Abstract: A device for holding a transmitter and a receiver for detecting a deformation state of a component. The device includes a first holding part and a first receptacle, the transmitter being disposed on the first holding part via the first receptacle, wherein the first receptacle and the first holding part, together with the component, form at least one of a first connecting element, a first clamp, a first positive fit joint, a first glued joint, and a first welded joint. The device also includes a second holding part and a second receptacle, the receiver being disposed on the second holding part using the via receptacle, wherein the second receptacle and the second holding part, together with the component, form at least one of a second connecting element, a second clamp, a second positive fit joint, a second glued joint, and a second welded joint.

Abstract: The invention concerns a device for retaining a motion sensor consisting of a transmitter (2) and a receiver (3). The transmitter (2) and the receiver (3) are form-closed on the structural element (1) respectively by means of a housing (20, 30) and a retaining element (21) corresponding to the housing (20, 30) and connected thereto by a screw connection (22). Therefor, the housing (20, 30) and the retaining element (21) form a clamping connection with the structural element (1), the housing (20, 30) comprising a clamping element (23) in operative connection with the structural element (1).

Abstract: A device for detecting different conditions of a component, such as distorted conditions, movements and loaded conditions. Said device comprises a transmitter and a receiver which are located independently on at least one component at a distance from one another and an evaluation unit. The transmitter emits an electromagnetic wave (such as e.g. a laser beam), or a focused particle beam to the receiver. The spatial resolution can be increased by multiple reflections from a mirror and a semi-transparent mirror.
