Abstract
A super-heat detector of refrigerant gas comprises a semiconductor pressure sensor for detecting a pressure of the refrigerant gas in a refrigerating apparatus, a semiconductor temperature sensor for detecting a temperature of said refrigerant gas, and an operational controller which converts an output signal from said semiconductor pressure sensor to a value corresponding to a saturation temperature of said refrigerant gas pressure, and produces an output electrical signal corresponding to super-heat condition of said refrigerant gas by comparison between said corresponding value of the saturation temperature and said output from said semiconductor temperature sensor.
