  • Duct sensor with duct probe for sampling a fluid from a duct and method of operation
    Patent number: 11965807
    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) n 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).
