An industrial process transmitter includes a housing, sensor circuitry, transmitter circuitry, and a radiation shield. The sensor circuitry is contained in the housing, and is configured to sense a process parameter and generate a sensor output that is indicative of the sensed process parameter. The transmitter circuitry is contained in the housing, and is configured to communicate the sensed process parameter to an external unit. The radiation shield substantially surrounds a portion of the housing containing the sensor circuitry and shields the sensor circuitry from gamma radiation.

A transmitter flange includes a flange body having a valve opening therein, the valve opening having a valve seat, and an internal valve configured to be retained in the valve opening. A retaining ring may be configured to thread into the valve opening to further retain the internal valve within the opening.

Internal valve transmitter flange

A field device assembly includes an industrial process field device, a flange and a sealing and electrically insulating system. The field device includes a pressure sensor and a housing containing the active component. The housing includes a base having a base interface, which includes a first base process opening. The flange is attached to the base of the housing and includes a coplanar interface having a first flange process opening. The sealing and electrically insulating system includes a gasket that includes a dielectric material. A first process opening in the gasket is aligned with the first base process opening and the first flange process opening. A first surface of the gasket engages the base interface, and a second surface of the gasket that is opposite the first surface engages the coplanar interface. The gasket electrically insulates the housing of the field device from the flange.

Field device interface seal and electrical insulation

A valve manifold includes a manifold and a valve. The manifold has a recess, a first fluid port, and a second fluid port. The valve is disposed entirely within the recess and is fluidically interposed between the first fluid port and the second fluid port. The valve has a rotatable needle having an end that is configured to be displaced relative to a valve seat upon rotation.
