Abstract: A process fluid pressure measurement probe includes a pressure sensor formed of a single-crystal material and mounted to a first metallic process fluid barrier and disposed for direct contact with a process fluid. The pressure sensor has an electrical characteristic that varies with process fluid pressure. A feedthrough is formed of a single-crystal material and has a plurality of conductors extending from a first end to a second end. The feedthrough is mounted to a second metallic process fluid barrier and is spaced from, but electrically coupled to, the pressure sensor. The pressure sensor and the feedthrough are mounted such that the secondary metallic process fluid barrier is isolated from process fluid by the first metallic process fluid barrier.

Abstract: A wireless field device assembly comprises a process sensor, a housing, a power module, and a processor. The process sensor is configured to monitor a process variable and produce a sensor signal. The housing encloses an interior space of the wireless field device. The power module comprises an energy storage device and a connection to a local power source, and is configured to be housed in the wireless field device. The processor is located within the interior space, and is powered by the power module. The processor produces a fault signal value used to differentiate between energy storage device faults, local power source faults, and no-fault states.
