Abstract: A regulation device for regulating a mixing ratio (x) of a gas mixture comprises a first conduit ( 1 ) for carrying a flow of a first gas (e.g., air) and a second conduit (2) for carrying a flow of a second gas (e.g., a fuel gas). The first and second conduits (1, 2) open out into a common conduit (3) in a mixing region (M) to form the gas mixture. A first sensor (SI) is configured to determine at least one thermal parameter of the gas mixture downstream from the mixing region. A control device (10) is configured to receive, from the first sensor, sensor signals indicative of the at least one thermal parameter of the gas mixture and to derive control signals for adjusting device (VI) acting to adjust the mixing ratio, based on the at least one thermal parameter.

Abstract: A duct probe (20) for sampling a fluid from a main fluid flow (Fm) in a duct (10) defines an elongated supply channel (21) and an elongated discharge channel (22). The supply channel has at least one inflow opening (23) for diverting a partial flow (Fp) from the main fluid flow into the supply channel, and the discharge channel has at least one outflow opening for returning the partial flow from the discharge channel into the main fluid flow after it has passed an environmental sensor (30). The duct probe further comprises at least one compensation opening (26) that connects the supply channel and the discharge channel in a region that is located between their closed and open ends. By the presence of the compensation opening (26), a jet flow (Fj) is created, which acts to reduce a pressure difference between the supply channel and the discharge channel when the duct probe is exposed to the main fluid flow (Fm).

An opening (4) in the measurement cell is provided for a gas to enter the measurement volume (3). In the first volume (31) and on a front side (11) of the substrate (1) are arranged: An electromagnetic radiation source (7) for emitting electromagnetic radiation (8) through an aperture (18) in the reflective shield (17) into the second volume (32); and a pressure transducer (6) communicatively coupled to the second volume (32) for measuring a sound wave (9) generated by the component in response to an absorption of electromagnetic radiation (8) by the component. At least a portion of a surface (171) of the reflective shield (17) facing the second volume (32) is made of a material reflecting electromagnetic radiation (8).
