Patent number: 11041743Abstract: The present disclosure relates to a field device of automation technology, comprising a housing and a sensor unit sensitive for a process variable of a medium. The housing has a passageway to accommodate the sensor unit and the sensor unit protrudes from the housing through a terminal opening of the passageway. A clamping angle and a screw are introduced into the housing in a region of the housing adjoining the opening of the passageway. By means of the screw the clamping angle is shiftable in the housing a predeterminable distance in the direction of the sensor unit, and the clamping angle shifted in the direction of the sensor unit is embodied to press with a first clamping angle section of the clamping angle radially on a clamping region of the sensor unit arranged in the housing and facing the opening of the passageway.Type: GrantFiled: March 12, 2018Date of Patent: June 22, 2021Assignee: Endress+Hauser SE+Co. KGInventors: Michael Lais, Raphael Schonhardt

Patent number: 11044826Abstract: The present disclosure relates to a cover-securing mechanism for a transmitter housing closed by a screwed-on cover. The cover-securing mechanism includes a securement pin with a screw arranged at a first end region of the securement pin. A passageway, which is embodied to accommodate the securement pin, is integrated in the cover. A groove includes a circularly shaped section and is introduced into a cover facing region of the transmitter housing. The securement pin is securable at a transmitter housing far end of the cover in the passageway such that in a secured state a second end region of the securement pin protrudes inwardly into the groove and, as such, a twisting of the cover screwed onto the transmitter housing is constrained relative to the transmitter housing.Type: GrantFiled: December 1, 2017Date of Patent: June 22, 2021Assignee: Endress+Hauser SE+Co.

Patent number: 10168240Abstract: A measuring transducer for metrological registering of a pressure to be measured as relative pressure referenced to a reference pressure reigning in the environment of the measuring transducer, comprising: a housing; a relative pressure sensor arranged in the housing; a pressure supply, via which the pressure to be measured is fed to the relative pressure sensor, and a reference pressure supply, via which the reference pressure is fed to the relative pressure sensor. An entrance of and to the reference pressure supply communicates with an opening in a housing outer wall, on whose exterior the reference pressure acts, characterized in that a pressure equalizing element is applied in the entrance of the reference pressure supply, and the pressure equalizing element has a securement element, a filter element and a protective cap.Type: GrantFiled: April 20, 2015Date of Patent: January 1, 2019Assignee: ENDRESS+HAUSER SE+CO.KGInventors: Raphael Schonhardt, Michael Lais
