摘要：
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.
