Thanks for your help, guys!
I believe, a sensor at the line potential is not a concern in this case. We are going to use something like GEFRAN 600. 230V will connect to a power supply input and a sensor will be connected to a temperature input.
The only reason for that transformer was...
>> Shouldn't the secondary be grounded somewhere?
Mmmm... It is not planed to be grounded. Should it be? The heatsink of the SSR will be connected to PE but it is different story, I believe.
>> Where is the temperature sensing element?
PID is a standard temperature controller in DIN format...
Hi,
We would like to develop a simple temperature controller to control a resistive electrical heater. A sketch of projected schematic is attached to this message.
Does that insulating transformer (T1) make a lot of sense? Or it is a waste of money?
The maximum current through a heater (H1)...
Hi!
We need to develop a heating plate for the food industry.
Conditions and Requirements:
- Humidity is close to 100%, condensation is visible;
- Temperature is 300 oC (actually cycling between 250 and 300 oC);
- The plate is suspended on nine rods (corners, center, and the middle of each...
