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: 9316543Abstract: A process sensor assembly comprises a hollow protective housing, a temperature sensor, a process transmitter, and a transient protector. The temperature sensor includes a probe extending out of the hollow protective housing to a sensing location, and a top plate movably secured to the hollow protective housing so as to allow travel within the hollow protective housing with vibrations of the probe. The process transmitter is configured to process and transmit sensor signals from the temperature sensor, and is retained on the top plate to move with the temperature sensor within the hollow protective housing. The transient protector is configured to condition power for to the process transmitter, and is anchored to the process transmitter so as to move with the process transmitter within the hollow protective housing.Type: GrantFiled: March 14, 2013Date of Patent: April 19, 2016Assignee: Rosemount Inc.Inventors: Andrew James Bronczyk, Aaron Andrew Perrault, Frank L.
