SENSY force and static torque transducers measure with strain gauge bridges the deformation of metal body caused by application of mechanical stresses.

This mechanical stress may not exceed the elastic limit of the material without damaging or destroying the sensor.

However, even with overloads within the elastic limit of the material, alteration of the proof body will occur if these overloads are applied repeatedly.

This deformation, which is initially very small, can ultimately lead to sensor failure.

This fatigue resistance is characterized by a guaranteed number of cycles. It depends on the material, the stress rate (μm/m) and whether this constraint is uni- or bidirectional.

For SENSY steel sensors, the fatigue strength is as follows:

Caution: This is not valid for certain types of sensors for which the maximum stress is not located where the strain gauges are bonded.
(eg : membrane sensors).
