ABSTRACT:
A heat transfer system includes a high side pressure sensor in the form of a temperature dependent resistance in heat exchange with the system working fluid to locally heat the fluid in response to a control signal. Control means are provided for applying the control signal to the resistance and detecting a minimum thermal resistance between the thermistor and the working fluid.
