    Abstract: An industrial process variable transmitter includes a process variable sensor configured to sense a process variable. Measurement circuitry is coupled to the process variable sensor and provides a measured output as a function of the process variable. Output circuitry includes a loop connection configured to couple to a process control loop. An optical sensor receives the measured output from the measurement circuitry. A switching device applies pulses to the process control loop in response to an output from the optical sensor. Power supply circuitry powers the optical sensor, a comparator, and/or the switching device with power received from the process control loop and loop connection.

    Abstract: A process variable transmitter is configured as a flowmeter for measuring flow of a process fluid through a conduit. The transmitter includes a pitot tube extending into the conduit which creates a differential pressure in the process fluid due to flow of the process fluid. An upstream process variable sensor is mounted on the pitot tube and coupled to the flow of process fluid to sense an upstream process variable of the process fluid. A downstream process variable sensor is mounted on the pitot tube downstream of the upstream process variable sensor and coupled to the flow of process fluid to sense a downstream process variable of the process fluid. Measurement circuitry determines the flow of the process fluid based upon the upstream process variable and the downstream process variable.

    Abstract: A diagnostic field device for detecting a condition of a process conduit includes an infrared detector comprising a plurality of pixels configured to receive infrared radiation from the process conduit and responsively provide a plurality of pixel outputs. A first pixel of the plurality of pixels is configured to receive infrared radiation from a first location on the process conduit. A second pixel of the plurality of pixels is configured to receive infrared radiation from a second location on the process conduit. A memory contains thermal profile information which relates an output from the first pixel to a first temperature at the first location and relates an output from the second pixel to a second temperature at the second location. A microprocessor identifies a process anomaly based upon outputs from the first and second pixels. Output circuitry provides a diagnostic output indicative of the identified process anomaly.

    Abstract: A process variable transmitter is used to measure a process variable, and, in doing so, dynamically changes the resolution of the A/D converter based upon the measured value of the analog input signal. This can be done by automatically adjusting the configurable resolution gain adjustment based on the value of the analog signal being measured, by normalizing the input signal being measured so that it is centered in an optimal resolution window of the A/D converter, or by adjusting a voltage reference provided to the A/D converter.
