Vorrichtung und Verfahren zur Ueberdruckdetektion in einem Arbeitsvolumen eines Aktors

DE 102008026534 A1 UPAB: 20100101 NOVELTY - The device has a wall portion partially limiting an operating volume (1) or a volume fluidically coupled to the operating volume. The wall portion includes a unit i.e. positive pressure detector, which experiences deformation that is irreversible in the course of an intended use of an actuator during application of pressure by a working medium e.g. liquid, with exceedance of predetermined maximum pressure. The unit is designed in the form of a predetermined breaking point, a diaphragm or a deformable diaphragm wall (9). The unit and the actuator are connected as a single piece. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for positive pressure detection in an operating volume filled by a working medium and provided of an actuator. USE - Device for positive pressure detection in an operating volume of an actuator i.e. robotic gripper, in industrial processing and manufacturing fields. ADVANTAGE - The unit experiences the deformation that is irreversible in the course of the intended use of the actuator during the application of pressure by the working medium with exceedance of the predetermined maximum pressure, thus reducing a number of components for configuring the device, and hence realizing a simple and inexpensive device. The device can be attached to the actuator in a tamper-proof and inseparable manner
