The press-on strain sensors measure the surface-strain directly at the mounting location, similar to bonded strain gauges. The strain gages are protected: they are positioned under the stainless protective foil and are strongly pressed onto the measu- ring surface that friction replaces the bonding normally used to fix strain gauges.

The sensors can be installed very easily and just in few seconds. The sensors do not need to be recalibrated every time they have been replaced or remounted.
