Patent number: 11226242Abstract: An industrial process temperature transmitter for measuring a temperature of a process medium includes a temperature sensing unit, a compensation circuit, an output circuit and a housing. The temperature sensing unit includes a process temperature sensor and a secondary temperature sensor. A temperature signal that is indicative of the temperature of the process medium is produced based on a process temperature signal output from the process temperature sensor and a secondary temperature signal output from the secondary temperature sensor. The compensation circuit compensates the temperature signal for a response time of the temperature measurement to a change in the temperature of the process medium, and outputs a compensated temperature signal. The output circuit produces a temperature output as a function of the compensated temperature signal. The housing is attached to an exterior of the process vessel and contains the secondary temperature sensor.Type: GrantFiled: May 28, 2019Date of Patent: January 18, 2022Assignee: ROSEMOUNT INC.Inventors: Jason Harold Rud, Steve Richard Trimble

Publication number: 20180238741Abstract: An industrial process temperature transmitter for measuring a temperature of a process medium includes a temperature sensing unit, a compensation circuit, and an output circuit. The temperature sensing unit includes a process temperature sensor that is separated from the process medium by an isolation wall. The temperature sensing unit is configured to produce a temperature signal that is indicative of the temperature of the process medium based on a process temperature signal output from the process temperature sensor during a temperature measurement. The compensation circuit is configured to compensate the temperature signal for a response time of the temperature measurement to a change in the temperature of the process medium, and output a compensated temperature signal. The output circuit is configured to produce a temperature output as a function of the compensated temperature signal corresponding to the temperature of the process medium.Type: ApplicationFiled: February 21, 2017Publication date: August 23, 2018Inventors: Jason Harold Rud, Steve Richard Trimble

Patent number: 9157763Abstract: A process transmitter includes a sensor for producing an analog process signal as a function of a process parameter. The uncompensated analog process signal is digitized by an A/D converter and digitally compensated by a digital processor. The digitized signal from the analog-to-digital converter is also band pass filtered. The digitally compensated signal and the band pass filtered signal are combined to produce a transmitter output.Type: GrantFiled: February 6, 2008Date of Patent: October 13, 2015Assignee: ROSEMOUNT, INC.Inventors: John Paul Schulte, Steven Richard Trimble, Troy Michael Reller

Patent number: 7808379Abstract: A selectable mode field transmitter is configurable to operate in one of a plurality of operating modes having different combinations of function, performance, and power consumption. The selectable mode field transmitter includes a housing, a sensor located within the housing, and transmitter circuitry for transmitting data provided by the sensor to a receiver external to the housing. The transmitter circuitry includes a controller that electrically configures the transmitter circuitry to one of a plurality of operational modes in response to mode selection data received from a source external to the housing. Therefore, the selectable mode field transmitter can be configured based on the needs or requirements of a particular application.Type: GrantFiled: March 5, 2007Date of Patent: October 5, 2010Assignee: Rosemount Inc.Inventors: Robert C. Hedtke, John Paul Schulte, Steven Richard Trimble

Patent number: 5465243Abstract: The optical tape recorder of the present invention is capable of archiving data at rates in excess of 400 megabits per second by concurrently writing or reading a plurality data tracks in each data trace. A read-write module outputs an illumination beam comprised of combined multiple write beams (channels), a read beam and an autofocus beam. Optics within the read-write module spatially combine and accurately position the plurality of beams with respect to each other to form the multi-beam illumination beam. A read-write head comprised of a synchronized scanning transmissive polygon and rotating lens wheel scans the multi-beam illumination beam across a recording media to read or write multi-channel data tracks. An autofocus system is also included to ensure that the multi-beam illumination beam is accurately focused on the recording media.Type: GrantFiled: April 25, 1994Date of Patent: November 7, 1995Assignee: E-Systems, Inc.Inventors: John D. Boardman, Scott M. Hamilton, Mervin L. Gangstead, Jimmie L. Sadler, Richard A. Trimble, Jeffrey P. Welch

Patent number: 5023463Abstract: A photonic array bus provides a connectorless, computer backplane-like communication systems for advanced data processing and communications systems requiring operation rates exceeding 1 gigahertz. Components of a multiple component advanced data processing or communications system are coupled to pairs of laser transmitters and laser receivers. The laser transmitter and receiver pairs are arrayed in a coplanar circular fashion about a central disperser lens. A laser transmitter emits a laser beam incident on the central disperser lens. The central disperser lens disperses the laser beam into a coplanar array of laser beams illuminating the laser receivers. Multiple channel operation is achieved by "stacking" along the length of the disperser lens coplanar arrays of pairs of laser transmitters and receivers.Type: GrantFiled: March 15, 1990Date of Patent: June 11, 1991Assignee: E-Systems, Inc.Inventors: John D.
