Abstract
Control systems and calorimeters using them are provided. In certain examples, a calorimeter comprising a thin film sample sensor, a thin film reference sensor, a first controller configured to receive a temperature signal from only the reference sensor and to generate a first control signal, based on the received temperature signal, to provide average power to the sample sensor and to the reference sensor, and a second controller configured to receive temperature signals from both the sample sensor and the reference sensor and to generate a second control signal, based on the temperature signals received from both the sample sensor and the reference sensor, to provide differential power to only the sample sensor is described. Methods using the control systems and calorimeters are also described.
