Abstract: A wireless power and communication unit (100, 200, 300, 350, 360, 400) for field devices (14) is configured to connect to a field device (14) and provide operating power and wired digital communication between the unit (100, 200, 300, 350, 360, 400) and the field device (14). RF circuitry (366) in the unit (100, 200, 300, 350, 360, 400) is configured for radio frequency communication. In one embodiment, power supply circuitry (365) in the unit includes one or more solar power cells (116) that convert solar energy into electricity to power both the unit (100, 200, 300, 350, 360, 400) and the field device (14). The unit (100, 200, 300, 350, 360, 400) interacts with the field device (14) in accordance with a standard industry communication protocol. The unit (100, 200, 300, 350, 360, 400) communicates wirelessly with an external device, such as a control room (12), based upon the interaction with the field device (14) .

Abstract: A pressure sensor module (50) and method for preinstallation without a converter module. The pressure sensor module (50) is hermetically sealed and can remain undamaged in an installation environment without a converter module. The pressure sensor module (50) can be assembled later with a converter module in the installation environment. The pressure sensor module (50) includes an isolator (54), a pressure sensor (58) and a circuit (60) that provides a bus (64) for energization, control and a digital pressure output. The bus (64) is connected to contacts (68) in an insulating feedthrough. An integrally formed hermetic external support structure surrounds the pressure sensor (58) and circuit (60). The hermetic external support structure has a threaded process fluid inlet (74) around the isolator (54), and a threaded support sleeve (76) supporting the feedthrough.
