Device for positive pressure detection in operating volume of robotic gripper in e.g. industrial processing field, has wall portion with unit, which experiences deformation that is irreversible in course of intended use of actuator

摘要

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. 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.
