Can a single TC be wired to operate 2 PID controllers ,or will it mess with the reading if another load is paralleled?
I'm going to figure out a reasonable way to use PIDs on a gas smelting pot. It will have 2 gas valves so I can have low, med, and high burner.
I think the low temp alarm will work for low-medium relay.
What I have in mind is splitting the output from a single regulator to two gas valves with needle valves to adjust the settings. I'm not sure about the low fire. Maybe a 3rd split will do for low/pilot mode.
Next hurdle is to find solenoid gas valves that are not ginormous with a built in differential. I need something simple like the water valves on a washing machine.
