ABSTRACT:
The invention relates to an oxygen sensor which measures the concentration of oxygen based upon ultrasonic sound waves traveling through a binary gas. The measured sound-wave delay through the gases determines the concentration level for oxygen within the transducer chamber. The invention includes an L-shaped housing where a transmitter/transducer is attached to one end of the housing and the receiver/transponder is positioned at the junction between the two substantially straight portions of the L-shaped housing. A straight transducer chamber is thereby provided, while simultaneously provided a housing design which minimizes reflected standing waves for detection by the receiver/transponder. The invention includes a sonic baffle positioned at the opposite end of the L-shaped housing from the transmitter/transducer which minimizes standing waves thereby improving the performance of the gas detection device. The invention also includes a sound buffer affixed to the interior of the L-shaped housing which further reduces the existence and reflection of standing waves for detection by the receiver/transponder. Temperature is monitored within the transducer chamber by an angularly offset temperature sensor.
