Abstract
The invention relates to a weight sensor comprising strain gauges which are deposited in thick films on a support (2). The support is made from an electrically-insulating material which is intended to be applied to a metallic body (1) that is essentially subject to bending. According to the invention, the support (2) comprises a ceramic material which has a Young's modulus E2 that is equal to or less than that E1 of the biased metallic body (1) and which is applied to the latter by means of gluing.
Claims18
Weight sensor with strain gauges deposited in a thick film on a support (2) of an electrically insulating material intended to be applied to a metal body (2) deformable primarily in flexure, characterized in that said support (2) is of a ceramic material having a Young's modulus E2 equal to or lower than that E1 of the deformable metal body (1) and that it is applied by adhering to the latter.
Weight sensor comprising:
- a support of an electrically insulating material;
- strain gauges deposited in a thick film on said support;
- and a metal body deformable primarily in flexure, wherein:
- said metal body has a Young's modulus E1, said support is of a ceramic material having a Young's modulus E2, E2 is equal to or lower than that E1, and said support is applied to said metal body by adhering thereto.
