Abstract

The flush mounted pressure tap which is mounted in a pressure sensor and further installed in the cleaner subsystem of a Xerographic processor tends to become clogged with toner after about 200,000 copies. Consequently, the pressure sensor is rendered inoperative. Therefore, an adaptor for the flush mounted pressure tap is provided to resolve the problem. Testing indicates that the proposed reversed pitot tube pressure sensor tap is effective when using low to moderate amounts of toner within the air flow of the pressure sensor. After 2 million machine copies, reverse pitot tube pressure sensor taps are still working with no blockage to the pressure sensor tubing.

REVERSE PITOT TUBE PRESSURE SENSOR TAP(Cont'd)

The flush mounted pressure tap which is mounted in a pressure sensor and further installed in the cleaner subsystem of a Xerographic processor tends to become clogged with toner after about 200,000 copies. Consequently, the pressure sensor is rendered inoperative. Therefore, an adaptor for the flush mounted pressure tap is provided to resolve the problem. Testing indicates that the proposed reversed pitot tube pressure sensor tap is effective when using low to moderate amounts of toner within the air flow of the pressure sensor. After 2 million machine copies, reverse pitot tube pressure sensor taps are still working with no blockage to the pressure sensor tubing.

In the figure, a reverse pitot tube pressure sensor tap 22 is shown mounted to the interior of a pressure sensor tube 10. The pressure pitot tube pressure sensor tap 22 is a L-shaped piece of aluminum tubing of approximately 0.093 inches in diameter, which is fixed to the pressure sensor tube 10 by a nut 28. A 1/4 inch hose fitting 20 is attached to the reverse pitot tube pressure sensor tap 22 on the outside of the pressure sensor tube 10. On the inside of the pressure sensor tube 10,...
