Abstract:
1. A process fluid pressure sensing system comprising: a process fluid pressure transmitter having first and second pressure inlets, the process fluid pressure transmitter being configured to obtain a measurement relative to pressures applied at the first and second pressure inlets and provide a process variable output based on the measurement; a process manifold operably coupled to a process fluid, the process manifold having first and second pressure outlets; a first high-pressure coupling joining the first pressure outlet of the process manifold to the first pressure inlet of the process fluid pressure transmitter, the first high-pressure fluid coupling being configured to accommodate misalignment between the first pressure outlet and the first pressure inlet, the first high pressure coupling including a tube having a tube end and a recess, and at least one of the tube end and recess has a spherical surface to accommodate misalignment between the first pressure outlet and the first pressure inlet; and a second high-pressure coupling joining the second pressure outlet of the process manifold to the second pressure inlet of the process fluid pressure transmitter, the second high-pressure fluid coupling being configured to accommodate misalignment between the second pressure outlet and the second pressure inlet.
