Patent number: 9194685Abstract: A retractable assembly for immersion-, flow- and annex-measuring systems in analytical process technology for measuring at least one measured variable of a medium in a process containment, comprising an essentially cylindrical housing having a housing interior; an immersion tube, which is axially movable between a retracted service position in the housing and a process position extended from the housing. In the service position, the immersion tube is positioned in the housing interior; a closure element on an end region of the immersion tube facing the medium for sealing off the housing interior from the process containment when the immersion tube is located in the service position, and a proximity detector in or on the end region of the housing facing the medium for detecting the closure element in the service position.Type: GrantFiled: May 21, 2013Date of Patent: November 24, 2015Assignee: Endress + Hauser Conducta Gesellschaft für Mess- und Regeltechnik mbH + Co. KGInventors: Rainer Schlereth, Stefan Robl, Alejandro Vaca Torres, Martin Lohmann

Patent number: 9091570Abstract: A retractable assembly, comprising: a housing; a media connection with complementary connecting means; an immersion tube; and a probe provided in the immersion tube. The probe has a probe head on its end facing the medium, wherein, in the service position, the probe head is arranged within a treatment chamber formed in the housing, wherein the immersion tube is divided into three regions, and, indeed, a upper region facing away from the containment, a middle region, on which a sealing system is provided, and a lower region facing the containment, wherein the sealing system is so embodied that in no position of the immersion tube does an exchange of medium or impurities from the drive to the treatment chamber, or vice versa, occur.Type: GrantFiled: August 7, 2012Date of Patent: July 28, 2015Assignee: ENDRESS + HAUSER CONDUCTA GESELLSCHAFT FUR MES- UND REGELTECHNIK MBH + CO.

Patent number: 8621947Abstract: An assembly device, especially a retractable assembly, for a measuring probe for measuring process variables in a process, comprising: an assembly housing with a connection system for connecting the assembly device to a process container; a tubular holder for a measuring probe, wherein the tubular holder is guided in the assembly housing axially displaceably between a measuring position in the process container and a maintenance position outside of the process container; and a damping system to damp axial shifting of the tubular holder. The damping system comprises a fluid filled, damping cylinder within the assembly housing, and a damping piston unit guided within the damping cylinder (15) in operative connection with the tubular holder.Type: GrantFiled: March 30, 2010Date of Patent: January 7, 2014Assignee: Endress + Hauser Conducta Gesellschaft für Mess—und Regeltechnik mbH + Co.
