In the figure we have a trigger circuit using an SCS with a common incandescent lamp as load. The circuit is from a 1964 General Electric publication.
This circuit was found in a 1987 publication, but it can still be easily assembled today as the...
This circuit uses a common diode as sensor. The output goes from 0 to 10 V with the temperature change in...
This circuit, from an old publication, can also use modern transistors. Note that the unit is...
