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 remote seal assembly for a process transmitter includes a seal body containing a cavity sealed by a diaphragm. The seal body configured to be mounted to a process element containing a process fluid such that a first side of the diaphragm is exposed to the process fluid. A capillary contains a fill fluid that is in fluid communication with the cavity and a second side of the diaphragm. A coupling has a capillary recess and two cavities separated by a second diaphragm. The capillary extends through the capillary recess and connects to the coupling such that the fill fluid in the capillary is in fluid communication with one of the two cavities and the second diaphragm. A thermally conductive element preferably extends continuously along the capillary from the seal body toward the coupling and into the capillary recess without contacting the coupling.

Abstract: A pressure sensor includes a base having a high-pressure contact portion, and a diaphragm positioned over the base and having an external top surface opposite the base. The external top surface is defined within a closed perimeter and external side surfaces extend down from an entirety of the closed perimeter toward the base. A high-pressure contact portion of the diaphragm is aligned with and separated by a gap from the high-pressure contact portion of the base. A sensing element is coupled to the diaphragm and provides an output based on changes to the diaphragm. When a hydrostatic pressure load above a threshold value is applied to the entire external top surface and external side surfaces of the diaphragm, the hydrostatic pressure load causes the high-pressure contact portion of the diaphragm to contact the high-pressure contact portion of the base.

Abstract: A process fluid temperature calculation system includes a first temperature sensor disposed to measure an external temperature of a process fluid conduit. The process fluid temperature calculation system has a stem portion having a known thermal impedance. A second temperature sensor is spaced from the first temperature sensor by the stem portion. Measurement circuitry is coupled to the first and second temperature sensors. A microprocessor is coupled to the measurement circuitry to receive temperature information from the measurement circuitry and to provide an estimate of temperature of process fluid within the process fluid conduit using a heat flux calculation.

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 monitor module for a turbine flow meter includes a receiver that receives a sequence of pulses sent by the turbine flow meter. A frequency identifier identifies a frequency of the pulses in the sequence of pulses and a mean identifier identifies a mean frequency of frequencies of pulses. An alert system uses the mean frequency to determine when an alert should be issued.

Abstract: A single plate capacitance sensor includes a sensor capacitor and a reference capacitor that share common plate. A capacitance-to-digital sigma delta modulator provides separate sensor excitation and reference excitation signals to the sensor capacitor and the reference capacitor to provide high resolution detection. Programmable ratio-metric excitation voltages and adaptive excitation voltage sources can be used to enhance modulator performance.
