    Abstract: Une sonde de détection de glace (10) détecte un dépôt de glace à partir d'une masse d'air s'écoulant par rapport à la sonde (10). La sonde (10) comprend un support (12) pour monter la sonde (10) et lui permettre de recevoir le flux d'air, ainsi qu'un élément (30) formé sur un substrat ayant une surface de détection (32) qui reçoit directement le flux d'air. L'élément (30) chauffe la surface de détection (32) pour faire fondre un dépôt de glace qui s'y est formé. L'élément (30) détecte également la température de la surface de détection pendant le chauffage et fournit un signal de sortie représentatif de cette température.

    Abstract: A process fluid flow device (12) includes process communication circuitry (20), a processor (26), and measurement circuitry (28). The process communication circuitry (20) is configured to communicate with at least one additional process device. The processor (26) is coupled to the process communication circuitry (20) and is configured to execute instructions to provide a plurality of cycles, wherein each cycle includes a number of flow- related calculations. Measurement circuitry (28) is operably coupleable to a plurality of process variable sensors to obtain an indication of differential pressure during each cycle, and to obtain static pressure, and process fluid temperature. The processor (26) is configured to compute a process fluid flow value using a current differential pressure sensor indication and at least one flow-related value calculated during a previous cycle. The process communication circuitry (20) communicates the computed process fluid flow value to the at least one additional process device.

    Abstract: A flow tube (10) has a metal outer tube (12) and is lined (26) with an ETFE fluoropolymer that is resistant to corrosive chemicals and mechanical damage even at high temperatures. The inner surface (22) of the metal tube (12) is coated with a bonding metal (28) that can be securely bonded to the outer metal tube (12) and also forms a strong bond with ETFE fluoropolymer. After the bonding metal (28) has been applied, a layer (26) of a desired thickness of the ETFE fluoropolymer is molded in place to form an inner liner for the flow tube (10).

    Abstract: A pressure transmitter (100) comprises a metal wall (102) separating a process pressure chamber (104) from an electronics compartment (106). The metal wall (102) has a stepped bore (108) with a bore shelf (110) facing the process pressure chamber (104). A metal header (112) has a stepped outer rim (114) with a header shelf that contacts the bore shelf. The metal header (112) includes at least one electrical feedthrough (122,124) with a glass-to-metal seal (126,128) adjacent the stepped outer rim (114). A welded seal (130) seals the stepped outer rim to the stepped bore.
