Abstract: A process variable transmitter, includes an analog-to-digital (A/D) converter that receives a sensor signal provided by a sensor that senses a process variable and converts the sensor signal to a digital signal. A processor receives the digital signal and provides a measurement output indicative of the digital signal. A noise detector receives the sensor signal and generates a first value indicative of a number of positive noise events relative to a positive threshold value and a second value indicative of a number of negative noise events relative to a negative threshold value. The processor evaluates the noise count and generates a noise output, indicative of detected noise, based on the first and second values.

Abstract: A process fluid pressure sensing system includes a process fluid pressure transmitter and a process manifold. The process fluid pressure transmitter has first and second pressure inlets and is configured to obtain a measurement relative to pressures applied at the first and second pressure inlets and provide a process variable output based on the measurement. The process manifold is operably coupled to a process fluid and has first and second pressure outlets. A first high-pressure coupling joins the first pressure outlet of the process manifold to the first pressure inlet of the process fluid pressure transmitter. A second high-pressure coupling joins the second pressure outlet of the process manifold to the second pressure inlet of the process fluid pressure transmitter. The first and second high-pressure fluid couplings are configured to accommodate misalignment between the respective pressure outlets and inlets.

Abstract: A pressure transmitter has a pressure sensor, an isolator diaphragm, and a fill tube. Interior passages in the pressure sensor module body are filled with isolator fluid and provide fluid connections. The isolator fluid couples pressure from the first isolator diaphragm assembly to the pressure sensor. A first crimp portion of the fill tube radially narrows into a substantially solid circular cylindrical cross section to form a first primary seal that is resistant to high pressure cycling.

Abstract: A temperature measurement and control device for rotating heated rolls, such as those used in the fiber processing industry. The temperature sensor is stationarily mounted and positioned in a slot at one end of a rotating roll, and the sensor is used for controlling power to a heater utilized with the roll. The sensor thus is used to control the temperature of the roll surface. At high roll speeds the thermal coupling between the sensor and the roll is adequate, but at lower speeds that are encountered during the slowing down and stopping of the rolls, the thermal coupling between the roll surfaces and the sensor reduces in efficiency and the sensor conducts a large proportion of heat to its mounting structure. The present device utilizes passing a current through the sensor to self-heat the sensor to compensate for this decrease in thermal coupling and resultant stem conduction error.
