Abstract
An oxygen leakage regulator tester to test for air leaks in O2 supply equipment, such as oxygen masks and hoses used by flight personnel. The tester uses electromechanical sensors and a central processing unit, coupled to digital displays for accurate readouts.
Claims8
An energy efficient, easy to read, portable digital gas leak detector for testing air leakage in oxygen supply equipment comprising:
- means for introducing pressurized gas into said equipment in fluid communication with said equipment;
- means for manually manipulating the pressure of the gas introduced into said equipment in fluid communication with said means for introducing pressurized gas;
- means for measuring said pressure and leakage of said introduced gas in said equipment in fluid communication with said means for introducing pressurized gas;
- and
- means for displaying said pressure and said leakage in electronic communication with said means for measuring said pressure and said leakage;
- said means for displaying said pressure and said leakage includes an LCD pressure display and an LCD flow display each in electronic communication with a central processing unit (CPU);
- a power supply in electronic communication with the CPU;
- and
- a pressure switch in electronic communication with the CPU, whereby the power supply is only engaged to the CPU at or above a predetermined gas pressure.
