Problems solved by technology

The problem is that a laterally arranged field-limited contactless sensor produces a field that is too spatially extended for the required measurement area.
However, this results in a greater construction expense and thus an increase in costs
Another problem with sensors arranged in landscape orientation is the high space requirement in portrait orientation

Embodiment Construction

[0033] figure 1 A device known in the prior art for determining the distance and / or position of the measuring object 1 in a non-contact manner is shown. The measuring object 1 is made of a conductive material and is arranged on a positioning element 2, such as a valve stem. The positioning element 2 and therefore the measuring object 1 can be moved along the arrow shown in the figure. The sensor 3 is arranged on one side of the positioning element 2 and measures the distance of the measuring object 1 in a non-contact manner. To this end, the sensor 3 includes a measuring device 4 and / or a measuring element 5 configured as a coil.

[0034] figure 2 An exemplary embodiment of the device according to the invention is shown in a schematic cross-sectional side view, said device comprising a sensor 3 according to the invention. The measuring object 1 is arranged on the positioning element 2 and moves in the axial direction together with the positioning element 2. The base plate 6 i...

Abstract

The invention relates to a device for contactless distance and / or position determination of a measurement object (1), comprising an electrically conductive measurement object (1) and a sensor (3) which is operated in particular according to the inductive, capacitive or eddy current principle, the sensor (3) comprising a measuring device (4). The invention is characterized in that the measuring device (4) is formed by at least two spatially separated measurement elements (5, 5', 5''). The invention further relates to a corresponding sensor (3).

Description

Technical field [0001] The present invention relates to a device for determining the distance and / or position of a measurement object in a non-contact manner. The device has a conductive measurement object and a sensor, the sensor particularly operating according to the principle of induction, capacitance or eddy current, wherein the sensor Includes measuring device. Furthermore, the invention relates to a corresponding sensor. Background technique [0002] The positioning element (actor) of the path / position is often operated in a closed-loop control circuit. To achieve this, a sensor is needed to detect the positioning path (or distance / position / deflection). For this reason, there are many measurement methods (optical, electromagnetic, tactile) that represent the prior art. [0003] Many applications are based on the task of building as compact a motion device / sensor system as possible. In fact, the shaping of the configuration shape usually causes the axial movement of the c...
