Abstract
A coplanar process fluid pressure sensor module is provided. The module includes a coplanar base and a housing body. The coplanar base has a pair of process fluid pressure inlets, each having an isolator diaphragm. The housing body is coupled to the coplanar base at an interface between the coplanar base and the housing body. A differential pressure sensor is operably coupled to the pair of process fluid pressure inlets, and is disposed proximate the coplanar base within the housing body.
Claims20
A coplanar process fluid pressure sensor module, the module comprising:
- a rectangular coplanar base having a pair of process fluid pressure inlets, each having an isolator diaphragm adjacent an outer face, the coplanar base having a flat surface opposite the inlets which includes a recess formed therein;
- a housing body coupled to the coplanar base at an interface between the coplanar base and the housing body, the interface arranged on the coplanar base opposite the outer face;
- a differential pressure sensor operably coupled to the pair of process fluid pressure inlets, and being disposed adjacent the coplanar base within the housing body and positioned at least partially in the recess;
- and
- a stiffener plate having an aperture through which the housing body passes, the stiffener plate configured to clamp the housing body between itself and the coplanar base.
A coplanar process fluid pressure sensor module, the module comprising:
- a rectangular steel coplanar base having a pair of process fluid pressure inlets, each having an isolator diaphragm adjacent an outer surface, the coplanar base having a flat surface opposite the inlets which includes a recess formed therein;
- a cylindrical housing body coupled to the coplanar base at an interface between the steel coplanar base and the housing body, the cylindrical housing body having an externally threaded portion, the interface arranged on the steel coplanar base opposite the outer surface;
- a differential pressure sensor operably coupled to the pair of process fluid pressure inlets, and being disposed proximate the coplanar base within the housing body and positioned at least partially in the recess;
- and
- a stiffener plate having an aperture through which the housing body passes, the stiffener plate configured to clamp the housing body between itself and the coplanar base.
