    摘要： An apparatus, system and method maximizes efficiency and accuracy of measuring an oxygen concentration of a measured gas by varying a flow of oxygen ions within a measuring cell (202) in accordance with an output signal of an oxygen sensor cell (206). The pump current (208) through a pump cell (204) is switched between a constant positive current and a constant negative current when upper and lower thresholds of the output signal are reached. The pulse width ratio of the square wave produced by the varying current is compared to a pulse width ratio function derived from a calibration procedure to determine the oxygen concentration of the measured gas.

    摘要： An exhaust guide guides exhaust gases within an exhaust system to an intake portion of a sensor when an input port and an output port of the exhaust guide are positioned within an exhaust gas flow. A high pressure region formed at the input port and a low pressure region formed at the output port facilitate the flow of the gases through a chamber housing that at least houses the intake portion of the sensor. Contamination of the sampled gases by outside air is minimized. In some configurations, the sensor is mounted outside of the exhaust system to increase the thermal isolation between the sensor and the exhaust system improving the performance and increasing the useful life of the sensor.

    摘要： An apparatus, system and method maximizes efficiency and accuracy of measuring an ion concentration of a measured fluid by varying a flow of ions within a measuring cell in accordance with an output signal of a sensor cell. The pump current through a pump cell is switched between a constant positive current and a constant negative current when upper and lower thresholds of the output signal are reached. The pulse width ratio of the square wave produced by the varying current is compared to a pulse width ratio function derived from a calibration procedure to determine the ion concentration of the measured fluid. In one embodiment, the functions of the pump cell and sensing cell are performed by a single electrochemical cell.

    摘要： The invention provides for a method and device for determining a gas pressure and temperature in a hollow space, including a fuel/air mix in an internal combustion engine combustion chamber. According to the invention, pressure and temperature are detected by means of a measuring element (5) of an ultrasound transducer/pressure sensor combined unit, said measuring element acting both as a pressure measuring element and an ultrasound transducer element to determine temperature. Therefor, said measuring element can be operated at given moments, on one hand as a pressure measuring element and on the other hand as an ultrasound transducer element or continuously, as a pressure measuring element, and furthermore as an ultra-sound transducer element superimposed with the latter. In that case, it is provided that signals should be conveniently separated for the measuring element output signal. The invention can be used, for instance, to determine air volumes for car internal combustion engines.

    摘要： A sensor assembly includes a voltage source, a sensor electrode, a grounded assembly, an integration capacitor, and a current meter. The sensor electrode is coupled to the voltage source to receive a voltage. The sensor electrode is disposed within a directed and controlled exhaust flow to facilitate particle agglomeration into particulate matter structures at a surface of the sensor electrode. The grounded assembly is coupled to a ground reference and disposed at a distance from the sensor electrode. The integration capacitor is coupled to a negative side of the voltage source to integrate in time current pulses from charge transfers from the sensor electrode of the particulate matter structures. The current meter is coupled to the voltage source to measure an integrated value of current supplied to the voltage source in response to charge transfers from the sensor electrode to the particulate matter structures in the exhaust flow.
