A four element force sensor

 StrainBond™ is a unique service we offer. Our decades of technical expertise with photoelastic coatings and two-dimensional models enable visualization of actual strain patterns and gradients in structures. This offers tremendous time-saving and cost-effective benefits when choosing strain gage locations, gage size and optimal pattern.

The StrainBond™ technology also reveals the kind of structural modifications that can be made to optimize performance, either as a transducer or as a structural member. Areas of excess material or stress concentrations are often easily seen using the StrainBond™ photoelastic technique.
