20110107857 | Probe system for measuring a measured variable of fluid contained in a process container, especially for sterile applications - A probe system for measuring a measured variable of a fluid, especially a liquid, contained in a process container comprising: A probe body, which is connectable to the process container by means of a process connection; axially shiftable in a guiding passageway of the probe body between a measuring position and at least two different treatment positions, an immersion tube, which has a protective cylinder on its front end immersible in the fluid; held in the immersion tube, a measuring probe having a measuring head, wherein the measuring head is arranged within a region of the protective cylinder having openings; a first treatment chamber formed between the guiding passageway and the immersion tube; a second treatment chamber formed between the guiding passageway and the immersion tube and adjoining the first treatment chamber on a side of the first treatment chamber facing away from the process connection; and a seal arranged between the first and second treatment chambers, wherein the immersion tube has a first section with a first outer diameter and a second section adjoining the first section and having a second outer diameter smaller than the first outer diameter, so that, through axial shifting of the immersion tube, the seal arranged between the first and second treatment chambers can be opened. | 05-12-2011 |
20110303006 | RETRACTABLE ASSEMBLY FOR A SENSOR - A retractable assembly for a sensor, which determines a physical and/or chemical, process variable in a process medium. The retractable assembly has a housing, in which a tubular holder for accommodating the sensor is arranged such that it can be moved linearly by a drive unit. At least one cascaded cylinder is provided for the linear shifting of the tubular holder, wherein the cascaded cylinder comprises at least two cylinders arranged one after the other in the direction of the stroke movement. Furthermore, the cascaded cylinder is, or the cascaded cylinders are, embodied and/or operable in such a manner that the sensor is movable into at least two different positions. | 12-15-2011 |
20120272756 | PROBE SYSTEM FOR MEASURING A MEASURED VARIABLE OF A PROCESS MEDIUM CONTAINED IN A PROCESS CONTAINER - A probe system, including: a connector apparatus; a treatment chamber part having at least one treatment medium supply line communicating with the treatment chamber; a measuring head seated so as to be axially shiftable, and a treatment position, wherein the immersion tube, on its connector apparatus-side front end, has a front-end closed, protective cylinder, and is arranged in a section of the immersion tube, so that, in the measuring position of the immersion tube, the measuring head is contactable via perforations with the process medium, and in the treatment position of the immersion tube, is contactable with the treatment medium; and a drive system for axial shifting of the immersion tube, arranged on the end region of the probe system facing away from the connector apparatus. The treatment chamber part is surrounded by a support structure connected with the connector apparatus and with the drive system. | 11-01-2012 |
20130036843 | Retractable Assembly - 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. | 02-14-2013 |
20130291633 | Retractable Assembly - 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. | 11-07-2013 |
20140298901 | RETRACTABLE ASSEMBLY FOR IMMERSION-, FLOW- AND ATTACHMENT- MEASURING SYSTEMS - A tool and a retractable assembly for measuring at least one measured variable of a medium in a containment, comprising: an essentially cylindrical housing; an immersion tube, which is movable axially in the housing between a service position run out from the medium and a process position run into the medium; and an engagement apparatus secured on the housing; wherein a movable piston is provided in the engagement apparatus and at least a first position and a second position of the piston are provided. The engagement apparatus holds the immersion tube in the service position when the piston is located in the first position, especially when no energy supply is present, and the engagement apparatus holds the immersion tube in an intermediate position between the service position and the process position and prevents further movement of the immersion tube in the direction of the medium when the piston is located in the second position. | 10-09-2014 |
20150097343 | Sealing System and Retractable Assembly Including Such - A retractable assembly and a sealing system, the sealing system comprising: an essentially hollow, cylindrical housing with an inner space and a peripheral groove open to the inner space in the housing. The peripheral groove defines a plane in the housing and the normal of the plane is parallel to the longitudinal axis of the housing. The groove includes at least one, preferably two, extension spaces expanding the groove. The extension space is arranged on the side of the groove facing away from the inner space. An annular seal corresponding to the groove is arranged in the groove. The annular seal is formed of at least a first section facing the inner space and a second section facing away from the inner space. | 04-09-2015 |
20150285663 | Retractable Assembly - A retractable assembly for immersion-, flow- or add-on measuring systems in analytical process technology for measuring at least one measured variable of a medium in a containment, comprising: an essentially cylindrical housing; an immersion tube, which is movable axially in the housing between a service position out of the medium and a process position in the medium; and a sensor for measuring the measured variable. The sensor is arranged in the immersion tube, wherein the sensor protrudes at least sectionally out of the immersion tube at the end of the immersion tube remote from the medium; and an openable and closable cover, which surrounds at least the section of the sensor protruding out of the immersion tube. The sensor in the opened state of the cover is mountable and demountable, respectively, in and from the immersion tube. The retractable assembly is characterized in that the cover at least sectionally travels with the movement of the immersion tube and in the process position is located at least sectionally in the housing. | 10-08-2015 |
