Strain sensors

Piezoelectric strain sensors from Kistler are used for high-resolution measurements of strains occurring on a structure.

Piezoelelectric strain sensors from Kistler can be used for high-resolution measurements of the strains occurring on a structure. To achieve this, the sensor is mounted in a suitable position. If an indirect force measurement is required, the sensor is calibrated. The relevant factors here are the geometry of the structure, the material's modulus of elasticity and the mechanical stress. Surface strain sensors are attached to the structure with the mounting screw. The structure's strain is transmitted to the measuring element through static friction. Strain measuring pins need a cylindrical mounting bore in which the strain sensor is then inserted and preloaded. Kistler offers piezoelectric strain measurement sensors with axial and radial alignment to the axis of the bore hole.

Frequently asked questions

What are the differences between piezoelectric and strain gauge sensors for measuring strain?
Piezoelectric sensors are extremely sensitive, measure highly dynamic and virtually without any displacement needed. This makes it possible to cover large measuring ranges with a single sensor and also to measure strains on mechanical structures with high rigidity. Strain gauges, on the other hand, require at least a small deformation and are usually designed for a very specific force measurement range.
How do I choose the right strain sensor for my specific application?
Consider factors such as measurement range, sensitivity, accuracy, and environmental conditions when selecting a strain sensor. Our experts can help you select the best sensor for your needs.
How do I properly install a strain sensor?
Strain sensors are mostly used for indirect monitoring applications. They can be mounted either on the surface or as a pin in the material. In either case, it should be ensured that there is a mechanical stress in the material at the mounting location that is directly related to the relevant process that is to be monitored. Detailed information on mounting and calibration is sensor-specific and can be found in the data sheet.
