The calorimeter is a device that measures the heat output of the material contained in the calorimeter cell. A special class of calorimeter is used for the measurement of nuclear materials and is referred to as a twin bridge resistance calorimeter. The measuring cell is contained in some type water bath at constant temperature. The associated electronics are used to convert the heat output signal into watts of power. The measuring cell is constructed of four resistance arms connected in a Wheatstone bridge configuration. Two of the arms are maintained at a constant reference temperature by a controlled circulating bath which acts as an infinite heat sink. The other two arms are wound around the sample chamber so they are physically between the sample and the heat sink. Connecting the four arms in a Wheatstone bridge configuration produces double the output voltage.
