Abstract: A preassembled strain gauge unit includes a housing having a resilient material therein. At least one strain sensing element is connected to the resilient material. Installation of the strain gauge unit is accomplished by applying adhesive to the strain sensing element and then fastening the housing to a surface with the adhesive between the surface and the strain sensing element. The resilient material is particularly designed to function as a spring during the adhesive curing period to apply a force to the strain sensing element during such adhesive curing period. In addition, the resilient material provides a seal for minimizing contact of moisture and air with the strain sensing element.
