Survey & Experiment:How to control tempreture.
Survey
Tempreture control should be needed to melt plastic bottles. But I had no knowledge about tempreture control at all. So, I started to survey about how to control tempreture. As the result of survey, following parts are needed.
- thermocouple
- band-heater or heat-cartridge
- controller(buy or make)
- AC power cable
- crimping terminal
- Inlet, Outlet
- SSR
Experiment
First, I bought the PID tempreture controller, because I had to understand usual method.
Connected the parts as described in the manual, it was able to controll tempreture of heat-band easily by measuring the tempreture with the thermocouple.
By using SSR, it is possible to switch ON / OFF of the heater with a small voltage. I understood that if I make something like a PID tempreture controller, I can control the temperature!
