Differential Temperature Controller

Published on : Tuesday 30-11--0001

Normal temperature controller acts on one single input and tries and maintain that temperature at a pre programmed constant level. A Differential Temperature Controller as the name suggests takes two temperature inputs and tries to maintain the difference between these two temperatures as constant.

This is widely used in today’s innovation Solar Energy Systems to provide maximum operating efficiency and flexibility. It automatically maintains the difference e.g., In case of self-powered solar box furnace or in case of a solar water collector. By automatically switching on a fan or a pump the temperatures can be equalized.
