ABSTRACT OF THE DISCLOSURE A mounting structure for resonators used as frequency standards and transducers which maximizes performance and reduces the sensitivity to environmental errors. In one embodiment, force sensitive resonators having inherent unmounted temperature sensitivities are used in conjunction with reactive spring-like mounting arrangements having predetermined temperature stress characteristics such that the thermally induced mechanical stress of the mounting arrangements changes, compensates, and optimizes the overall combined temperature characteristics. In another embodiment resonators are isolated from the external enviroment so that they are capable of sensing forces while operating in a vacuum or inert atmosphere. Enviromental isolation is provided by bellows and/or diaphragm arrangements used along or in conjunc- tion with air-tight enclosures which enable forces to be applied to stress-sensitive resonators while isolating the resonators from the external force producing enviroment.
