Abstract
A Refrigerant Sensor is provided that provides within a common assembly pressure, temperature and superheat measurements and calculations with respect to a refrigerant material. The Refrigerant Sensor includes a pressure transducer for measuring the pressure of the refrigerant material and a temperature transducer for measuring the temperature of the refrigerant material. The pressure and temperature measurements are used by a microprocessor to calculate the superheat value of the refrigerant material. The microprocessor is within the common assembly. The Refrigerant Sensor can send and receive information from the network and also calibrate the pressure and temperature measurements.
