To calibrate a transducer you need a standard machine to load it. Depending on requirements and measuring range we recommend the following standard machines:

Lever and deadweight
A variable mass stack loads the transducer via a lever of a constant length.
Jockey weight
A constant mass movable on the lever loads the transducer via the lever.
Lever and force reference
A force, controlled by a force measuring system, loads the transducer via a lever of a constant length.
