Combined material thermal expansion coefficient measuring device

The utility model relates to a material thermal expansion capability test technical field specifically provides a combined material thermal expansion coefficient measuring device. The pressure sensorthat combined material thermal expansion coefficient measuring device includes the temperature -controlled box body and is used for converting the deformation volume of the material that awaits measuring into pressure variation, the internal support that is provided with two along the horizontal direction interval arrangement of temperature -controlled box, the support has the horizontal support face that is used for the sample that awaits measuring that the support level placed, force transducer sets up to sentence at the horizontal support face and corresponds with the terminal surface thatsupports the sample that awaits measuring on the horizontal support face. Carrying out the support that supports at the internal sample of placing the level that awaits measuring that is provided withof temperature -controlled
