Abstract:

The invention generally relates to methods and devices for installing in a tubular shaft multiple strain gages, and more particularly to a method and a device for pneumatically forcing strain gages into seated engagement with the internal surfaces of a tubular shaft in an installation of multiple strain gages in a tubular shaft. The essence of the invention involves the novel concept of seating strain gages or other electronic devices in a template-like component, wrapping the template-like component about a pneumatically expansible body, inserting the component into a shaft and expanding the body pneumatically, a suitable adhesive having been applied to the surfaces.
