  • Temperature compensation control
    Patent number: 3995810
    Abstract: A temperature compensation system using forward biased pn semiconductor junctions as temperature sensing elements to compensate for the rate of heat loss or gain by controlling the temperature of a fluid heat exchange medium. A differential amplifier is driven by changes in the junction voltage drops and controls power to the heating element so as to maintain a controlled relation between the temperature being overcome and the temperature of the heat exchange medium.
