US 2014/0165751 A1 · POSITIONING DEVICE AND MEASURING DEVICE

Abstract

A positioning for positioning a measuring element (2) and a measuring device with such a positioning device have an object of providing a positioning device for positioning a measuring element or a measuring device with a measuring element and a positioning device that is a simplification compared to the prior art and that meets the requirements for positioning with respect to accuracy and reproducibility. The object is met in the positioning device in that three wheels are provided (3, 4, 5), which are designed as a ring gear (3), a sun and a planetary gear (5). The ring has an interior space (6) in which the sun and the planetary are arranged. Furthermore, the planetary is engaged with the sun and with the ring gear (3).

Positioning device for positioning a measuring element, comprising:

three wheels, a first of the three wheels being a ring gear with an interior space and a center axis, a second of the three wheels being a sun gear with a center axis, and a third of the three wheels being a planetary gear,
wherein the sun gear and the planetary gear are arranged at least partially in the interior space of the ring gear, and
wherein the ring gear, the sun gear and the planetary gear arranged and adapted in relation to one another in such a manner that the planetary gear is engaged with the sun gear and with the ring gear.

Measuring device, comprising:

at least one measuring element for at least one of determining and monitoring a process variable and
a positioning device for positioning the measuring element having three wheels, a first of the three wheels being a ring gear with an interior space and a center axis, a second of the three wheels being a sun gear with a center axis, and a third of the three wheels being a planetary gear,
wherein the sun gear and the planetary gear are arranged at least partially in the interior space of the ring gear,
wherein the ring gear, the sun gear and the planetary gear arranged and adapted in relation to one another in such a manner that the planetary gear is engaged with the sun gear and with the ring gear, and
wherein the planetary gear and the measuring element are connected to one another in such a manner that the planetary gear moves the at least one measuring element.
