Abrégé
(EN) 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).
(ZH) 用于从管道(10)中的主要流体流(Fm)中采样流体的管道探测器(20)限定了伸长的供应通道(21)和伸长的排出通道(22)。供应通道具有至少一个流入开口(23),所述至少一个流入开口用于将部分流(Fp)从主要流体流转移到供应通道中;排出通道具有至少一个流出开口,所述至少一个流出开口用于在部分流已经经过环境传感器(30)之后使部分流从排出通道返回到主要流体流中。管道探测器还包括至少一个补偿开口(26),所述至少一个补偿开口在位于供应通道和排出通道的封闭端和开口端之间的区域中连接供应通道和排出通道。通过存在补偿开口(26),喷射流(Fj)被产生,当管道探测器暴露于主要流体流(Fm)时,喷射流用于减小供应通道与排出通道之间的压差。
