Abstract: A pressure transmitter assembly for measuring a process pressure of an industrial process includes a pressure sensor configured to sense the process pressure. A process coupling couples the pressure sensor to the industrial process. In one example configuration, a phase change material carried in the process coupling is configured to reduce heat transfer from the industrial process to the process variable sensor by changing phase in response to heat from the industrial process. In another example configuration, a thermocouple electric cooling element is coupled to the process coupling and configured to conduct heat away from the coupling in response to an applied electric current.

Abstract: A magnetic flowmeter comprises a pipe section for process flow, a coil for generating a magnetic field across the pipe section, a current source for energizing the coil to generate the magnetic field at a coil drive frequency, and electrodes for sensing voltage induced across the process flow by the magnetic field. A processor calculates a function of the sensed voltage and generates a flow output based on the function. The processor adjusts an operating parameter of the flowmeter, such as electrode voltage sampling period, the coil drive frequency, or a phase shift, as a function of a sensed electrode-to-electrode or electrode-to-ground complex impedance.

Abstract: A gauge system comprises a sensor that produces a sensor signal as a function of a sensed parameter. The gauge system also comprises a motor and a gauge having a scale and a movable indication needle that is driven by the motor and displays a measurement value of the sensed parameter based upon position of the needle relative to the scale. The gauge system further includes a position sensor that produces a position feedback signal representative of a sensed position of the needle and a controller that provides drive commands to the motor based on the sensor signal and the position feedback signal.

Abstract: A magnetic flowmeter includes at least one coil configured to generate a magnetic field within a process fluid flow. A pair of electrodes is configured to detect an electromotive force within the flowing process fluid in response to the magnetic field. Measurement circuitry is coupled to the pair of electrodes and is configured to provide an indication of the detected electromotive force. A processor is coupled to the measurement circuitry and configured to receive the indication of the detected electromotive force and determine a flow-related output based on the detected electromotive force. A diagnostics component is configured to analyze a number of successive parameters of the magnetic flowmeter in order to provide an indication of a detected entrained fluid.

Abstract: A non-intrusive sensor system includes an array of sensors disposed in a process to measure various input process phenomena and a logic unit that analyses the sensor measurements using an empirical model to produce an estimate of a further process phenomenon not measured directly by any of the array of sensors. The sensors within the array of sensors may be non-intrusive sensors that measure input process phenomena in an intrusive or non-intrusive manner but are non-intrusive with respect to the output process phenomenon as none of these sensors comes into direct contact with the process fluid or process element exhibiting the output process phenomenon. The sensors within the array of sensors can be any type of sensors that produce a measurement of a particular process phenomenon at the same or at different locations within a process.
