What is thermal voltage (or the Seebeck effect)?
The effect, named after Thomas Johann Seebeck, describes the fact that an electric voltage exists when two different metallic conductors are connected at two different points, if there is a temperature difference between the connected and the open ...
moreWhat is the hysteresis?
Two-point control switches the output on or off depending on the deviation form the set point. This means that the output can frequently change with the smallest temperature changes. This can shorten the service life of the output relay and it can ...
