| titleOfInvention | Measuring gas components together with a paramagnetic gas |
| abstract | The invention concerns a gas analyzer, which comprises: an electromagnet (5) that has an air gap (16); a power source (60) for supplying cyclically variable electrical current/voltage to said electromagnet; a sample gas conduit (1) and a reference gas conduit (2) opening into said air gap; an exit conduit (18, 19) communicating with said air gap for removing the intermixed sample and reference gases; pressure detecting microphone or microphones (3, 4) connected to said sample gas conduit (1) and to said reference gas conduit (2) for sensing gas pressures at a first acoustic measuring frequency ( f A1 ) in the respective conduits for giving at least one acoustic pressure signal component (S 1 and/or S2); and electronics (29) connected to said microphone(s) to receive said acoustic pressure signal component or components to form at least a first intermediate output signal (SI A1 ) describing content of a paramagnetic gas component in the sample gas. Further in the gas analyzer: said pressure detecting microphone(s) are adapted for sensing gas pressures at a second acoustic measuring frequency ( f A2 ), and giving at least a second acoustic pressure signal component (S3 and/or S4); and said electronics receive said second acoustic pressure signal component or components to form a second intermediate output signal (SI A2 ) including content data of a second gas component in the sample gas. |
