ABSTRACT:
An electronic pressure gauge including a housing, a fluid pressure converter for converting the pressure of the test fluid into a voltage, an electronic low pressure point setting device for setting the desired low pressure point, an electronic high pressure point setting device for setting the desired high pressure point, an electronic low pressure point comparator for comparing the set low pressure point with the voltage of the fluid converter, an electronic high pressure point comparator for comparing the voltage of the fluid converter with the set high pressure point, and a control signal output device adapted to provide different output signals subject to the comparison result of the electronic low pressure point comparator and the electronic high pressure point comparator.
