A device for measuring compressive forces

摘要

A device for measuring compressive forces, comprising an annular body (1) having a pair of opposite, force-receiving front surfaces (2, 3) which are perpendicular to the central principal axis (4) of the body, and an annular cavity (5) essentially concentric with the principal axis and receiving a sensor means (6) for delivery of an electrical signal representing the force influence. The sensor means (6) comprises a sensor element (9) placed on the radially inner surface (7) of the cavity (5), said surface being situated at a distance from the principal axis (4) essentially corresponding to the radius (rR) for moment equilibrium for that part of the ring body (1) which receives a load.
