Abstract
An automatic control for a refrigeration system for regulating the superheat of refrigerant in its gaseous phase existing in the system. The control includes a sensor arranged in thermal control with the system suction line that is divided by a diaphragm into two chambers. One chamber is exposed to suction gas and the other chamber contains a fluid that is essentially the same as the system refrigerant. Mounted on the diaphragm is a four leg strain gage bridge sensor that produces an electrical signal in response to the pressure differential between the chambers.
