The relative permissible oscillatory stress specifies the stress up to which the transducer is fatigue resistant. This value is usually specified as a relative quantity based on the nominal (rated) force.
In general, the permissible oscillatory stress is given as a peak-to-peak value, i.e. the difference between the maximum and the minimum force. Force transducers may be stressed with this amplitude both dynamically and alternatingly.
Example: A tensile and compressive force transducer has a nominal (rated) force of 200 kN, the permissible oscillation width is 100%. In this case, the transducer may be loaded between 0 and 200 kN as well as between -100 kN and 100 kN.
