Is it somehow built into your PID or is it some separate and remotely mounted analog device(s)? You realize, of course, that you have to be at least as old as we are to even know what an analog device is.
EOU, many PID controllers allow to use both, thermocouple or thermistor. I will use a K type thermocouple e.g. https://www.amazon.de/100mm-Spade-Thermo...uage=en_GB
What concerns analog devices, somewhere in the attic I have mercury thermometer which measures up to 650°C (1200°F).
The bricks were grooved and the elements were coiled. During the weekend I hope to post some images showing my progress.
