Patent ID: 7918034

Claim:
Measuring device for measuring the length of elongate profiles ( 100 , 101 , 102 , 103 ) arranged in a longitudinal direction, in particular pipes, between at least two measuring legs ( 2 , 3 ) located opposite one another, at least one of which can be displaced in the longitudinal direction (L) until the two ends ( 110 , 111 , 112 , 113 , 120 , 121 , 122 , 123 ) of the elongate profile ( 100 , 101 , 102 , 103 ) make contact with a respective measuring leg ( 2 , 3 ), and at least one of the measuring legs ( 2 , 3 ) has at least one measuring ram ( 10 , 11 , 12 , 13 ) with in each case at least two webs ( 51 a , 51 b , 52 a , 52 b ) which run transversely to the longitudinal direction (L) and which can be moved elastically back and forth in the longitudinal direction (L) at a distance from one another, each web having a first end and a second end, the first end of which is in each case connected to a spacer section ( 80 ) which is arranged in a positionally stable manner relative to a measuring leg ( 3 ) during the length measurement, and the second end of which is in each case connected to a spacer section ( 81 , 82 ) which can be moved in the longitudinal direction (L) relative to a measuring leg ( 3 ) during the length measurement by means of a pressure force exerted by the elongate profiles ( 100 , 101 , 102 , 102 ) on a rigidly connected contact tongue ( 15 , 16 , 17 , 18 ), and comprising in each case a sensor ( 70 , 71 , 72 , 73 ) which is assigned to the measuring ram ( 10 , 11 , 12 , 13 ) and which measures the change in position of at least parts of the measuring ram ( 10 , 11 , 12 , 13 ) brought about by the elastic deformation.
