    Abstract: A wireless field device for use in an industrial process includes input/output terminals configured to couple to a process interface element. A discrete input/output channel is configured to receive a discrete input signal from the process interface element through the input/output terminals when configured as a discrete input channel. The discrete input/output channel is further configured to provide a discrete output to the process interface element through the input/output terminals when configured as discrete output channel. Wireless communication circuitry transmits and receives information. A controller is configured to provide a discrete output signal to the process interface element in response to information received by the wireless communication circuitry when the discrete input/output channel is configured as a discrete output channel, and further configure to receive a discrete input signal from a process variable sensor and responsively provide an output using the wireless communication circuitry when the discrete input/output channel is configured as a discrete input channel. An external power supply input couples to an external power supply. A load adapter module couples to the discrete output signal and the external power supply input and includes a switch configured to connect the process interface element to the external power supply in response to the discrete output signal.

    Abstract: A wireless process variable transmitter for use in an industrial process includes a process variable sensor configured to sense a process variable of the industrial process. Measurement circuitry connected to the process variable sensor provides an output related to the sensed process variable. Wireless communication circuitry connected to the measurement circuitry wirelessly transmits information related to the sensed process variable to a remote location. A removable industrial power module is configured to hold a replaceable battery and provide power to the process variable sensor, the measurement circuitry and the wireless communication circuitry. Battery test circuitry in the removable industrial power module connects to the replaceable battery and provides a visual output related to a condition of the replaceable battery.

    Abstract: A vibrating fork liquid level switch includes a vibrating fork assembly arranged to vibrate at a first frequency when in contact with a process fluid and at a second frequency when in contact with air. A drive circuit connected to the vibrating fork assembly is configured to drive the vibrating fork assembly into oscillation. Sense circuitry senses an oscillation frequency of the vibrating fork assembly. Output circuitry provides a first output when the sensed oscillation is at the first frequency and a second output when the sensed oscillation is at the second frequency. Control circuitry controls power applied to the vibrating fork assembly by the drive circuit between a first and a second power level. Verification circuitry verifies the oscillation frequency of the vibrating fork assembly when power applied to the vibrating fork assembly by the drive circuitry is changed.

    Abstract: A polymeric fluid sensor includes an inlet configured to receive fluid and an outlet. A polymeric tube is fluidically interposed between the inlet and the outlet and has a first sensing location with a first sidewall thickness and a second sensing location, spaced from the first sensing location, with a second sidewall thickness. A sleeve is disposed about the polymeric tube. The first sidewall thickness is less than the second sidewall thickness and a first sensing element is disposed at the first location and a second sensing element is disposed at the second location. In another example, the first and second sidewall thicknesses are the same and a fluid restriction is disposed within the polymeric tube between the first and second sensing locations.

    Abstract: A loop-powered field device includes a plurality of terminals coupleable to a process communication loop and a loop control module coupled to one of the plurality of terminals and configured to control an amount of current flowing through the loop control module based on a control signal. A field device main processor is operably coupled to the loop control module to receive its operating current (I_Main) from the loop control module and is configured to provide the control signal based on a process variable output. A low power wireless communication module is operably coupled to the loop control module to receive its operating current (I_BLE) from the loop control module. The low power wireless communication module is communicatively coupled to the field device main processor. The low power wireless communication module has an active mode and a sleep mode. The low power wireless communication module is configured to obtain a measurement of operating current (I_BLE) available while the low power wireless communication module is in the sleep mode and modify an active cycle of the low power wireless communication module based on the measurement of operating current (I_BLE).

    Abstract: An industrial process field device includes a piezoelectric transducer, a sensor circuit, a test circuit, a controller and a communications circuit. The sensor circuit generates a sensor signal indicating a process variable based on a voltage across the piezoelectric transducer. The test circuit is configured to apply a voltage pulse having a pulse voltage to the piezoelectric transducer that induces a response signal, and capture peak positive and negative voltages of the response signal. The controller calculates a current condition value of the piezoelectric transducer based on the peak positive voltage, the peak negative voltage and the pulse voltage, and generates a diagnostic test result based on a comparison of the current condition value to a reference condition value corresponding to a properly operating piezoelectric transducer. The communications circuit communicates the process variable and the diagnostic test result to an external control unit over a process control loop.

    Abstract: An industrial process temperature transmitter for measuring a temperature of a process medium includes a temperature sensing unit, a compensation circuit, an output circuit and a housing. The temperature sensing unit includes a process temperature sensor and a secondary temperature sensor. A temperature signal that is indicative of the temperature of the process medium is produced based on a process temperature signal output from the process temperature sensor and a secondary temperature signal output from the secondary temperature sensor. The compensation circuit compensates the temperature signal for a response time of the temperature measurement to a change in the temperature of the process medium, and outputs a compensated temperature signal. The output circuit produces a temperature output as a function of the compensated temperature signal. The housing is attached to an exterior of the process vessel and contains the secondary temperature sensor.
