摘要： The present invention relates to a method for measuring the presence and/or the concentration of an analyte by means of a gas sensor arrangement and to a corresponding gas sensor arrangement. The gas sensor arrangement comprises a radiation-emitting radiation source, a gas measuring chamber, which may be filled with a test gas containing at least one analyte to be measured, and at least one radiation-detecting detector device which generates an output signal as a function of the presence and/or the concentration of the analyte. In order to be able to reduce the harmful effects of condensation water, which condenses in the gas measuring chamber, the gas measuring chamber according to the invention is heated before the measurement process, such that the wall of the gas measuring chamber assumes a temperature which lies above the dew point of the test gas.

摘要： A gas sensor arrangement comprises a gas measuring chamber containing a gaseous analyte. First and second radiation sources emit radiation. The first radiation source operates as a measuring radiation source and the second radiation source operates as a reference radiation source. The radiation is directed through the gas measuring chamber and into a detector that generates an output signal depending on the presence of the gaseous analyte. A control device evaluates the output signal from the detector. The control device interchanges the operation of the first and second radiation sources after a predetermined service life.

摘要： The invention relates to a method for measuring the presence and/or the concentration of an analyte using a gas sensor assembly and to a corresponding gas sensor assembly. The gas sensor assembly comprises, in particular, a radiation-emitting radiation source (102), a gas measurement chamber (104) which may be filled with a test gas (110) containing the at least one analyte to be measured, and at least one detector device (108) which detects the radiation (116) and generates an output signal which is dependent on the presence and/or the concentration of the analyte. In order to meet increased safety requirements and to avoid the drawbacks of the known systems without inadmissible increased complexity and overall size, the radiation source emits radiation in the form of pulses and, during each radiation pulse, a large number of individual values (304) are recorded for generating an average measured value, the first of the large number of individual values being compared, during the first radiation pulse, with a predetermined threshold value and an alarm signal (136) being generated if the threshold value is exceeded.
