The Strain Monitor KL 66 is threaded on the structure to be surveyed and allows a precise and reproducible measurement of its stress changes. Using DIGI SENS vibrating wire technology instead of the strain gauge means having a simple mechanical mounting combined with a very accurate measurement. This technology also offers an extremely high resolution. Deformations of fractions of μm can be measured. Since the KL 66 is adapted to the material of the structure to be surveyed, differential thermal expansion has no negative influence on the precision. The DIGI SENS technology is also standing for a very good long-term stability. Since no organic material is involved in the measurement chain, creeping or other influence are reduced to the minimum. The KL 66 delivers a 5 V TTL frequency signal, proportional to the displacement measured. The frequency is a square root ment. In most applications it can be considered linear. This frequency signal is easy to transmit, immune to perturbations and can be treated directly by any processor.

The Strain Monitor KL 66 is delivered with all fixing parts needed. This allows a simple mounting on the desired structure. No special tooling is need- ed. No surface conditioning, no glues drying in clean room condition. No maintenance is needed. Just tighten the screw and you are ready to measure.
