The KDB special force transducer has been designed to comply with the requirements of EN 12390. This standard describes the procedure for verifying testing machines for building materials. In accordance with the standard, two hardened plates for load application are included in the force sensor’s scope of supply. Centering pins facilitate assembly.
Four independent strain gauge full bridges enable bending moments to be measured alongside the total force.
In case of centered load application, the force sensor can be used up to 3 MN. HBM offers a spherical load application element and a thrust piece for this application. This enables the KDB to be used as a reference transducer compliant with Class 0.5 requirements of ISO376.
