Summary

AN ACCURATE, INEXPENSIVE TEMPERATURE CONTROLLER UTILIZING THE PROPORTIONAL INTEGRAL DERIVATIVE FUNCTIONS HAS BEEN FABRICATED. THE CONTROLLER IS CAPABLE OF MAINTAINING THE SET TEMPERATURE CONSTANT WITHIN ABOUT 0.01 K IN A WIDE RANGE OF 73 TO 473 K (-200 TO 200 DEG C) WITH A RESOLUTION OF 0.1 K. IT UTILIZES AN INDIGENOUS PLATINUM RESISTANCE SENSOR EXCITED BY A STABLE CONSTANT CURRENT SOURCE. THE DIRECT CURRENT DETECTION TECHNIQUE MAKES THE CIRCUIT SIMPLE AND ENSURES LOW COST.
