    摘要: A probe for an IR or UV sensor comprising a light emitter and detector is described comprising a lens. The detector detects the spectrums of the emitted light after it has passed a gas to be measured. The sensor of the present invention is especially suitable for such as harsh or aggressive environments measuring the exhaust gasses, for example in ships, vehicles, chimneys etc., and comprises purge gas protections for delicate optical parts to prevent particles etc. from the exhaust gas depositing on the optics. The sensor further has a flow of sample gas from the gas to be measured being adapted to prevent the purge gas from inferring with the measurements.

    摘要: The invention relates to a sensor having a filter arrangement, downstream of which there is arranged a detector arrangement, and an evaluating device which is connected to the detector arrangement, the filter arrangement has at least a first filter, the suspect filter, which is configured as a band pass filter allowing the passage of a first predetermined band, the suspect band, at least one second filter, the reference filter(s), which is configured as band pass filters allowing the passage of a second predetermined band(s), the reference band(s), and where the detector arrangement has at least one detector associated with the at least one of the filters. The sensor uses the band pass filters to measure the temperature of an emitting source. The sensor with advantage could be utilized within the IR band, and could advantageously be used to detect CO

    摘要: A probe for an IR or UV sensor comprising a light emitter and detector is described comprising a lens (2). The detector detects the spectrums of the emitted light after it has passed a gas to be measured (6). The sensor of the present invention is especially suitable for such as harsh or aggressive environments measuring the exhaust gasses, for example in ships, vehicles, chimneys etc., and comprises purge gas protections for delicate optical parts to prevent particles etc. from the exhaust gas depositing on the optics. The sensor further has a flow of sample gas from the gas to be measured being adapted to prevent the purge gas (7) from interfering with the measurements where the sample gas is split into at least two flows (6a, 6b, 6c) where one (6c) is adapted for preventing the purge gas from influencing the measurement in a measuring region (5).

    摘要: Gas sensor enable to measure gas based on the absorption bands of radiation characteristic to the gas of interest, where the sensor is able to measure gases of temperatures usually too high for the delicate parts of the sensor to endure. The present invention introduces a cooling device connected to the sensor for ensuring a lowered temperature in the vicinity of the delicate parts.
