Description
The LKAF is a flat round compression load cell of stainless steel for nominal loads from 250 kg to 100 t. It is the close relative of the LKAD and shares its build, its nominal output of 2 mV/V and its sealing, but the manufacturer states no OIML class for it and instead gives one set of tight limits that holds over the whole range: combined error and zero return within ± 0.03 %, non repeatability within ± 0.01 %. Input and output resistance are 700 Ω, the cell carries 120 % of its nominal load in service and breaks above 300 %, and the body is sealed to IP68, tested for 100 hours under a metre of water. The output is five metres of shielded PVC cable, ten on request. A loading head is offered for each load group, and the LMAAA weighing unit turns the cell into a complete support.
