The Strain Gages are used to measure the deformation of materials. These devices are widely used when the deformation of a structure is relevant such as the wings of a plane or the structure of telescopes or rockets.
The necessity of testing these strain gages at a wide temperature range leads to the necessity of coupling force-deformation equipment to climatic chambers.
This document describes how ALTER has done this to allow testing Strain Gages from -190ºC to more than 200ºC. The use of Strain Gages in space leads to the necessity of testing them in thermal vacuum conditions. A description of the setup developed by ALTER to do a life test with periodic application of strain in vacuum at a controllable temperature is also described.
