RTD تھرمل ریزٹر درجہ حرارت کا پتہ لگانے کا سینسر کیا ہے؟?
An RTD (مزاحم درجہ حرارت کا پتہ لگانے والا) is a sensor whose resistance changes as its temperature changes. The resistance increases as the temperature of the sensor increases. The resistance vs temperature relationship is well known and is repeatable over time.
