solder them as the solder will just melt and twisting the wires together doesn't seem like a great idea either. Looking for RTDs with longer leads isn't an option either as they will be ~40cm deep inside the oven.
