SG Series strain gauge Datasheet(1)

The sensitive zone of the sensor is designed to be glued to or embedded into the deforming substrate.
LEAP recommend testing the substrate adhesion/encapsulation prior to using the sensors.
• Most thermoplastics, we recommend testing Wacker G790 primer together with Wacker E43 adhesive.
• Natural rubber-based substrates, we recommend just Wacker E43.
• For textiles, the application of adhesive is just as important to consider, as the adhesive it’s self in order
to get best results. Thorough testing is recommended.
LEAP can also supply material samples for adhesion testing if required and can also carry out adhesive
testing services upon request.
In cases where overmoulding or other forms of encapsulation are desired, exposure to high temperature,
pressure and the use of solvents can damage the sensor. We recommend dialogue with LEAP, together
with experimentation with respect to techniques, materials and process conditions.
Standard LEAP gauges return area strain, though the substrate may strain in any predominant
direction.
