Self-Contained Intelligent Sensor-Actuator for Temperature Control
Keyword(s):
Some electrically conductive polymer composites show positive temperature coefficient behavior during one temperature range followed by negative temperature coefficient behavior during the next range. The change normally occurs at a well-defined switching temperature. This paper proposes to use this phenomenon to develop an intelligent sensor-actuator device suited for temperature control applications. Two conductive composites were prepared and their switching temperatures were determined experimentally. Then a heated tube was made, with one of these composites as the heating element, and tested for the sensing-actuation control action. The results are very promising for future development of a wide range of such devices.
