    Abstract: A micromachined device (32) receiving a pressurizable fluid has a plurality of layers (34, 36) bonded together along at least one bond interface (35), the bond interface having a terminus bordering the pressurizable fluid. In a vicinity of at least one bond interface (35) at least one layer (34, 36) has a shape that reduces a stress magnitude near the bond terminus. In a preferred embodiment a width of at least one layer (34) increases toward the bond interface (35), to increase the pressure at which the device can operate without fracturing. In another embodiment, both layers (34, 36) bordering the bond interface (35) have widths in the vicinity of the bond interface (35) that increase toward the bond interface (35). Alternately, the layers (34, 36) have walls shaped such that, for a reference line perpendicular to the bond interface (35) and passing through an end of the bond interface (35) bordering the cavity, the cavity protrudes between the reference line and at least one of the walls.

    Abstract: A process control system (10) utilizes wireless transceivers to divorce the field devices (14, 30) from traditional wired network topologies. By providing field devices (14, 30) with wireless transceivers (22) and shared wireless transceivers (36) for adapting wired field devices (30), the field device network may be adapted to any number of network topologies without concern for additional wiring costs. Specifically, a power supply (18, 26) can be provided for each field device (14) or for groups of field devices, as needed. Thus, the entire network can receive power from a single power bus (32), without expensive power filtering. In addition, the network can be a hybrid in which part of the information is transmitted and received over wired lines and part is transmitted and received over wireless communications.

    Abstract: A deflecting diaphragm differential pressure sensor (10) is formed so all electrical elements (30A-30D) and connections (34B) from external circuitry to the sensor (10) are isolated from the pressure media. The deflecting, pressure sensing diaphragm (22) is made of a semi-conductor material, having piezoresistors disposed on a surface (25) thereof to form strain gages to sense deflection of the diaphragm (22). The strain gage resistors are media isolated by a layer that overlies the strain gage resistors. All forms of the invention provide environmental protection for the electrical connections for external circuitry, which are subject to corrosion from the pressure media.
