CPC classification number: G01L19/0007
Abstract: An in-line pressure transmitter (10) for sensing an absolute or gage process pressure of a process fluid includes an in-line process coupling (14). The coupling has a mounting member (16) which includes a substantially flat mounting face (18) and a bore generally aligned with an isolation diaphragm assembly (30). The member (16) is configured to mount to a flat process coupling.

Abstract: An assembly for aligning and supporting an adapter flange for connecting fluid pressures to a pressure sensor body in place on the body and to keep the flange in an unsealed condition to prevent pressurizing the body and flange until installation of permanent fasteners. The support fasteners retain the flange spaced from the body sufficiently so that the flange will not seal. This will prevent accidentally pressurizing the flange and pressure sensor body until permanent fasteners have been installed. The body and flange are shipped with at least one extra set of permanent fasteners different in length from the fasteners used on the flange to permit adding adapters for a process connection. When a different thickness adapter is used for process connection, only the correct length fasteners will be capable of being threaded into the threaded openings and also seal the flange or adapter.

Abstract: A pressure transmitter has a pressure sensor coupled to an isolator diaphragm by a fill fluid such as oil. According to the invention, means are provided for measuring the position of the isolator diaphragm and comparing the measured position with an expected position to give an indication of fill fluid leakage. Non-contact arrangements such as capacitive and ultrasonic techniques are disclosed for measuring isolator diaphragm position, as well as contacting arrangements such as switches. The fill fluid loss arrangement can be incorporated into a two-wire transmitter, which transmitter can be made to send a warning signal to a control unit when fill fluid loss is detected.

Abstract: An assembly for aligning and supporting an adapter flange for connecting fluid pressures to a pressure sensor body in place on the body and to keep the flange in an unsealed condition to prevent pressurizing the body and flange until installation of permanent fatteners. The support fasteners retain the flange spaced from the body sufficiently so that the flange will not seal. This will prevent accidentally pressurizing the flange and pressure sensor body until permanent fasteners have been installed. The body and flange are shipped with at least one extra set of permanent fasteners different in length from the fasteners used on the flange to permit adding adapters for a process connection.

Abstract: A manifold includes a body having generally planar inlet surface. The inlet surface includes a first inlet and a second inlet adapted for coupling to a pressurized process fluid. An outlet surface on the manifold is adapted for coupling to a co-planar transmitter and is at angle relative to the inlet surface. The manifold includes an equalizing valve surface opposite the outlet surface, and a perimeter therebetween. The outlet surface includes first and second outlets in fluid communication with the first and second inlets, respectively.

The body (11) and flange (15) are shipped with at least one extra set of permanent fasteners (46, 50) different in length from the fasteners (23) used on the flange (15) to permit adding adapters (47) for a process connection. When a different thickness adapter (47) is used for process connection, only the correct length fasteners will be capable of being threaded into the threaded openings and also seal the flange or adapter.
