Abstract: A wet chemistry analyzer is provided. The wet chemistry analyzer comprises a reaction chamber configured to receive a reactant solution from a sample inlet and facilitate a process reaction. The wet chemistry analyzer also includes a detection chamber configured to receive a portion of a reaction mixture from the reaction chamber and measure a concentration of a chemical within the reaction mixture. The reaction chamber and the detection chamber are fluidically coupleable such that a portion of the reaction mixture can be directed to flow into the detection chamber to pre-condition a surface inside the detection chamber.

Abstract: A process fluid pressure transmitter is provided. The process fluid pressure transmitter includes a pressure sensor having an electrical characteristic that changes in response to a deformation of the pressure sensor in response to pressure. Measurement circuitry is coupled to the pressure sensor and is configured to provide an indication of the electrical characteristic. An isolation diaphragm is configured to contact the process fluid and deform in response to process fluid pressure. A substantially incompressible fill fluid fluidically couples the isolation diaphragm to the pressure sensor. An overpressure compliant structure is coupled to the fill fluid and is configured to be substantially rigid at pressures below a selected threshold, but to deform in response to pressure above the selected threshold.

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. Preferably, measurement circuitry in the first cavity is configured to measure a process variable of the industrial process. A terminal block assembly is positioned in the second cavity. The terminal block assembly forms a seal with the housing thereby forming a third cavity between the barrier and a circuit board of the terminal block assembly.

Abstract: A process variable transmitter for use in an industrial control or monitoring process is provided and includes a housing with a cavity formed therein which extends between first and second housing openings. The transmitter further includes a process variable sensor configured to sense a process variable of the industrial process. An electronics carrier assembly is mounted in the cavity and is configured to define a first compartment and a second compartment in the cavity and provide a seal therebetween. Measurement circuitry is carried by the electronics carrier assembly in the first compartment and configured to receive a process variable signal and provide an output. An electrical connection is carried on the electronics carrier assembly in the second compartment and is electrically coupled to the output of the measurement circuitry.

Abstract: A corrosion rate measurement system includes a first membrane of a first material configured to be exposed to a corrosive material and deflect in response to corrosion. A second membrane is configured to be exposed to a corrosive material and deflect in response to corrosion. A pressure sensor is operably coupled to at least one of the first and second membranes and configured to measure deflection of at least one of the first and second membranes as a function of a pressure and an amount of corrosion at least one of the first and second membranes.

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.
