Patent number: 10416072Abstract: 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.Type: GrantFiled: June 17, 2015Date of Patent: September 17, 2019Assignee: Danfoss IXA A/SInventors: Allan Skouboe, Jesper Høyer, Carsten Moberg

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 where the sample gas are split into at least two flows where one is adapted for preventing the purge gas from influencing the measurement in a measuring region.Type: GrantFiled: June 17, 2015Date of Patent: February 20, 2018Assignee: Danfoss IXA A/SInventors: Carsten Moberg, Allan Skouboe, Jesper Høyer

Patent number: 9329121Abstract: The invention relates to a sensor having a filter arrangement, downstream of which there is arranged a detector arrangement, and an evaluating device connected to the detector arrangement. The filter arrangement has at least a first filter, the suspect filter, and at least one second filter, the reference filter(s). The first filter is configured as a band pass filter allowing the passage of a first predetermined band, the suspect band. The at least one second filter is configured as a band pass filter allowing the passage of a second predetermined band(s), the reference band(s). The detector arrangement has at least one detector associated with at least one of the filters. The band passes reference filters are distributed above and below the band pass of the suspect filter. The sensor with advantage could be utilized within the IR band, and could advantageously be used to detect CO2.Type: GrantFiled: April 16, 2010Date of Patent: May 3, 2016Assignee: Danfoss IXA A/SInventors: Jens Moeller Jensen, Arun Krishna, Lars Munch, Rainer Buchner, Thomine Stolberg-Rohr, Henrik Gedde Moos
