As controls engineers delve into this field, one of their initial encounters with a control system is often with the PID controller, and this open source project delivers two of these general ...

The PID digital electronic controller can reach temperatures of up to 200 °C. An independent temperature safety circuit prevents delicate samples from overheating. This comprises two needle valves ...

After a few tries at fitting and finding the right placement for the thermocouple, he then reassembled the iron, and attached everything to an off-the-shelf industrial PID controller. Not one to ...
