ABSTRACT:
A test system for air data sensors includes means for mounting the system components directly on the sensor and provides a self contained source of the necessary vacuum or positive pressure as needed for testing the sensor for function. The self contained test system includes manual pressure creating means that is self limiting to prevent excessive pressures being generated. In one form of the invention the entire assembly slips over and is supported on a sensor probe, and includes passageways and connections to provide the fluid pressures required to the sensing ports. In a second form, the self contained test system mounts on the sensor strut and has a pressure fitting that fits over the ends of a probe barrel to provide an adjacent coupling means for supplying the fluid pressures to the respective ports. The test system is a compact, easily mounted unit that is supported directly on the air data sensor being tested, and which has self contained fluid pressure sources for the necessary test. It is easy to use with minimal training of the operators, compact, and does not require any electrical power nor any other power supply.
