Abstract
The load cell disclosed is for detecting changes in tensile loading of a multiwire structural post-tensioning tendon for a concrete structure. The load cell has a pair of spaced end plates, an elastically deformable cylindrical steel member which extends between and is connected to the peripheral portions of the end plates, and a telemetric strain sensing device mounted between the end plates centrally within the cylinder. The cylindrical steel member carries the full load of the post-tensioning tendon, and because of the central location of the strain sensing device within the cylinder member, measurements will not be affected by eccentricity.
