1. A device for measuring diameters of large cylindrical surfaces in the form of a body with a sensor and contact elements, characterised by that the body (1) in the form of a plate near rectangle shape has brackets (2) in each corner area, which determine the plane of the contact elements (3), while in the areas close to the brackets (2) it has preferably pass-through seats (6) and a centrally located seat (4) mounted in the upper plate (7) of both the sensor (5) and mandrels (9), while the body (1) with the upper plate (7) is connected kinematically through elastic elements (10).
