    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 steam quality meter includes a pipe with an inlet and an outlet. A rod is located within the pipe between the inlet and the outlet. The rod defines an annular flow passage between an outer wall of the rod and an inner wall of the pipe. A mixing device is located within the pipe between the inlet and an upstream end of the rod. Spaced sensors are located within the annular flow passage. Each sensor is configured to sense capacitance and/or impedance of steam flowing through the annular flow passage.

    Abstract: A magnetic flowmeter includes flowmeter electronics and a flowtube configured to receive process fluid flow. The flowtube has a plurality of electrodes disposed proximate an inner diameter to contact process fluid. At least one ultrasonic transducer is disposed within the flowtube and is configured to couple ultrasonic energy to the process fluid proximate at least one electrode. Flowmeter electronics are coupled to the plurality of electrodes and the at least one ultrasonic transducer and are configured to detect at least partial electrode coating or buildup and responsively generate a cleaning cycle within the flowtube using the at least one ultrasonic transducer.

    Abstract: A process variable transmitter for use in an industrial process includes a housing having a cavity formed therein. The housing has a barrier which divides the cavity into first and second cavities. Measurement circuitry in the first cavity is configured to measure a process variable of the industrial process. A terminal block assembly is located in the second circuitry. A moisture sensor has an electrical characteristic which changes based upon the presence of moisture in the second cavity.

    Abstract: A sensor includes a diaphragm having a bonding portion and a main boss separated from the bonding portion by at least one channel, the main boss having a first side face, a second side face and a chamfered corner face connecting the first side face to the second side face. A base of the sensor has a first contact area aligned with the main boss and separated from the main boss, wherein the bonding portion of the diaphragm is bonded to the base. At least one sensing element senses movement of the diaphragm.

    Abstract: A polymeric remote seal system is provided for coupling a single-use container to a pressure measurement instrument. The polymeric remote seal system includes a process-side coupling, an instrument-side coupling and a fluidic coupling therebetween. The process-side coupling is configured to couple to the single-use container and is formed of a radiation sterilizable polymer. The process-side coupling has a process-side deflectable diaphragm that is configured to deflect in response to pressure within the single-use container. The instrument-side coupling is configured to couple to the pressure measurement instrument and is formed of a radiation sterilizable polymer. The instrument-side coupling is configured to fluidically convey fluid pressure to an isolation diaphragm of the pressure measurement instrument. Tubing fluidically couples the process-side coupling to the instrument-side coupling.
