发明名称 REVERSE FLOW GAS GAUGE PROXIMITY SENSOR.
摘要 <p>A gas gauge proximity sensor supplying gas in a reverse flow direction from the injection chamber to the measurement chamber. Supplying gas in a reverse flow direction enables the transient behavior in the sensor to more rapidly stabilize, with a resulting increase in bandwidth. Optionally, a scavenger chamber can be used to remove the excess gas by locating a scavenger aperture of the scavenger chamber in close proximity to the exit aperture of the injection chamber. A bridge proximity sensor can be used with a reference chamber to receive gas flow from a location close to the exit aperture of the injection chamber in order to reduce common mode errors.</p>
