Abstract: The cavities in a cell casing have silicone oil adapted to receive pressure and exert corresponding force on diaphragm. The diaphragm is deflected based on difference in received pressure. Electrodes defining variable capacitors are coupled to center and edges of interior wall and coupled to conductive portion of diaphragm. The cell casing has interior walls with edge surrounding center region and defining a cavity, portioned by deflectable diaphragm arranged between interior walls. Independent claims are also included for the following: (a) process pressure transmitter; (b) differential pressure measuring method; (c) error compensating method in measuring differential pressure.

Abstract: Disclosed is a bi-directional differential pressure flow sensor that is configured to establish a direction and flow rate of a fluid flow. The flow sensor includes a flow restriction member, a differential pressure sensor, and processing electronics. The flow restriction member is configured to produce a pressure drop when placed inline with the fluid flow. The differential pressure sensor is embedded or integral with the flow restriction member and produces a differential pressure signal that is indicative of the pressure drop. The processing electronics produces a flow rate signal that is indicative of the direction and flow rate of the fluid flow as a function of the differential pressure signal.

Abstract: A transmitter of the type used in the process control industry includes a sensor for sensing a process variable and a transmitter body having a sensor coupling. A sensor extension couples to the sensor coupling and includes a sensor coupling face. A first flange interface has a process face which provides a process connection and a sensor face which provides a sensor connection. A passageway couples the process connection to the sensor connection. The first flange interface is coupled to the sensor extension by a coupling mechanism. The sensor extension and the first flange interface may be moved throughout, a range of positions relative to one another.

Abstract: In this invention, a multivariable transmitter providing an output representative of mass flow has a dual microprocessor structure. The first microprocessor compensates digitized process variables and the second microprocessor computes the mass flow as well as arbitrating communications between the transmitter and a master. In a second embodiment of the present invention, a first microprocessor compensates digitized process variables, a second microprocessor computes an installation specific physical parameter such as mass flow and a third microprocessor arbitrates real-time communications between the transmitter and a master.

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.
