Patent number: 9335197Abstract: A retractable assembly, comprising: a housing; an immersion tube, which is axially movable between a service position and a process position. A first inlet facing away from the medium and a second inlet facing the medium. The immersion tube is moved from the service position to the process position by supplying the first inlet with energy, and the immersion tube is moved from the process position to the service position by supplying the second inlet with energy. A first mechanical blocking member shifts against a spring bias, and the blocking member engages in a first groove on the immersion tube. The first groove is located in the movement direction. The spring bias is so embodied that supplying the second inlet with energy releases the blocking member from the groove, whereby movement of the immersion tube from process position to service position becomes possible.Type: GrantFiled: May 2, 2013Date of Patent: May 10, 2016Assignee: ENDRESS & HAUSER CONDUCTA GESELLSCHAFT FÜR MESS-UND REGELTECHNIK MBH+ CO.
