Abstract: A pressure transmitter has a pressure transducer in a transmitter housing. The transmitter housing includes a groove or a notch defining a flexure closely proximate a housing outer rim. The outer rim receives a large clamping force from a flange and is deflectable about the flexure for reducing transmission of axial and radial components of the clamping force from the housing outer rim to the transducer, which forces can cause distortions to the pressure transducer. Unevenly distributed clamping forces caused by differential thermal expansion of the flange, bolts and housing, are isolated from the transducer thereby reducing measurement errors. Further, transmission of hysteretic radial forces from the transmitter housing to the transducer caused by friction when the flange slides across the pressure transmitter housing, each having different thermal coefficients of expansion, is also reduced.

Abstract: The vane adjusting machine for increasing or decreasing the flow through a turbine nozzle includes a bending tool for attachment to a wrist of a robot arm whose operation and function is controlled by computer hardware and software. The bending tool preferably includes a floating head assembly and an interchangeable jaw sub-assembly. In operation, a turbine nozzle is subjected to an airflow test. Subsequently, the turbine nozzle is mounted on a rotatable work surface and a first vane is initialized to a bending station location. The bending tool controlled by the computer then locates and bends the first vane to a desired orientation based on the airflow test results. On completion of the bending of the first vane, the bending tool is removed from proximity with the first vane, and the computer controls the rotation of the worktable to position a second vane at the bending station location.
