For calibration of strength measuring equipment, scales and weighing systems, standard weights for compensation or tensile calibration are available.
The combination of weights allows generating a known weight or strength in the system. In many cases we don’t need the pressure of the standard weights, there is no need to place weights or it is necessary to install the measurement element in the same system. For that, we have calibrated dynamometers that can be inserted in the system by measuring the process simultaneously.
These dynamometers can work tensile or compressive (some of them are bidirectional).
