    Abstract: A process analytic system includes an analytic sensor configured to sense a characteristic of a fluid. The process analytic system also includes measurement circuitry coupled to the analytic sensor and configured to generate an indication of the characteristic of the fluid. The process analytic system includes a processor coupled to the measurement circuitry and configured to receive the indication of the characteristic of the fluid and calculate a sensor-related output based on the indication of the characteristic of the fluid. In addition, the process analytic system includes a diagnostics component configured to determine a rate of degradation of the analytic sensor based on the sensor-related output and a reference value, wherein the rate of degradation is compared to a pre-selected threshold.

    Abstract: An industrial process field device includes first and second loop terminals configured to couple to a two-wire process control loop. Device circuitry is powered from the process control loop and monitors a process variable or controls a control device. A current regulator is in series with the loop terminals, and regulates a loop current. A first shunt voltage regulator regulates a voltage across the device circuitry. Supplemental circuitry is connected in series with the first shunt voltage regulator and the second loop terminal, and is powered by power from the two-wire process control loop shunted through the first shunt voltage regulator. A second shunt voltage regulator is connected in series with the first shunt voltage regulator and the second loop terminal, and in parallel with the supplemental circuitry, and regulates a voltage across the supplemental circuitry.

    Abstract: A process fluid flow system includes a first pipe skin sensor and a second pipe skin sensor. The first pipe skin sensor is disposed to measure an external temperature of a process fluid conduit at a first location on the process fluid conduit. The second pipe skin sensor is disposed to measure an external temperature of a process fluid conduit at a second location on the process fluid conduit. Measurement circuitry is coupled to the first and second pipe skin sensors. A controller is coupled to the measurement circuitry and is configured to identify a process fluid flow condition based on signals from the first and second pipe skin sensors and to output an indication of the process fluid flow condition.

    Abstract: A pH sensor for a single-use container includes a plunger sleeve configured to couple to a flange of the single-use container. A plunger is axially movable within the plunger sleeve between a storage position and an operating position. A pH sensing element coupled to the plunger wherein the pH element is disposed within a storage chamber in the storage position and is configured to be exposed to an interior of the single-use container in the operating position. In one example, a temperature sensitive element is disposed within the pH sensor and configured to sense temperature proximate the pH sensing element. In another example, a lock member is coupled to the plunger, where the lock member has a locked position and an unlocked position, the lock member being configured to inhibit movement of the plunger when in the locked position. In yet another example, the plunger includes at least one filling channel that allows access to a reference fill chamber when the plunger is in a filling position.

    Abstract: A level transmitter includes an analog-to-digital convertor clock signal generator that receives a transmitter clock signal that is used to establish when an incident signal is transmitted toward a material boundary. The analog-to-digital convertor clock signal generator uses the received transmitter clock signal to generate an analog-to-digital convertor clock signal. An analog-to-digital convertor samples an analog waveform based on the analog-to-digital convertor clock signal and generates a digital value for each sample of the analog waveform. An analysis module analyzes the digital values to determine a distance to the material boundary.
