Baro-compensated primary measuring transformer with solid sensitive element (variants) relates to engineering of measurement of hydro-physical and hydro-chemical parameters of water media in oceanographic, hydrographic and ecological deep-sea investigations. Transformer by first variant has body with tail element. The body is arranged with cavity in cylindrical form filled with liquid that is hermetically separated from pouter medium with sensitive element in cylindrical form. Sensitive element is installed in cavity with liquid through sealing of movable contact with possibility of axial displacement in the cavity. Transformer by another variant has body with tail element. The body is arranged with cavity in cylindrical form filled with liquid and the body is sensitive element. Liquid in the body is hermetically separated from environment. In the cavity through sealing of movable contact cylindrical tail element is installed, with possibility of axial displacement of the body – sensitive element with respect to tail element. By both variants output of sensitive element is made flexible, it goes through cavity with liquid, is electrically insulated and with sealing goes from transformed through tail element. Transformers due to increase of range of working pressure in those provide increase of reliability of operation and accuracy of information obtained from those at simplification of technology of making those. |
