Hello everybody,
I am interested in making electric control decisions based on analog signals.
Many times I see machines which don't use digital signals but they are able to control electric behaviour based on analog signals.
For example I have a washing machine in my household. It has a heating part and it contains a termistor. The termistors current goes into a temperature selector and this is connected to the printed circuit board.
I know that termistor gives variable currents for variable temperatures, but I have a few questions related to other parts:
- I don't know what is the name of the electric part which "process" this signal (which is in the temperature selector)
- How it does it, and
- What is the output of it. Is this a standard dichotome signal, based on its position? For example it gives voltage if the selector is set to 30 and water is colder than 15 degree Celsius, and it does not give voltage, if the temperature is higher than mentioned?
