The invention relates to a weight sensor comprising strain gauges which are deposited in thick films on a support (). The support is made from an electrically-insulating material which is intended to be applied to a metallic body () that is essentially subject to bending. According to the invention, the support () comprises a ceramic material which has a Young's modulus Ethat is equal to or less than that Eof the biased metallic body () and which is applied to the latter by means of gluing.

Weight sensor

A force-measuring apparatus is provided having a first plate, a second plate disposed above the first plate and spaced apart from the first plate, an optical sensor having at least one optical fiber disposed between the first plate and the second plate, and a clamp for moving the first plate and the second plate together to compress the optical fiber, thereby applying a prestressing force to the fiber to reduce eccentricity effects.
