摘要： A transmitter for measuring a process variable of an industrial process includes a sensor adapted to measure the process variable and to generate a sensor output. A mode selector is adapted to select between operational modes. At least one operational mode is related to an operational range of the sensor. Circuitry is adapted to compensate the sensor output according to the at least one operational mode and to generate a transmitter output representative of the measured process variable.

摘要： An overpressure vent in a transmitter housing of a process transmitter. The transmitter is configured for coupling to an industrial process and measuring a process variable. The transmitter includes an enclosure having a cavity formed therein. A process coupling is configured to couple the cavity to the industrial process. The overpressure vent is arranged to vent an overpressure in the cavity to outside of the transmitter enclosure.

摘要： A method and apparatus are provided for allowing a field device to select a data communication provider among a plurality of available data communication providers. Preferably, the method includes periodically, or selectively, assessing the strengths and efficacy of data communication on one or more alternate data communication providers. The data communication provider with the strongest signal and/or most effective data communication is selected for use by the field device. Preferably, the field device logs events where it switches among data communication providers.
