Abstract
The invention relates to a combination of a load cell (7) and a tubular insert (3) for mounting in a bore (2) in a machine component (1), wherein the load cell (7) is structurally connected to an inner sleeve (6), which is axially displaceable inside an outer sleeve (4), which is insertable in the bore (2), the inner and outer sleeves (6, 4) having portions with mutually tapering envelope surfaces facing each other, and a flange (5) being provided for displacing the inner sleeve (6) and the outer sleeve (4) axially relative to each other for expanding the outer sleeve (4) partially for increasing the grip between the insert (3) and the bore (2), thereby giving the load cell (7) a pretension sufficient for emitting signals representative for the load acting on the machine component (1).
