Abstract
A sensor unit for a fluidic cylinder having a base carrier on which a circumferential seal is formed, so that an interior of the fluidic cylinder is sealable, and having a position sensor for detecting a position of the piston, and having a pressure sensor for detecting a pressure in the interior.
Claims11
A sensor unit for a fluidic cylinder having a base carrier on which a circumferential seal is formed, so that an interior of the fluidic cylinder is sealable, and having a position sensor for detecting a position of a piston, wherein the sensor unit has a pressure sensor for detecting a pressure in the interior;
- and
- wherein a pressure-variable region is formed on a surface of the base carrier in the interior, and in that a pickup for detecting a pressure-dependent shape change of the pressure-variable region is arranged outside the interior.
A method for determining an operating state of a fluidic cylinder, wherein
- a position of a piston is detected by means of a position sensor, in that a pressure in an interior of the fluidic cylinder is detected by means of a pressure sensor, and in that the operating state is determined from the detected position and the detected pressure;
- and wherein the operating state is used to determine a weight load and/or a ground support.
A fluidic cylinder having a piston movable by fluid and having a position sensor for detecting a position of the piston, wherein
- the fluidic cylinder has a base carrier on which a circumferential seal is formed and a pressure sensor for detecting the pressure within the fluid;
- and
- wherein a pressure-variable region is formed on a surface of the base carrier in an interior of the fluidic cylinder, and a pickup for detecting a pressure-dependent shape change of the pressure-variable region is arranged outside the interior of the fluidic cylinder.
