Patent number: 10663931Abstract: A process variable transmitter for use in an industrial control or monitoring process is provided and includes a housing with a cavity formed therein. The housing includes an integrated terminal block which defines first and second compartments in the cavity. The transmitter further includes a process variable sensor configured to sense a process variable of the industrial process. Measurement circuitry is carried in the first compartment and configured to receive a process variable signal from the process variable sensor and provide an output. An electrical connection is carried on the integrated terminal block in the second compartment and is electrically coupled to the output of the measurement circuitry.Type: GrantFiled: September 24, 2013Date of Patent: May 26, 2020Assignee: Rosemount Inc.Inventors: Aaron Andrew Perrault, Dirk Willy Bauschke, Loren Michael Engelstad

Patent number: 9602122Abstract: 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.Type: GrantFiled: September 28, 2012Date of Patent: March 21, 2017Assignee: Rosemount Inc.Inventors: Jason Harold Rud, Loren Michael Engelstad
