Abstract: An electronic system for detecting and tracking the resonant frequency of a photoacoustic cell is described. The system includes and makes use of inherent signal acquisition properties. The detection and tracking circuitry promotes acoustic oscillation at the cell resonant frequency while the amplitude of the acoustic oscillation is automatically controlled at a specific reference level. Under normal operation, a change in system oscillation amplitude with respect to the reference level is considered to be the result of additional acoustic excitation other than that provided by the electronic system. Changes in the oscillation amplitude, as compared to a reference level, produce an error signal which is directly related to the additional acoustic excitation. The system is particularly useful in measuring gaseous phase materials over a wide dynamic range of concentrations.

Abstract: In a method for determining the exhaust gas temperature, the internal resistance of a lambda sensor is measured, and it is determined whether lean or rich mixture is present. Depending on which mixture type is present, the exhaust gas temperature associated with the measured internal resistance value is read out from one of two internal resistance value/exhaust gas temperature characteristic curves. This method can be used correspondingly for determining the sensor temperature from the internal resistance.The exhaust gas temperature determined as above only applies accurately for steady-state cases. In order to obtain satisfactory values even in non-steady-state cases, the exhaust gas temperature is averaged in a sliding manner. The present exhaust gas temperature is determined from the particular average value and the particular rise in the exhaust gas temperature/time curve.The mentioned methods permit the exhaust gas temperature to be determined without a separate temperature measuring element.
